PREAMBLE + +The purpose of this License is to make a manual, textbook, or other +functional and useful document "free" in the sense of freedom: to +assure everyone the effective freedom to copy and redistribute it, +with or without modifying it, either commercially or noncommercially. +Secondarily, this License preserves for the author and publisher a way +to get credit for their work, while not being considered responsible +for modifications made by others. + +This License is a kind of "copyleft", which means that derivative +works of the document must themselves be free in the same sense. It +complements the GNU General Public License, which is a copyleft +license designed for free software. + +We have designed this License in order to use it for manuals for free +software, because free software needs free documentation: a free +program should come with manuals providing the same freedoms that the +software does. But this License is not limited to software manuals; +it can be used for any textual work, regardless of subject matter or +whether it is published as a printed book. We recommend this License +principally for works whose purpose is instruction or reference. + + +1. APPLICABILITY AND DEFINITIONS + +This License applies to any manual or other work, in any medium, that +contains a notice placed by the copyright holder saying it can be +distributed under the terms of this License. Such a notice grants a +world-wide, royalty-free license, unlimited in duration, to use that +work under the conditions stated herein. The "Document", below, +refers to any such manual or work. Any member of the public is a +licensee, and is addressed as "you". You accept the license if you +copy, modify or distribute the work in a way requiring permission +under copyright law. + +A "Modified Version" of the Document means any work containing the +Document or a portion of it, either copied verbatim, or with +modifications and/or translated into another language. + +A "Secondary Section" is a named appendix or a front-matter section of +the Document that deals exclusively with the relationship of the +publishers or authors of the Document to the Document's overall subject +(or to related matters) and contains nothing that could fall directly +within that overall subject. (Thus, if the Document is in part a +textbook of mathematics, a Secondary Section may not explain any +mathematics.) The relationship could be a matter of historical +connection with the subject or with related matters, or of legal, +commercial, philosophical, ethical or political position regarding +them. + +The "Invariant Sections" are certain Secondary Sections whose titles +are designated, as being those of Invariant Sections, in the notice +that says that the Document is released under this License. If a +section does not fit the above definition of Secondary then it is not +allowed to be designated as Invariant. The Document may contain zero +Invariant Sections. If the Document does not identify any Invariant +Sections then there are none. + +The "Cover Texts" are certain short passages of text that are listed, +as Front-Cover Texts or Back-Cover Texts, in the notice that says that +the Document is released under this License. A Front-Cover Text may +be at most 5 words, and a Back-Cover Text may be at most 25 words. + +A "Transparent" copy of the Document means a machine-readable copy, +represented in a format whose specification is available to the +general public, that is suitable for revising the document +straightforwardly with generic text editors or (for images composed of +pixels) generic paint programs or (for drawings) some widely available +drawing editor, and that is suitable for input to text formatters or +for automatic translation to a variety of formats suitable for input +to text formatters. A copy made in an otherwise Transparent file +format whose markup, or absence of markup, has been arranged to thwart +or discourage subsequent modification by readers is not Transparent. +An image format is not Transparent if used for any substantial amount +of text. A copy that is not "Transparent" is called "Opaque". + +Examples of suitable formats for Transparent copies include plain +ASCII without markup, Texinfo input format, LaTeX input format, SGML +or XML using a publicly available DTD, and standard-conforming simple +HTML, PostScript or PDF designed for human modification. Examples of +transparent image formats include PNG, XCF and JPG. Opaque formats +include proprietary formats that can be read and edited only by +proprietary word processors, SGML or XML for which the DTD and/or +processing tools are not generally available, and the +machine-generated HTML, PostScript or PDF produced by some word +processors for output purposes only. + +The "Title Page" means, for a printed book, the title page itself, +plus such following pages as are needed to hold, legibly, the material +this License requires to appear in the title page. For works in +formats which do not have any title page as such, "Title Page" means +the text near the most prominent appearance of the work's title, +preceding the beginning of the body of the text. + +A section "Entitled XYZ" means a named subunit of the Document whose +title either is precisely XYZ or contains XYZ in parentheses following +text that translates XYZ in another language. (Here XYZ stands for a +specific section name mentioned below, such as "Acknowledgements", +"Dedications", "Endorsements", or "History".) To "Preserve the Title" +of such a section when you modify the Document means that it remains a +section "Entitled XYZ" according to this definition. + +The Document may include Warranty Disclaimers next to the notice which +states that this License applies to the Document. These Warranty +Disclaimers are considered to be included by reference in this +License, but only as regards disclaiming warranties: any other +implication that these Warranty Disclaimers may have is void and has +no effect on the meaning of this License. + + +2. VERBATIM COPYING + +You may copy and distribute the Document in any medium, either +commercially or noncommercially, provided that this License, the +copyright notices, and the license notice saying this License applies +to the Document are reproduced in all copies, and that you add no other +conditions whatsoever to those of this License. You may not use +technical measures to obstruct or control the reading or further +copying of the copies you make or distribute. However, you may accept +compensation in exchange for copies. If you distribute a large enough +number of copies you must also follow the conditions in section 3. + +You may also lend copies, under the same conditions stated above, and +you may publicly display copies. + + +3. COPYING IN QUANTITY + +If you publish printed copies (or copies in media that commonly have +printed covers) of the Document, numbering more than 100, and the +Document's license notice requires Cover Texts, you must enclose the +copies in covers that carry, clearly and legibly, all these Cover +Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on +the back cover. Both covers must also clearly and legibly identify +you as the publisher of these copies. The front cover must present +the full title with all words of the title equally prominent and +visible. You may add other material on the covers in addition. +Copying with changes limited to the covers, as long as they preserve +the title of the Document and satisfy these conditions, can be treated +as verbatim copying in other respects. + +If the required texts for either cover are too voluminous to fit +legibly, you should put the first ones listed (as many as fit +reasonably) on the actual cover, and continue the rest onto adjacent +pages. + +If you publish or distribute Opaque copies of the Document numbering +more than 100, you must either include a machine-readable Transparent +copy along with each Opaque copy, or state in or with each Opaque copy +a computer-network location from which the general network-using +public has access to download using public-standard network protocols +a complete Transparent copy of the Document, free of added material. +If you use the latter option, you must take reasonably prudent steps, +when you begin distribution of Opaque copies in quantity, to ensure +that this Transparent copy will remain thus accessible at the stated +location until at least one year after the last time you distribute an +Opaque copy (directly or through your agents or retailers) of that +edition to the public. + +It is requested, but not required, that you contact the authors of the +Document well before redistributing any large number of copies, to give +them a chance to provide you with an updated version of the Document. + + +4. MODIFICATIONS + +You may copy and distribute a Modified Version of the Document under +the conditions of sections 2 and 3 above, provided that you release +the Modified Version under precisely this License, with the Modified +Version filling the role of the Document, thus licensing distribution +and modification of the Modified Version to whoever possesses a copy +of it. In addition, you must do these things in the Modified Version: + +A. Use in the Title Page (and on the covers, if any) a title distinct + from that of the Document, and from those of previous versions + (which should, if there were any, be listed in the History section + of the Document). You may use the same title as a previous version + if the original publisher of that version gives permission. +B. List on the Title Page, as authors, one or more persons or entities + responsible for authorship of the modifications in the Modified + Version, together with at least five of the principal authors of the + Document (all of its principal authors, if it has fewer than five), + unless they release you from this requirement. +C. State on the Title page the name of the publisher of the + Modified Version, as the publisher. +D. Preserve all the copyright notices of the Document. +E. Add an appropriate copyright notice for your modifications + adjacent to the other copyright notices. +F. Include, immediately after the copyright notices, a license notice + giving the public permission to use the Modified Version under the + terms of this License, in the form shown in the Addendum below. +G. Preserve in that license notice the full lists of Invariant Sections + and required Cover Texts given in the Document's license notice. +H. Include an unaltered copy of this License. +I. Preserve the section Entitled "History", Preserve its Title, and add + to it an item stating at least the title, year, new authors, and + publisher of the Modified Version as given on the Title Page. If + there is no section Entitled "History" in the Document, create one + stating the title, year, authors, and publisher of the Document as + given on its Title Page, then add an item describing the Modified + Version as stated in the previous sentence. +J. Preserve the network location, if any, given in the Document for + public access to a Transparent copy of the Document, and likewise + the network locations given in the Document for previous versions + it was based on. These may be placed in the "History" section. + You may omit a network location for a work that was published at + least four years before the Document itself, or if the original + publisher of the version it refers to gives permission. +K. For any section Entitled "Acknowledgements" or "Dedications", + Preserve the Title of the section, and preserve in the section all + the substance and tone of each of the contributor acknowledgements + and/or dedications given therein. +L. Preserve all the Invariant Sections of the Document, + unaltered in their text and in their titles. Section numbers + or the equivalent are not considered part of the section titles. +M. Delete any section Entitled "Endorsements". Such a section + may not be included in the Modified Version. +N. Do not retitle any existing section to be Entitled "Endorsements" + or to conflict in title with any Invariant Section. +O. Preserve any Warranty Disclaimers. + +If the Modified Version includes new front-matter sections or +appendices that qualify as Secondary Sections and contain no material +copied from the Document, you may at your option designate some or all +of these sections as invariant. To do this, add their titles to the +list of Invariant Sections in the Modified Version's license notice. +These titles must be distinct from any other section titles. + +You may add a section Entitled "Endorsements", provided it contains +nothing but endorsements of your Modified Version by various +parties--for example, statements of peer review or that the text has +been approved by an organization as the authoritative definition of a +standard. + +You may add a passage of up to five words as a Front-Cover Text, and a +passage of up to 25 words as a Back-Cover Text, to the end of the list +of Cover Texts in the Modified Version. Only one passage of +Front-Cover Text and one of Back-Cover Text may be added by (or +through arrangements made by) any one entity. If the Document already +includes a cover text for the same cover, previously added by you or +by arrangement made by the same entity you are acting on behalf of, +you may not add another; but you may replace the old one, on explicit +permission from the previous publisher that added the old one. + +The author(s) and publisher(s) of the Document do not by this License +give permission to use their names for publicity for or to assert or +imply endorsement of any Modified Version. + + +5. COMBINING DOCUMENTS + +You may combine the Document with other documents released under this +License, under the terms defined in section 4 above for modified +versions, provided that you include in the combination all of the +Invariant Sections of all of the original documents, unmodified, and +list them all as Invariant Sections of your combined work in its +license notice, and that you preserve all their Warranty Disclaimers. + +The combined work need only contain one copy of this License, and +multiple identical Invariant Sections may be replaced with a single +copy. If there are multiple Invariant Sections with the same name but +different contents, make the title of each such section unique by +adding at the end of it, in parentheses, the name of the original +author or publisher of that section if known, or else a unique number. +Make the same adjustment to the section titles in the list of +Invariant Sections in the license notice of the combined work. + +In the combination, you must combine any sections Entitled "History" +in the various original documents, forming one section Entitled +"History"; likewise combine any sections Entitled "Acknowledgements", +and any sections Entitled "Dedications". You must delete all sections +Entitled "Endorsements". + + +6. COLLECTIONS OF DOCUMENTS + +You may make a collection consisting of the Document and other documents +released under this License, and replace the individual copies of this +License in the various documents with a single copy that is included in +the collection, provided that you follow the rules of this License for +verbatim copying of each of the documents in all other respects. + +You may extract a single document from such a collection, and distribute +it individually under this License, provided you insert a copy of this +License into the extracted document, and follow this License in all +other respects regarding verbatim copying of that document. + + +7. AGGREGATION WITH INDEPENDENT WORKS + +A compilation of the Document or its derivatives with other separate +and independent documents or works, in or on a volume of a storage or +distribution medium, is called an "aggregate" if the copyright +resulting from the compilation is not used to limit the legal rights +of the compilation's users beyond what the individual works permit. +When the Document is included in an aggregate, this License does not +apply to the other works in the aggregate which are not themselves +derivative works of the Document. + +If the Cover Text requirement of section 3 is applicable to these +copies of the Document, then if the Document is less than one half of +the entire aggregate, the Document's Cover Texts may be placed on +covers that bracket the Document within the aggregate, or the +electronic equivalent of covers if the Document is in electronic form. +Otherwise they must appear on printed covers that bracket the whole +aggregate. + + +8. TRANSLATION + +Translation is considered a kind of modification, so you may +distribute translations of the Document under the terms of section 4. +Replacing Invariant Sections with translations requires special +permission from their copyright holders, but you may include +translations of some or all Invariant Sections in addition to the +original versions of these Invariant Sections. You may include a +translation of this License, and all the license notices in the +Document, and any Warranty Disclaimers, provided that you also include +the original English version of this License and the original versions +of those notices and disclaimers. In case of a disagreement between +the translation and the original version of this License or a notice +or disclaimer, the original version will prevail. + +If a section in the Document is Entitled "Acknowledgements", +"Dedications", or "History", the requirement (section 4) to Preserve +its Title (section 1) will typically require changing the actual +title. + + +9. TERMINATION + +You may not copy, modify, sublicense, or distribute the Document except +as expressly provided for under this License. Any other attempt to +copy, modify, sublicense or distribute the Document is void, and will +automatically terminate your rights under this License. However, +parties who have received copies, or rights, from you under this +License will not have their licenses terminated so long as such +parties remain in full compliance. + + +10. FUTURE REVISIONS OF THIS LICENSE + +The Free Software Foundation may publish new, revised versions +of the GNU Free Documentation License from time to time. Such new +versions will be similar in spirit to the present version, but may +differ in detail to address new problems or concerns. See +http://www.gnu.org/copyleft/. + +Each version of the License is given a distinguishing version number. +If the Document specifies that a particular numbered version of this +License "or any later version" applies to it, you have the option of +following the terms and conditions either of that specified version or +of any later version that has been published (not as a draft) by the +Free Software Foundation. If the Document does not specify a version +number of this License, you may choose any version ever published (not +as a draft) by the Free Software Foundation. + + +ADDENDUM: How to use this License for your documents + +To use this License in a document you have written, include a copy of +the License in the document and put the following copyright and +license notices just after the title page: + + Copyright (c) YEAR YOUR NAME. + Permission is granted to copy, distribute and/or modify this document + under the terms of the GNU Free Documentation License, Version 1.2 + or any later version published by the Free Software Foundation; + with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. + A copy of the license is included in the section entitled "GNU + Free Documentation License". + +If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts, +replace the "with...Texts." line with this: + + with the Invariant Sections being LIST THEIR TITLES, with the + Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST. + +If you have Invariant Sections without Cover Texts, or some other +combination of the three, merge those two alternatives to suit the +situation. + +If your document contains nontrivial examples of program code, we +recommend releasing these examples in parallel under your choice of +free software license, such as the GNU General Public License, +to permit their use in free software. diff --git a/vendor/flac/COPYING.GPL b/vendor/flac/COPYING.GPL new file mode 100644 index 0000000..d159169 --- /dev/null +++ b/vendor/flac/COPYING.GPL @@ -0,0 +1,339 @@ + GNU GENERAL PUBLIC LICENSE + Version 2, June 1991 + + Copyright (C) 1989, 1991 Free Software Foundation, Inc., + 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA + Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed. + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Lesser General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License along + with this program; if not, write to the Free Software Foundation, Inc., + 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) year name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary. Here is a sample; alter the names: + + Yoyodyne, Inc., hereby disclaims all copyright interest in the program + `Gnomovision' (which makes passes at compilers) written by James Hacker. + + , 1 April 1989 + Ty Coon, President of Vice + +This General Public License does not permit incorporating your program into +proprietary programs.

By contrast, the GNU General Public +Licenses are intended to guarantee your freedom to share and change +free software--to make sure the software is free for all its users. + + This license, the Lesser General Public License, applies to some +specially designated software packages--typically libraries--of the +Free Software Foundation and other authors who decide to use it. You +can use it too, but we suggest you first think carefully about whether +this license or the ordinary General Public License is the better +strategy to use in any particular case, based on the explanations below. + + When we speak of free software, we are referring to freedom of use, +not price. Our General Public Licenses are designed to make sure that +you have the freedom to distribute copies of free software (and charge +for this service if you wish); that you receive source code or can get +it if you want it; that you can change the software and use pieces of +it in new free programs; and that you are informed that you can do +these things. + + To protect your rights, we need to make restrictions that forbid +distributors to deny you these rights or to ask you to surrender these +rights. These restrictions translate to certain responsibilities for +you if you distribute copies of the library or if you modify it. + + For example, if you distribute copies of the library, whether gratis +or for a fee, you must give the recipients all the rights that we gave +you. You must make sure that they, too, receive or can get the source +code. If you link other code with the library, you must provide +complete object files to the recipients, so that they can relink them +with the library after making changes to the library and recompiling +it. And you must show them these terms so they know their rights. + + We protect your rights with a two-step method: (1) we copyright the +library, and (2) we offer you this license, which gives you legal +permission to copy, distribute and/or modify the library. + + To protect each distributor, we want to make it very clear that +there is no warranty for the free library. Also, if the library is +modified by someone else and passed on, the recipients should know +that what they have is not the original version, so that the original +author's reputation will not be affected by problems that might be +introduced by others. + + Finally, software patents pose a constant threat to the existence of +any free program. We wish to make sure that a company cannot +effectively restrict the users of a free program by obtaining a +restrictive license from a patent holder. Therefore, we insist that +any patent license obtained for a version of the library must be +consistent with the full freedom of use specified in this license. + + Most GNU software, including some libraries, is covered by the +ordinary GNU General Public License. This license, the GNU Lesser +General Public License, applies to certain designated libraries, and +is quite different from the ordinary General Public License. We use +this license for certain libraries in order to permit linking those +libraries into non-free programs. + + When a program is linked with a library, whether statically or using +a shared library, the combination of the two is legally speaking a +combined work, a derivative of the original library. The ordinary +General Public License therefore permits such linking only if the +entire combination fits its criteria of freedom. The Lesser General +Public License permits more lax criteria for linking other code with +the library. + + We call this license the "Lesser" General Public License because it +does Less to protect the user's freedom than the ordinary General +Public License. It also provides other free software developers Less +of an advantage over competing non-free programs. These disadvantages +are the reason we use the ordinary General Public License for many +libraries. However, the Lesser license provides advantages in certain +special circumstances. + + For example, on rare occasions, there may be a special need to +encourage the widest possible use of a certain library, so that it becomes +a de-facto standard. To achieve this, non-free programs must be +allowed to use the library. A more frequent case is that a free +library does the same job as widely used non-free libraries. In this +case, there is little to gain by limiting the free library to free +software only, so we use the Lesser General Public License. + + In other cases, permission to use a particular library in non-free +programs enables a greater number of people to use a large body of +free software. For example, permission to use the GNU C Library in +non-free programs enables many more people to use the whole GNU +operating system, as well as its variant, the GNU/Linux operating +system. + + Although the Lesser General Public License is Less protective of the +users' freedom, it does ensure that the user of a program that is +linked with the Library has the freedom and the wherewithal to run +that program using a modified version of the Library. + + The precise terms and conditions for copying, distribution and +modification follow. Pay close attention to the difference between a +"work based on the library" and a "work that uses the library". The +former contains code derived from the library, whereas the latter must +be combined with the library in order to run. + + GNU LESSER GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library or other +program which contains a notice placed by the copyright holder or +other authorized party saying it may be distributed under the terms of +this Lesser General Public License (also called "this License"). +Each licensee is addressed as "you". + + A "library" means a collection of software functions and/or data +prepared so as to be conveniently linked with application programs +(which use some of those functions and data) to form executables. + + The "Library", below, refers to any such software library or work +which has been distributed under these terms. A "work based on the +Library" means either the Library or any derivative work under +copyright law: that is to say, a work containing the Library or a +portion of it, either verbatim or with modifications and/or translated +straightforwardly into another language. (Hereinafter, translation is +included without limitation in the term "modification".) + + "Source code" for a work means the preferred form of the work for +making modifications to it. For a library, complete source code means +all the source code for all modules it contains, plus any associated +interface definition files, plus the scripts used to control compilation +and installation of the library. + + Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running a program using the Library is not restricted, and output from +such a program is covered only if its contents constitute a work based +on the Library (independent of the use of the Library in a tool for +writing it). Whether that is true depends on what the Library does +and what the program that uses the Library does. + + 1. You may copy and distribute verbatim copies of the Library's +complete source code as you receive it, in any medium, provided that +you conspicuously and appropriately publish on each copy an +appropriate copyright notice and disclaimer of warranty; keep intact +all the notices that refer to this License and to the absence of any +warranty; and distribute a copy of this License along with the +Library. + + You may charge a fee for the physical act of transferring a copy, +and you may at your option offer warranty protection in exchange for a +fee. + + 2. You may modify your copy or copies of the Library or any portion +of it, thus forming a work based on the Library, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) The modified work must itself be a software library. + + b) You must cause the files modified to carry prominent notices + stating that you changed the files and the date of any change. + + c) You must cause the whole of the work to be licensed at no + charge to all third parties under the terms of this License. + + d) If a facility in the modified Library refers to a function or a + table of data to be supplied by an application program that uses + the facility, other than as an argument passed when the facility + is invoked, then you must make a good faith effort to ensure that, + in the event an application does not supply such function or + table, the facility still operates, and performs whatever part of + its purpose remains meaningful. + + (For example, a function in a library to compute square roots has + a purpose that is entirely well-defined independent of the + application. Therefore, Subsection 2d requires that any + application-supplied function or table used by this function must + be optional: if the application does not supply it, the square + root function must still compute square roots.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Library, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Library, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote +it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Library. + +In addition, mere aggregation of another work not based on the Library +with the Library (or with a work based on the Library) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may opt to apply the terms of the ordinary GNU General Public +License instead of this License to a given copy of the Library. To do +this, you must alter all the notices that refer to this License, so +that they refer to the ordinary GNU General Public License, version 2, +instead of to this License. (If a newer version than version 2 of the +ordinary GNU General Public License has appeared, then you can specify +that version instead if you wish.) Do not make any other change in +these notices. + + Once this change is made in a given copy, it is irreversible for +that copy, so the ordinary GNU General Public License applies to all +subsequent copies and derivative works made from that copy. + + This option is useful when you wish to copy part of the code of +the Library into a program that is not a library. + + 4. You may copy and distribute the Library (or a portion or +derivative of it, under Section 2) in object code or executable form +under the terms of Sections 1 and 2 above provided that you accompany +it with the complete corresponding machine-readable source code, which +must be distributed under the terms of Sections 1 and 2 above on a +medium customarily used for software interchange. + + If distribution of object code is made by offering access to copy +from a designated place, then offering equivalent access to copy the +source code from the same place satisfies the requirement to +distribute the source code, even though third parties are not +compelled to copy the source along with the object code. + + 5. A program that contains no derivative of any portion of the +Library, but is designed to work with the Library by being compiled or +linked with it, is called a "work that uses the Library". Such a +work, in isolation, is not a derivative work of the Library, and +therefore falls outside the scope of this License. + + However, linking a "work that uses the Library" with the Library +creates an executable that is a derivative of the Library (because it +contains portions of the Library), rather than a "work that uses the +library". The executable is therefore covered by this License. +Section 6 states terms for distribution of such executables. + + When a "work that uses the Library" uses material from a header file +that is part of the Library, the object code for the work may be a +derivative work of the Library even though the source code is not. +Whether this is true is especially significant if the work can be +linked without the Library, or if the work is itself a library. The +threshold for this to be true is not precisely defined by law. + + If such an object file uses only numerical parameters, data +structure layouts and accessors, and small macros and small inline +functions (ten lines or less in length), then the use of the object +file is unrestricted, regardless of whether it is legally a derivative +work. (Executables containing this object code plus portions of the +Library will still fall under Section 6.) + + Otherwise, if the work is a derivative of the Library, you may +distribute the object code for the work under the terms of Section 6. +Any executables containing that work also fall under Section 6, +whether or not they are linked directly with the Library itself. + + 6. As an exception to the Sections above, you may also combine or +link a "work that uses the Library" with the Library to produce a +work containing portions of the Library, and distribute that work +under terms of your choice, provided that the terms permit +modification of the work for the customer's own use and reverse +engineering for debugging such modifications. + + You must give prominent notice with each copy of the work that the +Library is used in it and that the Library and its use are covered by +this License. You must supply a copy of this License. If the work +during execution displays copyright notices, you must include the +copyright notice for the Library among them, as well as a reference +directing the user to the copy of this License. Also, you must do one +of these things: + + a) Accompany the work with the complete corresponding + machine-readable source code for the Library including whatever + changes were used in the work (which must be distributed under + Sections 1 and 2 above); and, if the work is an executable linked + with the Library, with the complete machine-readable "work that + uses the Library", as object code and/or source code, so that the + user can modify the Library and then relink to produce a modified + executable containing the modified Library. (It is understood + that the user who changes the contents of definitions files in the + Library will not necessarily be able to recompile the application + to use the modified definitions.) + + b) Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (1) uses at run time a + copy of the library already present on the user's computer system, + rather than copying library functions into the executable, and (2) + will operate properly with a modified version of the library, if + the user installs one, as long as the modified version is + interface-compatible with the version that the work was made with. + + c) Accompany the work with a written offer, valid for at + least three years, to give the same user the materials + specified in Subsection 6a, above, for a charge no more + than the cost of performing this distribution. + + d) If distribution of the work is made by offering access to copy + from a designated place, offer equivalent access to copy the above + specified materials from the same place. + + e) Verify that the user has already received a copy of these + materials or that you have already sent this user a copy. + + For an executable, the required form of the "work that uses the +Library" must include any data and utility programs needed for +reproducing the executable from it. However, as a special exception, +the materials to be distributed need not include anything that is +normally distributed (in either source or binary form) with the major +components (compiler, kernel, and so on) of the operating system on +which the executable runs, unless that component itself accompanies +the executable. + + It may happen that this requirement contradicts the license +restrictions of other proprietary libraries that do not normally +accompany the operating system. Such a contradiction means you cannot +use both them and the Library together in an executable that you +distribute. + + 7. You may place library facilities that are a work based on the +Library side-by-side in a single library together with other library +facilities not covered by this License, and distribute such a combined +library, provided that the separate distribution of the work based on +the Library and of the other library facilities is otherwise +permitted, and provided that you do these two things: + + a) Accompany the combined library with a copy of the same work + based on the Library, uncombined with any other library + facilities. This must be distributed under the terms of the + Sections above. + + b) Give prominent notice with the combined library of the fact + that part of it is a work based on the Library, and explaining + where to find the accompanying uncombined form of the same work. + + 8. You may not copy, modify, sublicense, link with, or distribute +the Library except as expressly provided under this License. Any +attempt otherwise to copy, modify, sublicense, link with, or +distribute the Library is void, and will automatically terminate your +rights under this License. However, parties who have received copies, +or rights, from you under this License will not have their licenses +terminated so long as such parties remain in full compliance. + + 9. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Library or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Library (or any work based on the +Library), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Library or works based on it. + + 10. Each time you redistribute the Library (or any work based on the +Library), the recipient automatically receives a license from the +original licensor to copy, distribute, link with or modify the Library +subject to these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties with +this License. + + 11. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Library at all. For example, if a patent +license would not permit royalty-free redistribution of the Library by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Library. + +If any portion of this section is held invalid or unenforceable under any +particular circumstance, the balance of the section is intended to apply, +and the section as a whole is intended to apply in other circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 12. If the distribution and/or use of the Library is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Library under this License may add +an explicit geographical distribution limitation excluding those countries, +so that distribution is permitted only in or among countries not thus +excluded. In such case, this License incorporates the limitation as if +written in the body of this License. + + 13. The Free Software Foundation may publish revised and/or new +versions of the Lesser General Public License from time to time. +Such new versions will be similar in spirit to the present version, +but may differ in detail to address new problems or concerns. + +Each version is given a distinguishing version number. If the Library +specifies a version number of this License which applies to it and +"any later version", you have the option of following the terms and +conditions either of that version or of any later version published by +the Free Software Foundation. If the Library does not specify a +license version number, you may choose any version ever published by +the Free Software Foundation. + + 14. If you wish to incorporate parts of the Library into other free +programs whose distribution conditions are incompatible with these, +write to the author to ask for permission. For software which is +copyrighted by the Free Software Foundation, write to the Free +Software Foundation; we sometimes make exceptions for this. Our +decision will be guided by the two goals of preserving the free status +of all derivatives of our free software and of promoting the sharing +and reuse of software generally. + + NO WARRANTY + + 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO +WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. +EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR +OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY +KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE +IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE +LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME +THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN +WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY +AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU +FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR +CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE +LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING +RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A +FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF +SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH +DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Libraries + + If you develop a new library, and you want it to be of the greatest +possible use to the public, we recommend making it free software that +everyone can redistribute and change. You can do so by permitting +redistribution under these terms (or, alternatively, under the terms of the +ordinary General Public License). + + To apply these terms, attach the following notices to the library. It is +safest to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least the +"copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + This library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Both differ slighly in configuration options, but +should be considered equivalent for most use cases. + +FLAC used to provide files specifically for building with Visual Studio, +but these have been removed in favor of using CMake. + +## Building with CMake + +CMake is a cross-platform build system. FLAC can be built on Windows, +Linux, Mac OS X using CMake. + +You can use either CMake's CLI or GUI. We recommend you to have a +separate build folder outside the repository in order to not spoil it +with generated files. It is possible however to do a so-called in-tree +build, in that case /path/to/flac-build in the following examples is +equal to /path/to/flac-source. + +### CMake CLI + +Go to your build folder and run something like this: + +``` +/path/to/flac-build$ cmake /path/to/flac-source +``` + +or e.g. in Windows shell + +``` +C:\path\to\flac-build> cmake \path\to\flac-source +``` + +(provided that cmake is in your %PATH% variable) + +That will generate build scripts for the default build system (e.g. +Makefiles for UNIX). After that you start build with a command like +this: + +``` +/path/to/flac-build$ make +``` + +And afterwards you can run tests or install the built libraries and +headers + +``` +/path/to/flac-build$ make test +/path/to/flac-build$ make install +``` + +If you want use a build system other than default add -G flag to cmake, +e.g.: + +``` +/path/to/flac-build$ cmake /path/to/flac-source -GNinja +/path/to/flac-build$ ninja +``` + +or: + +``` +/path/to/flac-build$ cmake /path/to/flac-source -GXcode +``` + +Use cmake --help to see the list of available generators. + +By default CMake will search for OGG. If CMake fails to find it you can +help CMake by specifying the exact path: + +``` +/path/to/flac-build$ cmake /path/to/flac-source -DOGG_ROOT=/path/to/ogg +``` + +If you would like CMake to build OGG alongside FLAC, you can place the +ogg sources directly in the flac source directory as a subdirectory with +the name ogg, for example: + +``` +/path/to/flac-source/ogg +``` + +If you don't want to build flac with OGG support you can tell CMake not +to look for OGG: + +``` +/path/to/flac-build$ cmake /path/to/flac-source -DWITH_OGG=OFF +``` + +Other FLAC's options (e.g. building C++ lib or docs) can also be put to +cmake through -D flag. If you want to know what options are available, +use -LH: + +``` +/path/to/flac-build$ cmake /path/to/flac-source -LH +``` + +### CMake GUI (for Visual Studio) +It is likely that you would prefer to use the CMake GUI if you use +Visual Studio to build FLAC. It's in essence the same process as +building using CLI. + +Open cmake-gui. In the window select a source directory (the +repository's root), a build directory (some other directory outside the +repository). Then press button "Configure". CMake will ask you which +build system you prefer. Choose that version of Visual Studio which you +have on your system, choose whether you want to build for Win32 or x64. +Press OK. + +After CMake finishes you can change the configuration to your liking and +if you change anything, run Configure again. With the "Generate" button, +CMake creates Visual Studio files, which can be opened from Visual +Studio. With the button "Open Project" CMake will launch Visual Studio +and open the generated solution. You can use the project files as usual +but remember that they were generated by CMake. That means that your +changes (e.g. some additional compile flags) will be lost when you run +CMake next time. + +CMake searches by default for OGG on your system and returns an error +if it cannot find it. If you want to build OGG alongside FLAC, you can +download the OGG sources and extract them in a subdirectory of the FLAC +source directory with the name ogg (i.e. /path/to/flac-source/ogg) +before running CMake. If you don't want to build FLAC with OGG support, +untick the box following WITH_OGG flag in the list of variables in +cmake-gui window and run "Configure" again. + +If CMake fails to find MSVC compiler then running cmake-gui from MS +Developer comand prompt should help. + +## Building with GNU autotools + +FLAC uses autoconf and libtool for configuring and building. To +configure a build, open a commmand line/terminal and run `./configure` +You can provide options to this command, which are listed by running +`./configure --help`. + +In case the configure script is not present (for example when building +from git and not from a release tarball), it can be generated by running +`./autogen.sh`. This may require a libtool development package though. + +After configuration, build with `make`, verify the build with +`make check` and install with `make install`. Installation might require +administrator priviledged, i.e. `sudo make install`. + +The 'make check' step is optional; omit it to skip all the tests, which +can take about an hour to complete. Even though it will stop with an +explicit message on any failure, it does print out a lot of stuff so you +might want to capture the output to a file if you're having a problem. +Also, don't run 'make check' as root because it confuses some of the +tests. + +Summarizing: + +``` +./configure +make && make check +sudo make install +``` + +## Note to embedded developers + +libFLAC has grown larger over time as more functionality has been +included, but much of it may be unnecessary for a particular embedded +implementation. Unused parts may be pruned by some simple editing of +configure.ac and src/libFLAC/Makefile.am; the following dependency +graph shows which modules may be pruned without breaking things +further down: + +``` +metadata.h + stream_decoder.h + format.h + +stream_encoder.h + stream_decoder.h + format.h + +stream_decoder.h + format.h +``` + +In other words, for pure decoding applications, both the stream encoder +and metadata editing interfaces can be safely removed. Note that this +is specific to building the libraries for embedded use. The command line +tools do not provide such compartmentalization, and require a complete +libFLAC build to function. + +There is a section dedicated to embedded use in the libFLAC API +HTML documentation (see doc/html/api/index.html). + +Also, there are several places in the libFLAC code with comments marked +with "OPT:" where a #define can be changed to enable code that might be +faster on a specific platform.

It is + * highly interconnected; this introduction should give you a top + * level idea of the structure and how to find the information you + * need. As a prerequisite you should have at least a basic + * knowledge of the FLAC format, documented + * here. + * + * \section c_api FLAC C API + * + * The FLAC C API is the interface to libFLAC, a set of structures + * describing the components of FLAC streams, and functions for + * encoding and decoding streams, as well as manipulating FLAC + * metadata in files. The public include files will be installed + * in your include area (for example /usr/include/FLAC/...). + * + * By writing a little code and linking against libFLAC, it is + * relatively easy to add FLAC support to another program. The + * library is licensed under Xiph's BSD license. + * Complete source code of libFLAC as well as the command-line + * encoder and plugins is available and is a useful source of + * examples. + * + * Aside from encoders and decoders, libFLAC provides a powerful + * metadata interface for manipulating metadata in FLAC files. It + * allows the user to add, delete, and modify FLAC metadata blocks + * and it can automatically take advantage of PADDING blocks to avoid + * rewriting the entire FLAC file when changing the size of the + * metadata. + * + * libFLAC usually only requires the standard C library and C math + * library. In particular, threading is not used so there is no + * dependency on a thread library. However, libFLAC does not use + * global variables and should be thread-safe. + * + * libFLAC also supports encoding to and decoding from Ogg FLAC. + * However the metadata editing interfaces currently have limited + * read-only support for Ogg FLAC files. + * + * \section cpp_api FLAC C++ API + * + * The FLAC C++ API is a set of classes that encapsulate the + * structures and functions in libFLAC. They provide slightly more + * functionality with respect to metadata but are otherwise + * equivalent. For the most part, they share the same usage as + * their counterparts in libFLAC, and the FLAC C API documentation + * can be used as a supplement. The public include files + * for the C++ API will be installed in your include area (for + * example /usr/include/FLAC++/...). + * + * libFLAC++ is also licensed under + * Xiph's BSD license. + * + * \section getting_started Getting Started + * + * A good starting point for learning the API is to browse through + * the modules. Modules are logical + * groupings of related functions or classes, which correspond roughly + * to header files or sections of header files. Each module includes a + * detailed description of the general usage of its functions or + * classes. + * + * From there you can go on to look at the documentation of + * individual functions. You can see different views of the individual + * functions through the links in top bar across this page. + * + * If you prefer a more hands-on approach, you can jump right to some + * example code. + * + * \section porting_guide Porting Guide + * + * Starting with FLAC 1.1.3 a \link porting Porting Guide \endlink + * has been introduced which gives detailed instructions on how to + * port your code to newer versions of FLAC. + * + * \section embedded_developers Embedded Developers + * + * libFLAC has grown larger over time as more functionality has been + * included, but much of it may be unnecessary for a particular embedded + * implementation. Unused parts may be pruned by some simple editing of + * src/libFLAC/Makefile.am. In general, the decoders, encoders, and + * metadata interface are all independent from each other. + * + * It is easiest to just describe the dependencies: + * + * - All modules depend on the \link flac_format Format \endlink module. + * - The decoders and encoders depend on the bitbuffer. + * - The decoder is independent of the encoder. The encoder uses the + * decoder because of the verify feature, but this can be removed if + * not needed. + * - Parts of the metadata interface require the stream decoder (but not + * the encoder). + * - Ogg support is selectable through the compile time macro + * \c FLAC__HAS_OGG. + * + * For example, if your application only requires the stream decoder, no + * encoder, and no metadata interface, you can remove the stream encoder + * and the metadata interface, which will greatly reduce the size of the + * library. + * + * Also, there are several places in the libFLAC code with comments marked + * with "OPT:" where a \#define can be changed to enable code that might be + * faster on a specific platform. Experimenting with these can yield faster + * binaries. + */ + +/** \defgroup porting Porting Guide for New Versions + * + * This module describes differences in the library interfaces from + * version to version. It assists in the porting of code that uses + * the libraries to newer versions of FLAC. + * + * One simple facility for making porting easier that has been added + * in FLAC 1.1.3 is a set of \#defines in \c export.h of each + * library's includes (e.g. \c include/FLAC/export.h). The + * \#defines mirror the libraries' + * libtool version numbers, + * e.g. in libFLAC there are \c FLAC_API_VERSION_CURRENT, + * \c FLAC_API_VERSION_REVISION, and \c FLAC_API_VERSION_AGE. + * These can be used to support multiple versions of an API during the + * transition phase, e.g. + * + * \code + * #if !defined(FLAC_API_VERSION_CURRENT) || FLAC_API_VERSION_CURRENT <= 7 + * legacy code + * #else + * new code + * #endif + * \endcode + * + * The source will work for multiple versions and the legacy code can + * easily be removed when the transition is complete. + * + * Another available symbol is FLAC_API_SUPPORTS_OGG_FLAC (defined in + * include/FLAC/export.h), which can be used to determine whether or not + * the library has been compiled with support for Ogg FLAC. This is + * simpler than trying to call an Ogg init function and catching the + * error. + */ + +/** \defgroup porting_1_1_2_to_1_1_3 Porting from FLAC 1.1.2 to 1.1.3 + * \ingroup porting + * + * \brief + * This module describes porting from FLAC 1.1.2 to FLAC 1.1.3. + * + * The main change between the APIs in 1.1.2 and 1.1.3 is that they have + * been simplified. First, libOggFLAC has been merged into libFLAC and + * libOggFLAC++ has been merged into libFLAC++. Second, both the three + * decoding layers and three encoding layers have been merged into a + * single stream decoder and stream encoder. That is, the functionality + * of FLAC__SeekableStreamDecoder and FLAC__FileDecoder has been merged + * into FLAC__StreamDecoder, and FLAC__SeekableStreamEncoder and + * FLAC__FileEncoder into FLAC__StreamEncoder. Only the + * FLAC__StreamDecoder and FLAC__StreamEncoder remain. What this means + * is there is now a single API that can be used to encode or decode + * streams to/from native FLAC or Ogg FLAC and the single API can work + * on both seekable and non-seekable streams. + * + * Instead of creating an encoder or decoder of a certain layer, now the + * client will always create a FLAC__StreamEncoder or + * FLAC__StreamDecoder. The old layers are now differentiated by the + * initialization function. For example, for the decoder, + * FLAC__stream_decoder_init() has been replaced by + * FLAC__stream_decoder_init_stream(). This init function takes + * callbacks for the I/O, and the seeking callbacks are optional. This + * allows the client to use the same object for seekable and + * non-seekable streams. For decoding a FLAC file directly, the client + * can use FLAC__stream_decoder_init_file() and pass just a filename + * and fewer callbacks; most of the other callbacks are supplied + * internally. For situations where fopen()ing by filename is not + * possible (e.g. Unicode filenames on Windows) the client can instead + * open the file itself and supply the FILE* to + * FLAC__stream_decoder_init_FILE(). The init functions now returns a + * FLAC__StreamDecoderInitStatus instead of FLAC__StreamDecoderState. + * Since the callbacks and client data are now passed to the init + * function, the FLAC__stream_decoder_set_*_callback() functions and + * FLAC__stream_decoder_set_client_data() are no longer needed. The + * rest of the calls to the decoder are the same as before. + * + * There are counterpart init functions for Ogg FLAC, e.g. + * FLAC__stream_decoder_init_ogg_stream(). All the rest of the calls + * and callbacks are the same as for native FLAC. + * + * As an example, in FLAC 1.1.2 a seekable stream decoder would have + * been set up like so: + * + * \code + * FLAC__SeekableStreamDecoder *decoder = FLAC__seekable_stream_decoder_new(); + * if(decoder == NULL) do_something; + * FLAC__seekable_stream_decoder_set_md5_checking(decoder, true); + * [... other settings ...] + * FLAC__seekable_stream_decoder_set_read_callback(decoder, my_read_callback); + * FLAC__seekable_stream_decoder_set_seek_callback(decoder, my_seek_callback); + * FLAC__seekable_stream_decoder_set_tell_callback(decoder, my_tell_callback); + * FLAC__seekable_stream_decoder_set_length_callback(decoder, my_length_callback); + * FLAC__seekable_stream_decoder_set_eof_callback(decoder, my_eof_callback); + * FLAC__seekable_stream_decoder_set_write_callback(decoder, my_write_callback); + * FLAC__seekable_stream_decoder_set_metadata_callback(decoder, my_metadata_callback); + * FLAC__seekable_stream_decoder_set_error_callback(decoder, my_error_callback); + * FLAC__seekable_stream_decoder_set_client_data(decoder, my_client_data); + * if(FLAC__seekable_stream_decoder_init(decoder) != FLAC__SEEKABLE_STREAM_DECODER_OK) do_something; + * \endcode + * + * In FLAC 1.1.3 it is like this: + * + * \code + * FLAC__StreamDecoder *decoder = FLAC__stream_decoder_new(); + * if(decoder == NULL) do_something; + * FLAC__stream_decoder_set_md5_checking(decoder, true); + * [... other settings ...] + * if(FLAC__stream_decoder_init_stream( + * decoder, + * my_read_callback, + * my_seek_callback, // or NULL + * my_tell_callback, // or NULL + * my_length_callback, // or NULL + * my_eof_callback, // or NULL + * my_write_callback, + * my_metadata_callback, // or NULL + * my_error_callback, + * my_client_data + * ) != FLAC__STREAM_DECODER_INIT_STATUS_OK) do_something; + * \endcode + * + * or you could do; + * + * \code + * [...] + * FILE *file = fopen("somefile.flac","rb"); + * if(file == NULL) do_somthing; + * if(FLAC__stream_decoder_init_FILE( + * decoder, + * file, + * my_write_callback, + * my_metadata_callback, // or NULL + * my_error_callback, + * my_client_data + * ) != FLAC__STREAM_DECODER_INIT_STATUS_OK) do_something; + * \endcode + * + * or just: + * + * \code + * [...] + * if(FLAC__stream_decoder_init_file( + * decoder, + * "somefile.flac", + * my_write_callback, + * my_metadata_callback, // or NULL + * my_error_callback, + * my_client_data + * ) != FLAC__STREAM_DECODER_INIT_STATUS_OK) do_something; + * \endcode + * + * Another small change to the decoder is in how it handles unparseable + * streams. Before, when the decoder found an unparseable stream + * (reserved for when the decoder encounters a stream from a future + * encoder that it can't parse), it changed the state to + * \c FLAC__STREAM_DECODER_UNPARSEABLE_STREAM. Now the decoder instead + * drops sync and calls the error callback with a new error code + * \c FLAC__STREAM_DECODER_ERROR_STATUS_UNPARSEABLE_STREAM. This is + * more robust. If your error callback does not discriminate on the the + * error state, your code does not need to be changed. + * + * The encoder now has a new setting: + * FLAC__stream_encoder_set_apodization(). This is for setting the + * method used to window the data before LPC analysis. You only need to + * add a call to this function if the default is not suitable. There + * are also two new convenience functions that may be useful: + * FLAC__metadata_object_cuesheet_calculate_cddb_id() and + * FLAC__metadata_get_cuesheet(). + * + * The \a bytes parameter to FLAC__StreamDecoderReadCallback, + * FLAC__StreamEncoderReadCallback, and FLAC__StreamEncoderWriteCallback + * is now \c size_t instead of \c uint32_t. + */ + +/** \defgroup porting_1_1_3_to_1_1_4 Porting from FLAC 1.1.3 to 1.1.4 + * \ingroup porting + * + * \brief + * This module describes porting from FLAC 1.1.3 to FLAC 1.1.4. + * + * There were no changes to any of the interfaces from 1.1.3 to 1.1.4. + * There was a slight change in the implementation of + * FLAC__stream_encoder_set_metadata(); the function now makes a copy + * of the \a metadata array of pointers so the client no longer needs + * to maintain it after the call.

The function is now renamed and properly integrated as + * FLAC__stream_decoder_get_client_data + * + * To accomodate encoding and decoding 32-bit int PCM, some data types + * in the \b FLAC__frame struct were changed. Specifically, warmup + * in both the FLAC__Subframe_Fixed struc and the FLAC__Subframe_LPC + * struct is changed from FLAC__int32 to FLAC__int64. Also, value + * in the FLAC__Subframe_Constant is changed from FLAC__int32 to + * FLAC__int64. Finally, in FLAC__Subframe_Verbatim struct data is + * changes from a FLAC__int32 array to a union containing a FLAC__int32 + * array and a FLAC__int64 array. Also, a new member is added, + * data_type, which clarifies whether the FLAC__int32 or FLAC__int64 + * array is in use. + * + * Furthermore, the following functions now return the object untouched + * if memory allocation fails, whereas previously the handling varied + * and was more or less undefined + * + * - FLAC__metadata_object_seektable_resize_points + * - FLAC__metadata_object_vorbiscomment_resize_comments + * - FLAC__metadata_object_cuesheet_track_resize_indices + * - FLAC__metadata_object_cuesheet_resize_tracks + * + * The last breaking change is that all API functions taking a filename + * as an argument now, on Windows, must be supplied with that filename + * in the UTF-8 character encoding instead of using the current code + * page. libFLAC internally translates these UTF-8 encoded filenames to + * an appropriate representation to use with _wfopen.

This level is write- + * efficient in most cases (more on this below), and uses less memory + * than level 2. + * + * Level 2: + * Read-write access to all metadata blocks. This level is write- + * efficient in all cases, but uses more memory since all metadata for + * the whole file is read into memory and manipulated before writing + * out again. + * + * What do we mean by efficient? Since FLAC metadata appears at the + * beginning of the file, when writing metadata back to a FLAC file + * it is possible to grow or shrink the metadata such that the entire + * file must be rewritten. However, if the size remains the same during + * changes or PADDING blocks are utilized, only the metadata needs to be + * overwritten, which is much faster. + * + * Efficient means the whole file is rewritten at most one time, and only + * when necessary. Level 1 is not efficient only in the case that you + * cause more than one metadata block to grow or shrink beyond what can + * be accommodated by padding. In this case you should probably use level + * 2, which allows you to edit all the metadata for a file in memory and + * write it out all at once. + * + * All levels know how to skip over and not disturb an ID3v2 tag at the + * front of the file. + * + * All levels access files via their filenames. In addition, level 2 + * has additional alternative read and write functions that take an I/O + * handle and callbacks, for situations where access by filename is not + * possible. + * + * In addition to the three interfaces, this module defines functions for + * creating and manipulating various metadata objects in memory. As we see + * from the Format module, FLAC metadata blocks in memory are very primitive + * structures for storing information in an efficient way. Reading + * information from the structures is easy but creating or modifying them + * directly is more complex. The metadata object routines here facilitate + * this by taking care of the consistency and memory management drudgery. + * + * Unless you will be using the level 1 or 2 interfaces to modify existing + * metadata however, you will not probably not need these. + * + * From a dependency standpoint, none of the encoders or decoders require + * the metadata module.

Some (like + * seeking) are optional, depending on the capabilities of the input. + * + * For decoding directly from a file, use FLAC__stream_decoder_init_FILE() + * or FLAC__stream_decoder_init_file(). Then you must only supply an open + * \c FILE* or filename and fewer callbacks; the decoder will handle + * the other callbacks internally. + * + * There are three similarly-named init functions for decoding from Ogg + * FLAC streams. Check \c FLAC_API_SUPPORTS_OGG_FLAC to find out if the + * library has been built with Ogg support. + * + * Once the decoder is initialized, your program will call one of several + * functions to start the decoding process: + * + * - FLAC__stream_decoder_process_single() - Tells the decoder to process at + * most one metadata block or audio frame and return, calling either the + * metadata callback or write callback, respectively, once. If the decoder + * loses sync it will return with only the error callback being called. + * - FLAC__stream_decoder_process_until_end_of_metadata() - Tells the decoder + * to process the stream from the current location and stop upon reaching + * the first audio frame. The client will get one metadata, write, or error + * callback per metadata block, audio frame, or sync error, respectively. + * - FLAC__stream_decoder_process_until_end_of_stream() - Tells the decoder + * to process the stream from the current location until the read callback + * returns FLAC__STREAM_DECODER_READ_STATUS_END_OF_STREAM or + * FLAC__STREAM_DECODER_READ_STATUS_ABORT. The client will get one metadata, + * write, or error callback per metadata block, audio frame, or sync error, + * respectively. + * + * When the decoder has finished decoding (normally or through an abort), + * the instance is finished by calling FLAC__stream_decoder_finish(), which + * ensures the decoder is in the correct state and frees memory. Then the + * instance may be deleted with FLAC__stream_decoder_delete() or initialized + * again to decode another stream. + * + * Seeking is exposed through the FLAC__stream_decoder_seek_absolute() method. + * At any point after the stream decoder has been initialized, the client can + * call this function to seek to an exact sample within the stream. + * Subsequently, the first time the write callback is called it will be + * passed a (possibly partial) block starting at that sample. + * + * If the client cannot seek via the callback interface provided, but still + * has another way of seeking, it can flush the decoder using + * FLAC__stream_decoder_flush() and start feeding data from the new position + * through the read callback. + * + * The stream decoder also provides MD5 signature checking. If this is + * turned on before initialization, FLAC__stream_decoder_finish() will + * report when the decoded MD5 signature does not match the one stored + * in the STREAMINFO block. MD5 checking is automatically turned off + * (until the next FLAC__stream_decoder_reset()) if there is no signature + * in the STREAMINFO block or when a seek is attempted. + * + * The FLAC__stream_decoder_set_metadata_*() functions deserve special + * attention. By default, the decoder only calls the metadata_callback for + * the STREAMINFO block. These functions allow you to tell the decoder + * explicitly which blocks to parse and return via the metadata_callback + * and/or which to skip. Use a FLAC__stream_decoder_set_metadata_respond_all(), + * FLAC__stream_decoder_set_metadata_ignore() ... or FLAC__stream_decoder_set_metadata_ignore_all(), + * FLAC__stream_decoder_set_metadata_respond() ... sequence to exactly specify + * which blocks to return. Remember that metadata blocks can potentially + * be big (for example, cover art) so filtering out the ones you don't + * use can reduce the memory requirements of the decoder. Also note the + * special forms FLAC__stream_decoder_set_metadata_respond_application(id) + * and FLAC__stream_decoder_set_metadata_ignore_application(id) for + * filtering APPLICATION blocks based on the application ID. + * + * STREAMINFO and SEEKTABLE blocks are always parsed and used internally, but + * they still can legally be filtered from the metadata_callback. + * + * \note + * The "set" functions may only be called when the decoder is in the + * state FLAC__STREAM_DECODER_UNINITIALIZED, i.e. after + * FLAC__stream_decoder_new() or FLAC__stream_decoder_finish(), but + * before FLAC__stream_decoder_init_*(). If this is the case they will + * return \c true, otherwise \c false. + * + * \note + * FLAC__stream_decoder_finish() resets all settings to the constructor + * defaults, including the callbacks. + * + * \{ + */ + + +/** State values for a FLAC__StreamDecoder + * + * The decoder's state can be obtained by calling FLAC__stream_decoder_get_state(). + */ +typedef enum { + + FLAC__STREAM_DECODER_SEARCH_FOR_METADATA = 0, + /**< The decoder is ready to search for metadata. */ + + FLAC__STREAM_DECODER_READ_METADATA, + /**< The decoder is ready to or is in the process of reading metadata. */ + + FLAC__STREAM_DECODER_SEARCH_FOR_FRAME_SYNC, + /**< The decoder is ready to or is in the process of searching for the + * frame sync code. + */ + + FLAC__STREAM_DECODER_READ_FRAME, + /**< The decoder is ready to or is in the process of reading a frame. */ + + FLAC__STREAM_DECODER_END_OF_STREAM, + /**< The decoder has reached the end of the stream. */ + + FLAC__STREAM_DECODER_OGG_ERROR, + /**< An error occurred in the underlying Ogg layer. */ + + FLAC__STREAM_DECODER_SEEK_ERROR, + /**< An error occurred while seeking.

At a minimum, the following + * functions should be called: + * - FLAC__stream_encoder_set_channels() + * - FLAC__stream_encoder_set_bits_per_sample() + * - FLAC__stream_encoder_set_sample_rate() + * - FLAC__stream_encoder_set_ogg_serial_number() (if encoding to Ogg FLAC) + * - FLAC__stream_encoder_set_total_samples_estimate() (if known) + * - If the application wants to control the compression level or set its own + * metadata, then the following should also be called: + * - FLAC__stream_encoder_set_compression_level() + * - FLAC__stream_encoder_set_verify() + * - FLAC__stream_encoder_set_metadata() + * - The rest of the set functions should only be called if the client needs + * exact control over how the audio is compressed; thorough understanding + * of the FLAC format is necessary to achieve good results. + * - The program initializes the instance to validate the settings and + * prepare for encoding using + * - FLAC__stream_encoder_init_stream() or FLAC__stream_encoder_init_FILE() + * or FLAC__stream_encoder_init_file() for native FLAC + * - FLAC__stream_encoder_init_ogg_stream() or FLAC__stream_encoder_init_ogg_FILE() + * or FLAC__stream_encoder_init_ogg_file() for Ogg FLAC + * - The program calls FLAC__stream_encoder_process() or + * FLAC__stream_encoder_process_interleaved() to encode data, which + * subsequently calls the callbacks when there is encoder data ready + * to be written. + * - The program finishes the encoding with FLAC__stream_encoder_finish(), + * which causes the encoder to encode any data still in its input pipe, + * update the metadata with the final encoding statistics if output + * seeking is possible, and finally reset the encoder to the + * uninitialized state. + * - The instance may be used again or deleted with + * FLAC__stream_encoder_delete(). + * + * In more detail, the stream encoder functions similarly to the + * \link flac_stream_decoder stream decoder \endlink, but has fewer + * callbacks and more options. Typically the client will create a new + * instance by calling FLAC__stream_encoder_new(), then set the necessary + * parameters with FLAC__stream_encoder_set_*(), and initialize it by + * calling one of the FLAC__stream_encoder_init_*() functions. + * + * Unlike the decoders, the stream encoder has many options that can + * affect the speed and compression ratio. When setting these parameters + * you should have some basic knowledge of the format (see the + * user-level documentation + * or the formal description). The + * FLAC__stream_encoder_set_*() functions themselves do not validate the + * values as many are interdependent. The FLAC__stream_encoder_init_*() + * functions will do this, so make sure to pay attention to the state + * returned by FLAC__stream_encoder_init_*() to make sure that it is + * FLAC__STREAM_ENCODER_INIT_STATUS_OK. Any parameters that are not set + * before FLAC__stream_encoder_init_*() will take on the defaults from + * the constructor. + * + * There are three initialization functions for native FLAC, one for + * setting up the encoder to encode FLAC data to the client via + * callbacks, and two for encoding directly to a file. + * + * For encoding via callbacks, use FLAC__stream_encoder_init_stream(). + * You must also supply a write callback which will be called anytime + * there is raw encoded data to write. If the client can seek the output + * it is best to also supply seek and tell callbacks, as this allows the + * encoder to go back after encoding is finished to write back + * information that was collected while encoding, like seek point offsets, + * frame sizes, etc. + * + * For encoding directly to a file, use FLAC__stream_encoder_init_FILE() + * or FLAC__stream_encoder_init_file(). Then you must only supply a + * filename or open \c FILE*; the encoder will handle all the callbacks + * internally. You may also supply a progress callback for periodic + * notification of the encoding progress. + * + * There are three similarly-named init functions for encoding to Ogg + * FLAC streams. Check \c FLAC_API_SUPPORTS_OGG_FLAC to find out if the + * library has been built with Ogg support. + * + * The call to FLAC__stream_encoder_init_*() currently will also immediately + * call the write callback several times, once with the \c fLaC signature, + * and once for each encoded metadata block. Note that for Ogg FLAC + * encoding you will usually get at least twice the number of callbacks than + * with native FLAC, one for the Ogg page header and one for the page body. + * + * After initializing the instance, the client may feed audio data to the + * encoder in one of two ways: + * + * - Channel separate, through FLAC__stream_encoder_process() - The client + * will pass an array of pointers to buffers, one for each channel, to + * the encoder, each of the same length. The samples need not be + * block-aligned, but each channel should have the same number of samples. + * - Channel interleaved, through + * FLAC__stream_encoder_process_interleaved() - The client will pass a single + * pointer to data that is channel-interleaved (i.e. channel0_sample0, + * channel1_sample0, ... , channelN_sample0, channel0_sample1, ...). + * Again, the samples need not be block-aligned but they must be + * sample-aligned, i.e. the first value should be channel0_sample0 and + * the last value channelN_sampleM. + * + * Note that for either process call, each sample in the buffers should be a + * signed integer, right-justified to the resolution set by + * FLAC__stream_encoder_set_bits_per_sample(). For example, if the resolution + * is 16 bits per sample, the samples should all be in the range [-32768,32767]. + * + * When the client is finished encoding data, it calls + * FLAC__stream_encoder_finish(), which causes the encoder to encode any + * data still in its input pipe, and call the metadata callback with the + * final encoding statistics. Then the instance may be deleted with + * FLAC__stream_encoder_delete() or initialized again to encode another + * stream. + * + * For programs that write their own metadata, but that do not know the + * actual metadata until after encoding, it is advantageous to instruct + * the encoder to write a PADDING block of the correct size, so that + * instead of rewriting the whole stream after encoding, the program can + * just overwrite the PADDING block. If only the maximum size of the + * metadata is known, the program can write a slightly larger padding + * block, then split it after encoding. + * + * Make sure you understand how lengths are calculated. All FLAC metadata + * blocks have a 4 byte header which contains the type and length. This + * length does not include the 4 bytes of the header. See the format page + * for the specification of metadata blocks and their lengths. + * + * \note + * If you are writing the FLAC data to a file via callbacks, make sure it + * is open for update (e.g. mode "w+" for stdio streams). This is because + * after the first encoding pass, the encoder will try to seek back to the + * beginning of the stream, to the STREAMINFO block, to write some data + * there. (If using FLAC__stream_encoder_init*_file() or + * FLAC__stream_encoder_init*_FILE(), the file is managed internally.) + * + * \note + * The "set" functions may only be called when the encoder is in the + * state FLAC__STREAM_ENCODER_UNINITIALIZED, i.e. after + * FLAC__stream_encoder_new() or FLAC__stream_encoder_finish(), but + * before FLAC__stream_encoder_init_*().

Since you will not know + * the values for the seek point stream offsets, you should pass in + * a SEEKTABLE 'template', that is, a SEEKTABLE object with the + * required sample numbers (or placeholder points), with \c 0 for the + * \a frame_samples and \a stream_offset fields for each point. If the + * client has specified that it supports seeking by providing a seek + * callback to FLAC__stream_encoder_init_stream() or both seek AND read + * callback to FLAC__stream_encoder_init_ogg_stream() (or by using + * FLAC__stream_encoder_init*_file() or FLAC__stream_encoder_init*_FILE()), + * then while it is encoding the encoder will fill the stream offsets in + * for you and when encoding is finished, it will seek back and write the + * real values into the SEEKTABLE block in the stream. There are helper + * routines for manipulating seektable template blocks; see metadata.h: + * FLAC__metadata_object_seektable_template_*(). If the client does + * not support seeking, the SEEKTABLE will have inaccurate offsets which + * will slow down or remove the ability to seek in the FLAC stream. + * + * \note + * The encoder instance \b will modify the first \c SEEKTABLE block + * as it transforms the template to a valid seektable while encoding, + * but it is still up to the caller to free all metadata blocks after + * encoding. + * + * \note + * A VORBIS_COMMENT block may be supplied. The vendor string in it + * will be ignored. libFLAC will use it's own vendor string. libFLAC + * will not modify the passed-in VORBIS_COMMENT's vendor string, it + * will simply write it's own into the stream. If no VORBIS_COMMENT + * block is present in the \a metadata array, libFLAC will write an + * empty one, containing only the vendor string. + * + * \note The Ogg FLAC mapping requires that the VORBIS_COMMENT block be + * the second metadata block of the stream. The encoder already supplies + * the STREAMINFO block automatically. If \a metadata does not contain a + * VORBIS_COMMENT block, the encoder will supply that too. Otherwise, if + * \a metadata does contain a VORBIS_COMMENT block and it is not the + * first, the init function will reorder \a metadata by moving the + * VORBIS_COMMENT block to the front; the relative ordering of the other + * blocks will remain as they were. + * + * \note The Ogg FLAC mapping limits the number of metadata blocks per + * stream to \c 65535.

Encoding is the default +invocation, but can be switch to decoding with **-d**, analysis with +**-a** or testing with **-t**. Depending on which way is chosen, +encoding, decoding, analysis or testing options can be used, see section +OPTIONS for details. General options can be used for all. + +If only one inputfile is specified, it may be "-" for stdin. When stdin +is used as input, flac will write to stdout. Otherwise flac will perform +the desired operation on each input file to similarly named output files +(meaning for encoding, the extension will be replaced with ".flac", or +appended with ".flac" if the input file has no extension, and for +decoding, the extension will be ".wav" for WAVE output and ".raw" for raw +output). The original file is not deleted unless --delete-input-file is +specified. + +If you are encoding/decoding from stdin to a file, you should use the -o +option like so: + + flac [options] -o outputfile + flac -d [options] -o outputfile + +which are better than: + + flac [options] > outputfile + flac -d [options] > outputfile + +since the former allows flac to seek backwards to write the STREAMINFO or +RIFF WAVE header contents when necessary. + +Also, you can force output data to go to stdout using -c. + +To encode or decode files that start with a dash, use -- to signal the +end of options, to keep the filenames themselves from being treated as +options: + + flac -V -- -01-filename.wav + +The encoding options affect the compression ratio and encoding speed. The +format options are used to tell flac the arrangement of samples if the +input file (or output file when decoding) is a raw file. If it is a RIFF +WAVE, Wave64, RF64, or AIFF file the format options are not needed since +they are read from the file's header. + +In test mode, flac acts just like in decode mode, except no output file +is written. Both decode and test modes detect errors in the stream, but +they also detect when the MD5 signature of the decoded audio does not +match the stored MD5 signature, even when the bitstream is valid. + +flac can also re-encode FLAC files. In other words, you can specify a +FLAC or Ogg FLAC file as an input to the encoder and it will decoder it +and re-encode it according to the options you specify. It will also +preserve all the metadata unless you override it with other options (e.g. +specifying new tags, seekpoints, cuesheet, padding, etc.). + +flac has been tuned so that the default settings yield a good speed vs. +compression tradeoff for many kinds of input. However, if you are looking +to maximize the compression rate or speed, or want to use the full power +of FLAC's metadata system, see the page titled 'About the FLAC Format' on +the FLAC website. + +# EXAMPLES + +Some common **encoding** tasks using flac: + +`flac abc.wav` +: Encode abc.wav to abc.flac using the default compression setting. abc.wav is not deleted. + +`flac --delete-input-file abc.wav` +: Like above, except abc.wav is deleted if there were no errors. + +`flac --delete-input-file -w abc.wav` +: Like above, except abc.wav is deleted if there were no errors or warnings. + +`flac --best abc.wav` +: Encode abc.wav to abc.flac using the highest compression setting. + +`flac --verify abc.wav` +: Encode abc.wav to abc.flac and internally decode abc.flac to make sure it matches abc.wav. + +`flac -o my.flac abc.wav` +: Encode abc.wav to my.flac. + +`flac -T "TITLE=Bohemian Rhapsody" -T "ARTIST=Queen" abc.wav` +: Encode abc.wav and add some tags at the same time to abc.flac. + +`flac *.wav` +: Encode all .wav files in the current directory. + +`flac abc.aiff` +: Encode abc.aiff to abc.flac. + +`flac abc.rf64` +: Encode abc.rf64 to abc.flac. + +`flac abc.w64` +: Encode abc.w64 to abc.flac. + +`flac abc.flac --force` +: This one's a little tricky: notice that flac is in encode mode by + default (you have to specify -d to decode) so this command actually + recompresses abc.flac back to abc.flac. --force is needed to make + sure you really want to overwrite abc.flac with a new version. Why + would you want to do this? It allows you to recompress an existing + FLAC file with (usually) higher compression options or a newer + version of FLAC and preserve all the metadata like tags too. + +Some common **decoding** tasks using flac: + +`flac -d abc.flac` +: Decode abc.flac to abc.wav. abc.flac is not deleted. NOTE: Without + -d it means re-encode abc.flac to abc.flac (see above). + +`flac -d --force-aiff-format abc.flac` +`flac -d -o abc.aiff abc.flac` +: Two different ways of decoding abc.flac to abc.aiff (AIFF format). + abc.flac is not deleted. + +`flac -d --force-rf64-format abc.flac` +`flac -d -o abc.rf64 abc.flac` +: Two different ways of decoding abc.flac to abc.rf64 (RF64 format). + abc.flac is not deleted. + +`flac -d --force-wave64-format abc.flac` +`flac -d -o abc.w64 abc.flac` +: Two different ways of decoding abc.flac to abc.w64 (Wave64 format). + abc.flac is not deleted. + +`flac -d -F abc.flac` +: Decode abc.flac to abc.wav and don't abort if errors are found + (useful for recovering as much as possible from corrupted files). + + +# OPTIONS + +A summary of options is included below. For a complete description, see +the HTML documentation. + +## GENERAL OPTIONS + +**-v, \--version** +: Show the flac version number + +**-h, \--help** +: Show basic usage and a list of all options + +**-H, \--explain** +: Show detailed explanation of usage and all options + +**-d, \--decode** +: Decode (the default behavior is to encode) + +**-t, \--test** +: Test a flac encoded file (same as -d except no decoded file is written) + +**-a, \--analyze** +: Analyze a FLAC encoded file (same as -d except an analysis file is + written) + +**-c, \--stdout** +: Write output to stdout + +**-s, \--silent** +: Silent mode (do not write runtime encode/decode statistics to stderr) + +**\--totally-silent** +: Do not print anything of any kind, including warnings or errors. The + exit code will be the only way to determine successful completion. + +**\--no-utf8-convert** +: Do not convert tags from local charset to UTF-8. This is useful for + scripts, and setting tags in situations where the locale is wrong. + This option must appear before any tag options! + +**-w, \--warnings-as-errors** +: Treat all warnings as errors (which cause flac to terminate with a + non-zero exit code). + +**-f, \--force** +: Force overwriting of output files. By default, flac warns that the + output file already exists and continues to the next file. + +**-o** *filename***, \--output-name=***filename* +: Force the output file name (usually flac just changes the extension). + May only be used when encoding a single file. May not be used in + conjunction with \--output-prefix. + +**\--output-prefix=***string* +: Prefix each output file name with the given string. This can be + useful for encoding or decoding files to a different directory. Make + sure if your string is a path name that it ends with a trailing \`/' + (slash). + +**\--delete-input-file** +: Automatically delete the input file after a successful encode or + decode. If there was an error (including a verify error) the input + file is left intact. + +**\--preserve-modtime** +: Output files have their timestamps/permissions set to match those of + their inputs (this is default). Use \--no-preserve-modtime to make + output files have the current time and default permissions. + +**\--keep-foreign-metadata** +: If encoding, save WAVE, RF64, or AIFF non-audio chunks in FLAC + metadata. If decoding, restore any saved non-audio chunks from FLAC + metadata when writing the decoded file. Foreign metadata cannot be + transcoded, e.g. WAVE chunks saved in a FLAC file cannot be restored + when decoding to AIFF. Input and output must be regular files (not + stdin or stdout). With this option, FLAC will pick the right output + format on decoding. + +**\--keep-foreign-metadata-if-present** +: Like \--keep-foreign-metadata, but without throwing an error if + foreign metadata cannot be found or restored, instead printing a + warning. + +**\--skip={***\#***\|***mm:ss.ss***}** +: Skip over the first number of samples of the input. This works for + both encoding and decoding, but not testing. The alternative form + mm:ss.ss can be used to specify minutes, seconds, and fractions of a + second. + +**\--until={***\#***\|\[***+***\|***-***\]***mm:ss.ss***}** +: Stop at the given sample number for each input file. This works for + both encoding and decoding, but not testing. The given sample number + is not included in the decoded output. The alternative form mm:ss.ss + can be used to specify minutes, seconds, and fractions of a second. + If a \`+' (plus) sign is at the beginning, the \--until point is + relative to the \--skip point. If a \`-' (minus) sign is at the + beginning, the \--until point is relative to end of the audio. + +**\--ogg** +: When encoding, generate Ogg FLAC output instead of native FLAC. Ogg + FLAC streams are FLAC streams wrapped in an Ogg transport layer. The + resulting file should have an '.oga' extension and will still be + decodable by flac. When decoding, force the input to be treated as + Ogg FLAC. This is useful when piping input from stdin or when the + filename does not end in '.oga' or '.ogg'. + +**\--serial-number=***\#* +: When used with \--ogg, specifies the serial number to use for the + first Ogg FLAC stream, which is then incremented for each additional + stream. When encoding and no serial number is given, flac uses a + random number for the first stream, then increments it for each + additional stream. When decoding and no number is given, flac uses + the serial number of the first page. + +## ANALYSIS OPTIONS + +**\--residual-text** +: Includes the residual signal in the analysis file. This will make the + file very big, much larger than even the decoded file. + +**\--residual-gnuplot** +: Generates a gnuplot file for every subframe; each file will contain + the residual distribution of the subframe. This will create a lot of + files. + +## DECODING OPTIONS + +**\--cue=\[***\#.#***\]\[-\[***\#.#***\]\]** +: Set the beginning and ending cuepoints to decode. The optional first + \#.# is the track and index point at which decoding will start; the + default is the beginning of the stream. The optional second \#.# is + the track and index point at which decoding will end; the default is + the end of the stream. If the cuepoint does not exist, the closest + one before it (for the start point) or after it (for the end point) + will be used. If those don't exist, the start of the stream (for the + start point) or end of the stream (for the end point) will be used. + The cuepoints are merely translated into sample numbers then used as + \--skip and \--until. A CD track can always be cued by, for example, + \--cue=9.1-10.1 for track 9, even if the CD has no 10th track. + +**-F, \--decode-through-errors** +: By default flac stops decoding with an error and removes the + partially decoded file if it encounters a bitstream error. With -F, + errors are still printed but flac will continue decoding to + completion. Note that errors may cause the decoded audio to be + missing some samples or have silent sections. + +**\--apply-replaygain-which-is-not-lossless\[=\\]** +: Applies ReplayGain values while decoding. **WARNING: THIS IS NOT + LOSSLESS. DECODED AUDIO WILL NOT BE IDENTICAL TO THE ORIGINAL WITH + THIS OPTION.** This option is useful for example in transcoding + media servers, where the client does not support ReplayGain. For + details on the use of this option, see the section **ReplayGain + application specification**. + +## ENCODING OPTIONS + +**-V, \--verify** +: Verify a correct encoding by decoding the output in parallel and + comparing to the original + +**\--lax** +: Allow encoder to generate non-Subset files. The resulting FLAC file + may not be streamable or might have trouble being played in all + players (especially hardware devices), so you should only use this + option in combination with custom encoding options meant for + archival. + +**\--replay-gain** +: Calculate ReplayGain values and store them as FLAC tags, similar to + vorbisgain. Title gains/peaks will be computed for each input file, + and an album gain/peak will be computed for all files. All input + files must have the same resolution, sample rate, and number of + channels. Only mono and stereo files are allowed, and the sample + rate must be 8, 11.025, 12, 16, 18.9, 22.05, 24, 28, 32, 36, 37.8, + 44.1, 48, 56, 64, 72, 75.6, 88.2, 96, 112, 128, 144, 151.2, 176.4, + 192, 224, 256, 288, 302.4, 352.8, 384, 448, 512, 576, or 604.8 kHz. + Also note that this option may leave a few extra bytes in a PADDING + block as the exact size of the tags is not known until all files + are processed. Note that this option cannot be used when encoding + to standard output (stdout). + +**\--cuesheet=***filename* +: Import the given cuesheet file and store it in a CUESHEET metadata + block. This option may only be used when encoding a single file. A + seekpoint will be added for each index point in the cuesheet to the + SEEKTABLE unless \--no-cued-seekpoints is specified. + +**\--picture={***FILENAME***\|***SPECIFICATION***}** +: Import a picture and store it in a PICTURE metadata block. More than + one \--picture option can be specified. Either a filename for the + picture file or a more complete specification form can be used. The + SPECIFICATION is a string whose parts are separated by \| (pipe) + characters. Some parts may be left empty to invoke default values. + FILENAME is just shorthand for "\|\|\|\|FILENAME". For the format of + SPECIFICATION, see the section **picture specification**. + +**\--ignore-chunk-sizes** +: When encoding to flac, ignore the file size headers in WAV and AIFF + files to attempt to work around problems with over-sized or malformed + files. WAV and AIFF files both have an unsigned 32 bit numbers in + the file header which specifes the length of audio data. Since this + number is unsigned 32 bits, that limits the size of a valid file to + being just over 4 Gigabytes. Files larger than this are mal-formed, + but should be read correctly using this option. + +**-S {***\#***\|***X***\|***\#x***\|***\#s***}, \--seekpoint={***\#***\|***X***\|***\#x***\|***\#s***}** +: Include a point or points in a SEEKTABLE. Using \#, a seek point at + that sample number is added. Using X, a placeholder point is added at + the end of a the table. Using \#x, \# evenly spaced seek points will + be added, the first being at sample 0. Using \#s, a seekpoint will be + added every \# seconds (# does not have to be a whole number; it can + be, for example, 9.5, meaning a seekpoint every 9.5 seconds). You may + use many -S options; the resulting SEEKTABLE will be the unique-ified + union of all such values. With no -S options, flac defaults to + '-S 10s'. Use \--no-seektable for no SEEKTABLE. Note: '-S \#x' and + '-S \#s' will not work if the encoder can't determine the input size + before starting. Note: if you use '-S \#' and \# is \>= samples in + the input, there will be either no seek point entered (if the input + size is determinable before encoding starts) or a placeholder point + (if input size is not determinable). + +**-P** *\#***, \--padding=***\#* +: Tell the encoder to write a PADDING metadata block of the given + length (in bytes) after the STREAMINFO block. This is useful if you + plan to tag the file later with an APPLICATION block; instead of + having to rewrite the entire file later just to insert your block, + you can write directly over the PADDING block. Note that the total + length of the PADDING block will be 4 bytes longer than the length + given because of the 4 metadata block header bytes. You can force no + PADDING block at all to be written with \--no-padding. The encoder + writes a PADDING block of 8192 bytes by default (or 65536 bytes if + the input audio stream is more that 20 minutes long). + +**-T** *FIELD=VALUE***, \--tag=***FIELD=VALUE* +: Add a FLAC tag. The comment must adhere to the Vorbis comment spec; + i.e. the FIELD must contain only legal characters, terminated by an + 'equals' sign. Make sure to quote the comment if necessary. This + option may appear more than once to add several comments. NOTE: all + tags will be added to all encoded files. + +**\--tag-from-file=***FIELD=FILENAME* +: Like \--tag, except FILENAME is a file whose contents will be read + verbatim to set the tag value. The contents will be converted to + UTF-8 from the local charset. This can be used to store a cuesheet + in a tag (e.g. \--tag-from-file="CUESHEET=image.cue"). Do not try to + store binary data in tag fields! Use APPLICATION blocks for that. + +**-b** *\#***, \--blocksize=***\#* +: Specify the blocksize in samples. The default is 1152 for -l 0, + else 4096. For subset streams this must be \<= 4608 if the samplerate + \<= 48kHz, for subset streams with higher samplerates it must be \<= + 16384. + +**-m, \--mid-side** +: Try mid-side coding for each frame (stereo input only) + +**-M, \--adaptive-mid-side** +: Adaptive mid-side coding for all frames (stereo input only) + +**-0..-8, \--compression-level-0..\--compression-level-8** +: Fastest compression..highest compression (default is -5). These are + synonyms for other options: + +**-0, \--compression-level-0** +: Synonymous with -l 0 -b 1152 -r 3 \--no-mid-side + +**-1, \--compression-level-1** +: Synonymous with -l 0 -b 1152 -M -r 3 + +**-2, \--compression-level-2** +: Synonymous with -l 0 -b 1152 -m -r 3 + +**-3, \--compression-level-3** +: Synonymous with -l 6 -b 4096 -r 4 \--no-mid-side + +**-4, \--compression-level-4** +: Synonymous with -l 8 -b 4096 -M -r 4 + +**-5, \--compression-level-5** +: Synonymous with -l 8 -b 4096 -m -r 5 + +**-6, \--compression-level-6** +: Synonymous with -l 8 -b 4096 -m -r 6 -A subdivide_tukey(2) + +**-7, \--compression-level-7** +: Synonymous with -l 12 -b 4096 -m -r 6 -A subdivide_tukey(2) + +**-8, \--compression-level-8** +: Synonymous with -l 12 -b 4096 -m -r 6 -A subdivide_tukey(3) + +**\--fast** +: Fastest compression. Currently synonymous with -0. + +**\--best** +: Highest compression. Currently synonymous with -8. + +**-e, \--exhaustive-model-search** +: Do exhaustive model search (expensive!) + +**-A** *function***, \--apodization=***function* +: Window audio data with given the apodization function. See section + **Apodization functions** for details. + +**-l** *\#***, \--max-lpc-order=***\#* +: Specifies the maximum LPC order. This number must be \<= 32. For + subset streams, it must be \<=12 if the sample rate is \<=48kHz. If + 0, the encoder will not attempt generic linear prediction, and use + only fixed predictors. Using fixed predictors is faster but usually + results in files being 5-10% larger. + +**-p, \--qlp-coeff-precision-search** +: Do exhaustive search of LP coefficient quantization (expensive!). + Overrides -q; does nothing if using -l 0 + +**-q** *\#***, \--qlp-coeff-precision=***\#* +: Precision of the quantized linear-predictor coefficients, 0 =\> let + encoder decide (min is 5, default is 0) + +**-r \[***\#***,\]***\#***, \--rice-partition-order=\[***\#***,\]***\#* +: Set the \[min,\]max residual partition order (0..15). min defaults to + 0 if unspecified. Default is -r 5. + +## FORMAT OPTIONS + +**\--endian={***big***\|***little***}** +: Set the byte order for samples + +**\--channels=***\#* +: Set number of channels. + +**\--bps=***\#* +: Set bits per sample. + +**\--sample-rate=***\#* +: Set sample rate (in Hz). + +**\--sign={***signed***\|***unsigned***}** +: Set the sign of samples. + +**\--input-size=***\#* +: Specify the size of the raw input in bytes. If you are encoding raw + samples from stdin, you must set this option in order to be able to + use \--skip, \--until, \--cuesheet, or other options that need to + know the size of the input beforehand. If the size given is greater + than what is found in the input stream, the encoder will complain + about an unexpected end-of-file. If the size given is less, samples + will be truncated. + +**\--force-raw-format** +: Force input (when encoding) or output (when decoding) to be treated + as raw samples (even if filename ends in *.wav*). + +**\--force-aiff-format** +**\--force-rf64-format** +**\--force-wave64-format** +: Force the decoder to output AIFF/RF64/WAVE64 format respectively. + This option is not needed if the output filename (as set by -o) + ends with *.aif* or *.aiff*, *.rf64* and *.w64* respectively. Also, + this option has no effect when encoding since input is + auto-detected. When none of these options nor + --keep-foreign-metadata are given and no output filename is set, + the output format is WAV by default. + +**\--force-legacy-wave-format** +**\--force-extensible-wave-format** +: Instruct the decoder to output a WAVE file with WAVE_FORMAT_PCM and + WAVE_FORMAT_EXTENSIBLE respectively. If none of these options nor + --keep-foreign-metadata are given, FLAC outputs WAVE_FORMAT_PCM + for mono or stereo with a bit depth of 8 or 16 bits, and + WAVE_FORMAT_EXTENSIBLE for all other audio formats. + +**\--force-aiff-c-none-format** +**\--force-aiff-c-sowt-format** +: Instruct the decoder to output an AIFF-C file with format NONE and + sowt respectively. + +## NEGATIVE OPTIONS + +**\--no-adaptive-mid-side** +**\--no-cued-seekpoints** +**\--no-decode-through-errors** +**\--no-delete-input-file** +**\--no-preserve-modtime** +**\--no-keep-foreign-metadata** +**\--no-exhaustive-model-search** +**\--no-force** +**\--no-lax** +**\--no-mid-side** +**\--no-ogg** +**\--no-padding** +**\--no-qlp-coeff-prec-search** +**\--no-replay-gain** +**\--no-residual-gnuplot** +**\--no-residual-text** +**\--no-seektable** +**\--no-silent** +**\--no-verify** +**\--no-warnings-as-errors** + +These flags can be used to invert the sense of the corresponding normal +option. + +## ReplayGain application specification +The option \--apply-replaygain-which-is-not-lossless\[=\\]** +applies ReplayGain values while decoding. **WARNING: THIS IS NOT +LOSSLESS. DECODED AUDIO WILL NOT BE IDENTICAL TO THE ORIGINAL WITH THIS +OPTION.** This option is useful for example in transcoding media servers, +where the client does not support ReplayGain. + +The equals sign and \ is optional. If omitted, the +default specification is 0aLn1. + +The \ is a shorthand notation for describing how to apply +ReplayGain. All components are optional but order is important. '\[\]' +means 'optional'. '\|' means 'or'. '{}' means required. The format is: + +\[\\]\[a\|t\]\[l\|L\]\[n{0\|1\|2\|3}\] + +In which the following parameters are used: + +- **preamp**: A floating point number in dB. This is added to the + existing gain value. + +- **a\|t**: Specify 'a' to use the album gain, or 't' to use the track + gain. If tags for the preferred kind (album/track) do not exist but + tags for the other (track/album) do, those will be used instead. + +- **l\|L**: Specify 'l' to peak-limit the output, so that the + ReplayGain peak value is full-scale. Specify 'L' to use a 6dB hard + limiter that kicks in when the signal approaches full-scale. + +- **n{0\|1\|2\|3}**: Specify the amount of noise shaping. ReplayGain + synthesis happens in floating point; the result is dithered before + converting back to integer. This quantization adds noise. Noise + shaping tries to move the noise where you won't hear it as much. + 0 means no noise shaping, 1 means 'low', 2 means 'medium', 3 means + 'high'. + +For example, the default of 0aLn1 means 0dB preamp, use album gain, 6dB +hard limit, low noise shaping. \--apply-replaygain-which-is-not-lossless=3 +means 3dB preamp, use album gain, no limiting, no noise shaping. + +flac uses the ReplayGain tags for the calculation. If a stream does +not have the required tags or they can't be parsed, decoding will +continue with a warning, and no ReplayGain is applied to that stream. + +## Picture specification +This described the specification used for the **\--picture** option. +\[TYPE\]\|\[MIME-TYPE\]\|\[DESCRIPTION\]\|\[WIDTHxHEIGHTxDEPTH\[/COLORS\]\]\|FILE + +TYPE is optional; it is a number from one of: + +0.

You may perform one major operation, or many shorthand +operations at a time. + +# GENERAL USAGE + +metaflac is the command-line .flac file metadata editor. You can use it +to list the contents of metadata blocks, edit, delete or insert blocks, +and manage padding. + +metaflac takes a set of "options" (though some are not optional) and a +set of FLAC files to operate on. There are three kinds of "options": + +- Major operations, which specify a mode of operation like listing + blocks, removing blocks, etc. These will have sub-operations describing + exactly what is to be done. + +- Shorthand operations, which are convenient synonyms for major + operations. For example, there is a shorthand operation + --show-sample-rate that shows just the sample rate field from the + STREAMINFO metadata block. + +- Global options, which affect all the operations. + +All of these are described in the tables below. At least one shorthand +or major operation must be supplied. You can use multiple shorthand +operations to do more than one thing to a file or set of files. Most of +the common things to do to metadata have shorthand operations. As an +example, here is how to show the MD5 signatures for a set of three FLAC +files: + +`metaflac --show-md5sum file1.flac file2.flac file3.flac` + +Another example; this removes all DESCRIPTION and COMMENT tags in a set +of FLAC files, and uses the --preserve-modtime global option to keep the +FLAC file modification times the same (usually when files are edited the +modification time is set to the current time): + +`metaflac --preserve-modtime --remove-tag=DESCRIPTION --remove-tag=COMMENT file1.flac file2.flac file3.flac` + +# OPTIONS + +**\--preserve-modtime** +: Preserve the original modification time in spite of edits. + +**\--with-filename** +: Prefix each output line with the FLAC file name (the default if more + than one FLAC file is specified). This option has no effect for + options exporting to a file, like --export-tags-to. + +**\--no-filename** +: Do not prefix each output line with the FLAC file name (the default + if only one FLAC file is specified). + +**\--no-utf8-convert** +: Do not convert tags from UTF-8 to local charset, or vice versa. This + is useful for scripts, and setting tags in situations where the + locale is wrong. + +**\--dont-use-padding** +: By default metaflac tries to use padding where possible to avoid + rewriting the entire file if the metadata size changes. Use this + option to tell metaflac to not take advantage of padding this way. + +# SHORTHAND OPERATIONS + +**\--show-md5sum** +: Show the MD5 signature from the STREAMINFO block. + +**\--show-min-blocksize** +: Show the minimum block size from the STREAMINFO block. + +**\--show-max-blocksize** +: Show the maximum block size from the STREAMINFO block. + +**\--show-min-framesize** +: Show the minimum frame size from the STREAMINFO block. + +**\--show-max-framesize** +: Show the maximum frame size from the STREAMINFO block. + +**\--show-sample-rate** +: Show the sample rate from the STREAMINFO block. + +**\--show-channels** +: Show the number of channels from the STREAMINFO block. + +**\--show-bps** +: Show the \# of bits per sample from the STREAMINFO block. + +**\--show-total-samples** +: Show the total \# of samples from the STREAMINFO block. + +**\--show-vendor-tag** +: Show the vendor string from the VORBIS_COMMENT block. + +**\--show-tag=name** +: Show all tags where the field name matches 'name'. + +**\--show-all-tags** +: Show all tags. This is an alias for --export-tags-to=-. + +**\--remove-tag=name** +: Remove all tags whose field name is 'name'. + +**\--remove-first-tag=name** +: Remove first tag whose field name is 'name'. + +**\--remove-all-tags** +: Remove all tags, leaving only the vendor string. + +**\--remove-all-tags-except=NAME1\[=NAME2\[=...\]\]** +: Remove all tags, except the vendor string and the tag names + specified. Tag names must be separated by an = character. + +**\--set-tag=field** +: Add a tag. The field must comply with the Vorbis comment spec, of the + form "NAME=VALUE". If there is currently no tag block, one will be + created. + +**\--set-tag-from-file=field** +: Like \--set-tag, except the VALUE is a filename whose contents will + be read verbatim to set the tag value. Unless \--no-utf8-convert is + specified, the contents will be converted to UTF-8 from the local + charset. This can be used to store a cuesheet in a tag (e.g. + \--set-tag-from-file="CUESHEET=image.cue"). Do not try to store + binary data in tag fields! Use APPLICATION blocks for that. + +**\--import-tags-from=file** +: Import tags from a file. Use '-' for stdin. Each line should be of + the form NAME=VALUE. Multi-line comments are currently not supported. + Specify \--remove-all-tags and/or \--no-utf8-convert before + \--import-tags-from if necessary. If FILE is '-' (stdin), only one + FLAC file may be specified. + +**\--export-tags-to=file** +: Export tags to a file. Use '-' for stdout. Each line will be of the + form NAME=VALUE. Specify \--no-utf8-convert if necessary. + +**\--import-cuesheet-from=file** +: Import a cuesheet from a file. Use '-' for stdin. Only one FLAC file + may be specified. A seekpoint will be added for each index point in + the cuesheet to the SEEKTABLE unless \--no-cued-seekpoints is + specified. + +**\--export-cuesheet-to=file** +: Export CUESHEET block to a cuesheet file, suitable for use by CD + authoring software. Use '-' for stdout. Only one FLAC file may be + specified on the command line. + +**\--import-picture-from={***FILENAME***\|***SPECIFICATION***}** +: Import a picture and store it in a PICTURE metadata block. More than + one \--import-picture-from command can be specified. Either a filename + for the picture file or a more complete specification form can be + used. The SPECIFICATION is a string whose parts are separated by \| + (pipe) characters. Some parts may be left empty to invoke default + values. FILENAME is just shorthand for "\|\|\|\|FILENAME". For + details on the specification, see the section **Picture + specification** in the **flac(1)** man page. + +**\--export-picture-to=file** +: Export PICTURE block to a file. Use '-' for stdout. Only one FLAC + file may be specified on the command line. The first PICTURE block + will be exported unless \--export-picture-to is preceded by a + \--block-number=# option to specify the exact metadata block to + extract. Note that the block number is the one shown by \--list. + +**\--add-replay-gain** +: Calculates the title and album gains/peaks of the given FLAC files as + if all the files were part of one album, then stores them as FLAC + tags. The tags are the same as those used by vorbisgain. Existing + ReplayGain tags will be replaced. If only one FLAC file is given, + the album and title gains will be the same. Since this operation + requires two passes, it is always executed last, after all other + operations have been completed and written to disk. All FLAC files + specified must have the same resolution, sample rate, and number of + channels. Only mono and stereo files are allowed, and the sample + rate must be 8, 11.025, 12, 16, 18.9, 22.05, 24, 28, 32, 36, 37.8, + 44.1, 48, 56, 64, 72, 75.6, 88.2, 96, 112, 128, 144, 151.2, 176.4, + 192, 224, 256, 288, 302.4, 352.8, 384, 448, 512, 576, or 604.8 kHz. + +**\--scan-replay-gain** +: Like \--add-replay-gain, but only analyzes the files rather than + writing them to the tags. + +**\--remove-replay-gain** +: Removes the ReplayGain tags. + +**\--add-seekpoint={***\#***\|***X***\|***\#x***\|***\#s***}** +: Add seek points to a SEEKTABLE block. Using \#, a seek point at that + sample number is added. Using X, a placeholder point is added at the + end of a the table. Using \#x, \# evenly spaced seek points will be + added, the first being at sample 0. Using \#s, a seekpoint will be + added every \# seconds (# does not have to be a whole number; it can + be, for example, 9.5, meaning a seekpoint every 9.5 seconds). If no + SEEKTABLE block exists, one will be created. If one already exists, + points will be added to the existing table, and any duplicates will + be turned into placeholder points. You may use many \--add-seekpoint + options; the resulting SEEKTABLE will be the unique-ified union of + all such values. Example: \--add-seekpoint=100x \--add-seekpoint=3.5s + will add 100 evenly spaced seekpoints and a seekpoint every 3.5 + seconds. + +**\--add-padding=length** +: Add a padding block of the given length (in bytes). The overall + length of the new block will be 4 + length; the extra 4 bytes is for + the metadata block header. + +# MAJOR OPERATIONS + +**\--list** +: List the contents of one or more metadata blocks to stdout. By + default, all metadata blocks are listed in text format. Use the + options **\--block-number**, **\--block-type** or + **\--except-block-type** to change this behavior. + +**\--remove** +: Remove one or more metadata blocks from the metadata. Use the options + **\--block-number**, **\--block-type** or **\--except-block-type** + to specify which blocks should be removed. Note that if both + \--block-number and \--[except-]block-type are specified, the result + is the logical AND of both arguments. Unless \--dont-use-padding + is specified, the blocks will be replaced with padding. You may not + remove the STREAMINFO block. + +**\--block-number=#\[,#\[...\]\]** +: An optional comma-separated list of block numbers to display. The + first block, the STREAMINFO block, is block 0. + +**\--block-type=type\[,type\[...\]\]** + +**\--except-block-type=type\[,type\[...\]\]** +: An optional comma-separated list of block types to be included or + ignored with this option. Use only one of \--block-type or + \--except-block-type. The valid block types are: STREAMINFO, PADDING, + APPLICATION, SEEKTABLE, VORBIS_COMMENT, PICTURE. You may narrow down + the types of APPLICATION blocks selected by appending APPLICATION + with a colon and the ID of the APPLICATION block in either ASCII + or hexadecimal representation. E.g. APPLICATION:abcd for the + APPLICATION block(s) whose textual representation of the 4-byte ID + is "abcd" or APPLICATION:0xXXXXXXXX for the APPLICATION block(s) + whose hexadecimal big- endian representation of the 4-byte ID + is "0xXXXXXXXX". For the example "abcd" above the hexadecimal + equivalalent is 0x61626364 + +**\--application-data-format=hexdump\|text** +: If the application block you are displaying contains binary data but + your \--data-format=text, you can display a hex dump of the + application data contents instead using + \--application-data-format=hexdump. + +**\--data-format=binary\|binary-headerless\|text** +: For use with --list. By default a human-readable text + representation of the data is isplayed. You may specify + --data-format=binary to dump the raw binary form of each metadata + block. Specify --data-format=binary-headerless to omit output of + metadata block headers, including the id of APPLICATION metadata + blocks. + +**\--append** +: Insert a metadata block from a file. This must be a binary block as + exported with --list --data-format=binary. The insertion point is + defined with --block-number=#. The new block will be added after the + given block number. This prevents the illegal insertion of a block + before the first STREAMINFO block. You may not --append another + STREAMINFO block. It is possible to copy a metadata block from one + file to another with this option. For example use + `metaflac --list --data-format=binary --block-number=6 file.flac > block` + to export the block, and then import it with + `metaflac --append anotherfile.flac < block` + +**\--remove-all** +: Remove all metadata blocks (except the STREAMINFO block) from the + metadata. Unless \--dont-use-padding is specified, the blocks will be + replaced with padding. + +**\--merge-padding** +: Merge adjacent PADDING blocks into single blocks. + +**\--sort-padding** +: Move all PADDING blocks to the end of the metadata and merge them + into a single block. + +# SEE ALSO + +**flac(1)** diff --git a/vendor/flac/microbench/CMakeLists.txt b/vendor/flac/microbench/CMakeLists.txt new file mode 100644 index 0000000..639915b --- /dev/null +++ b/vendor/flac/microbench/CMakeLists.txt @@ -0,0 +1,17 @@ +if(MSVC) + return() +endif() + +set(CMAKE_REQUIRED_LIBRARIES rt) +check_function_exists(clock_gettime HAVE_CLOCK_GETTIME) + +if(APPLE) + add_definitions(-DFLAC__SYS_DARWIN) +endif() + +add_executable(benchmark_residual benchmark_residual.c util.c) +target_include_directories(benchmark_residual PRIVATE + "$/include") +target_link_libraries(benchmark_residual + FLAC + $<$:rt>) diff --git a/vendor/flac/microbench/Makefile.am b/vendor/flac/microbench/Makefile.am new file mode 100644 index 0000000..81de3ad --- /dev/null +++ b/vendor/flac/microbench/Makefile.am @@ -0,0 +1,42 @@ +# FLAC - Free Lossless Audio Codec +# Copyright (C) 2015-2023 Xiph.Org Foundation +# +# Redistribution and use in source and binary forms, with or without +# modification, are permitted provided that the following conditions +# are met: +# +# - Redistributions of source code must retain the above copyright +# notice, this list of conditions and the following disclaimer. +# +# - Redistributions in binary form must reproduce the above copyright +# notice, this list of conditions and the following disclaimer in the +# documentation and/or other materials provided with the distribution. +# +# - Neither the name of the Xiph.org Foundation nor the names of its +# contributors may be used to endorse or promote products derived from +# this software without specific prior written permission. +# +# THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS +# ``AS IS'' AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT +# LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR +# A PARTICULAR PURPOSE ARE DISCLAIMED.

If you set `share__opterr' to + zero, the error message is suppressed but we still return '?'. + + If a char in OPTSTRING is followed by a colon, that means it wants an arg, + so the following text in the same ARGV-element, or the text of the following + ARGV-element, is returned in `share__optarg'. Two colons mean an option that + wants an optional arg; if there is text in the current ARGV-element, + it is returned in `share__optarg', otherwise `share__optarg' is set to zero. + + If OPTSTRING starts with `-' or `+', it requests different methods of + handling the non-option ARGV-elements. + See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above. + + Long-named options begin with `--' instead of `-'. + Their names may be abbreviated as long as the abbreviation is unique + or is an exact match for some defined option. If they have an + argument, it follows the option name in the same ARGV-element, separated + from the option name by a `=', or else the in next ARGV-element. + When `share__getopt' finds a long-named option, it returns 0 if that option's + `flag' field is nonzero, the value of the option's `val' field + if the `flag' field is zero. + + The elements of ARGV aren't really const, because we permute them. + But we pretend they're const in the prototype to be compatible + with other systems. + + LONGOPTS is a vector of `struct share__option' terminated by an + element containing a name which is zero. + + LONGIND returns the index in LONGOPT of the long-named option found. + It is only valid when a long-named option has been found by the most + recent call. + + If LONG_ONLY is nonzero, '-' as well as '--' can introduce + long-named options. */ + +int +share___getopt_internal ( + int argc, + char *const *argv, + const char *optstring, + const struct share__option *longopts, + int *longind, + int long_only ) +{ + share__optarg = NULL; + + if (share__optind == 0 || !share____getopt_initialized) + { + if (share__optind == 0) + share__optind = 1; /* Don't scan ARGV[0], the program name. */ + optstring = share___getopt_initialize (argc, argv, optstring); + share____getopt_initialized = 1; + } + + /* Test whether ARGV[share__optind] points to a non-option argument. + Either it does not have option syntax, or there is an environment flag + from the shell indicating it is not an option.

It is +based on the version found in the sourcecode of ttf.library 0.83b for +FreeType 1.3.1 from Richard Griffith (ragriffi@sprynet.com, +http://ragriffi.home.sprynet.com). + +You will also need the latest include files and amiga.lib from the +Amiga web site (https://os.amigaworld.de/download.php?id=3) for +AmigaOS 3.9; the generated code should work under AmigaOS 2.04 and up. + +To use it, call "smake assign" and then "smake" from the builds/amiga +directory. The results are: + +- A link library "ft2_680x0.lib" (where x depends on the setting of + the CPU entry in the smakefile) containing all FreeType2 parts + except of the init code, debugging code, and the system interface + code. + +- ftsystem.o, an object module containing the standard version of the + system interface code which uses fopen() fclose() fread() fseek() + ftell() malloc() realloc() and free() from lib:sc.lib (not pure). + +- ftsystempure.o, an object module containing the pure version of the + system interface code which uses Open() Close() Read() Seek() + ExamineFH() AsmAllocPooled() AsmFreePooled() etc. This version can + be used in both normal programs and in Amiga run-time shared system + librarys (can be linked with lib:libinit.o, no copying of DATA and + BSS hunks for each OpenLibrary() necessary). Source code is in + src/base/ftsystem.c. + +- ftdebug.o, an object module containing the standard version of the + debugging code which uses vprintf() and exit() (not pure). + Debugging can be turned on in FT:include/freetype/config/ftoption.h + and with FT_SetTraceLevel(). + +- ftdebugpure.o, an object module containing the pure version of the + debugging code which uses KVPrintf() from lib:debug.lib and no + exit(). For debugging of Amiga run-time shared system libraries. + Source code is in src/base/ftdebug.c. + +- NO ftinit.o. Because linking with a link library should result in + linking only the needed object modules in it, but standard + ftsystem.o would force ALL FreeType2 modules to be linked to your + program, I decided to use a different scheme: You must #include + FT:src/base/ftinit.c in your sourcecode and specify with #define + statements which modules you need. See + include/freetype/config/ftmodule.h. + + +To use in your own programs: + +- Insert the #define and #include statements from top of + include/freetype/config/ftmodule.h in your source code and + uncomment the #define statements for the FreeType2 modules you need. + +- You can use either PARAMETERS=REGISTER or PARAMETERS=STACK for + calling the FreeType2 functions, because the link library and the + object files are compiled with PARAMETERS=BOTH. + +- "smake assign" (assign "FT:" to the FreeType2 main directory). + +- Compile your program. + +- Link with either ftsystem.o or ftsystempure.o, if debugging enabled + with either ftdebug.o or (ftdebugpure.o and lib:debug.lib), and with + ft2_680x0.lib as link library. + + +To adapt to other compilers: + +- The standard ANSI C maximum length of 31 significant characters in + identifiers is not enough for FreeType2. Check if your compiler has + a minimum length of 40 significant characters or can be switched to + it. "idlen=40" is the option for SAS/C. Setting #define + HAVE_LIMIT_ON_IDENTS in an include file may also work (not tested). + +- Make sure that the include directory in builds/amiga is searched + before the normal FreeType2 include directory, so you are able to + replace problematic include files with your own version (same may be + useful for the src directory). + +- An example of how to replace/workaround a problematic include file + is include/freetype/config/ftconfig.h; it changes a #define that + would prevent SAS/C from generating XDEF's where it should do that and + then includes the standard FreeType2 include file. + +Local Variables: +coding: latin-1 +End: diff --git a/vendor/freetype/builds/amiga/include/config/ftconfig.h b/vendor/freetype/builds/amiga/include/config/ftconfig.h new file mode 100644 index 0000000..de074bf --- /dev/null +++ b/vendor/freetype/builds/amiga/include/config/ftconfig.h @@ -0,0 +1,55 @@ +/***************************************************************************/ +/* */ +/* ftconfig.h */ +/* */ +/* Amiga-specific configuration file (specification only). */ +/* */ +/* Copyright (C) 2005-2023 by */ +/* Werner Lemberg and Detlef Würkner. */ +/* */ +/* This file is part of the FreeType project, and may only be used, */ +/* modified, and distributed under the terms of the FreeType project */ +/* license, LICENSE.TXT.

What is this +--------------- + +Files in this directory are designed to build FreeType +running on classic MacOS. To build FreeType running on +Mac OS X, build as the system is UNIX. + +However, Mac OS X is most useful to manipulate files in +vanilla FreeType to fit classic MacOS. + +The information about MacOS specific API is written in +appendix of this document. + +2. Requirement +-------------- + +You can use MPW: a free-charged developer environment +by Apple, or CodeWarrior: a commercial developer +environment by Metrowerks. GCC for MPW and Symantec +"Think C" are not tested at present. + + + 2-1. Apple MPW + -------------- + + Following C compilers are tested: + + m68k target: Apple SC 8.9.0d3e1 + ppc target: Apple MrC 5.0.0d3c1 + + The final MPW-GM (official release on 1999/Dec) is too + old and cannot compile FreeType, because bundled C + compilers cannot search header files in sub directories. + Updating by the final MPW-PR (pre-release on 2001/Feb) + is required. + + Required files are downloadable from: + + http://macintoshgarden.org/apps/macintosh-programmers-workshop + + Also you can find documents how to update by MPW-PR. + + Python is required to restore MPW makefiles from the + skeletons. Python bundled to Mac OS X is enough. For + classic MacOS, MacPython is available: + + https://homepages.cwi.nl/~jack/macpython/ + + MPW requires all files are typed by resource fork. + ResEdit bundled to MPW is enough. In Mac OS X, + /Developer/Tools/SetFile of DevTool is useful to + manipulate from commandline. + + 2-2. Metrowerks CodeWarrior + --------------------------- + + XML project file is generated and tested by + CodeWarrior 9.0. Older versions are not tested + at all. At present, static library for ppc target + is available in the project file. + + +3. How to build +--------------- + + 3-1. Apple MPW + -------------- + Detailed building procedure by Apple MPW is + described in following. + + 3-1-1. Generate MPW makefiles from the skeletons + ------------------------------------------------ + + Here are 4 skeletons for following targets are + included. + + - FreeType.m68k_far.make.txt + Ancient 32bit binary executable format for + m68k MacOS: System 6, with 32bit addressing + mode (far-pointer-model) So-called "Toolbox" + API is used. + + - FreeType.m68k_cfm.make.txt + CFM binary executable format for m68k MacOS: + System 7. So-called "Toolbox" API is used. + + - FreeType.ppc_classic.make.txt + CFM binary executable format for ppc MacOS: + System 7, MacOS 8, MacOS 9. So-called "Toolbox" + API is used. + + - FreeType.ppc_carbon.make.txt + CFM binary executable format for ppc MacOS: + MacOS 9. Carbon API is used. + + At present, static library is only supported, + although targets except of m68k_far are capable + to use shared library. + + MPW makefile syntax uses 8bit characters. To keep + from violating them during version control, here + we store skeletons in pure ASCII format. You must + generate MPW makefile by Python script ascii2mpw.py. + + In Mac OS X terminal, you can convert as: + + python builds/mac/ascii2mpw.py \ + < builds/mac/FreeType.m68k_far.make.txt \ + > FreeType.m68k_far.make + + The skeletons are designed to use in the top + directory where there are builds, include, src etc. + You must name the generated MPW makefile by removing + ".txt" from source skeleton name. + + 3-1-2. Add resource forks to related files + ------------------------------------------ + + MPW's Make and C compilers cannot recognize files + without resource fork. You have to add resource + fork to the files that MPW uses. In Mac OS X + terminal of the system, you can do as: + + find . -name '*.[ch]' -exec \ + /Developer/Tools/SetFile -a l -c "MPS " -t TEXT \{\} \; + + find . -name '*.make' -exec \ + /Developer/Tools/SetFile -a l -c "MPS " -t TEXT \{\} \; + + + 3-1-3. Open MPW shell and build + ------------------------------- + + Open MPW shell and go to the top directory that + FreeType sources are extracted (MPW makefile must + be located in there), from "Set Directory" in + "Directory" menu. + + Choose "Build" from "Build" menu, and type the + name of project by removing ".make" from MPW + makefile, as: FreeType.m68k_far + + If building is successfully finished, you can find + built library in objs/ directory. + + + 3-2. Metrowerks CodeWarrior + --------------------------- + + Detailed building procedure by Metrowerks + CodeWarrior (CW) 9.0 is described in following. + + 3-2-1. Import XML project file + ------------------------------ + + CW XML project file is not ready for double- + click. Start CodeWarrior IDE, and choose + "Import project" in "File" menu. Choose XML + project file: builds/mac/ftlib.prj.xml. + In next, you will be asked where to save CW + native project file: you must choose + "builds/mac/ftlib.prj". The project file is + designed with relative path from there. After + CW native project file is generated, it is + automatically loaded, small project window + titled "ftlib.prj" is displayed. + + 3-2-2. Building + --------------- + Choose "Make" from "Project" menu. If building + is successfully finished, you can find built + library at objs/FreeTypeLib. + +4. TODO +------- + + 4-1. All modules should be included + ----------------------------------- + + At present, MPW makefiles and CW project file are + just updated versions of these by Leonard. Some + modules are added after the last maintenance, they + are not included. + + 4-2. Working test with ftdemos + ------------------------------ + + At present, MPW makefiles and CW project file can + build FreeType for classic MacOS. But their working + behaviours are not tested at all. Building ftdemos + for classic MacOS and working test is required. + + +APPENDIX I +---------- + + A-1. Framework dependencies + --------------------------- + + src/base/ftmac.c adds two Mac-specific features to + FreeType. These features are based on MacOS libraries. + + * accessing resource-fork font + The fonts for classic MacOS store their graphical data + in resource forks which cannot be accessed via ANSI C + functions. FreeType2 provides functions to handle such + resource fork fonts, they are based on File Manager + framework of MacOS. In addition, HFS and HFS+ file + system driver of Linux is supported. Following + functions are for this purpose. + + FT_New_Face_From_Resource() + FT_New_Face_From_FSSpec() + FT_New_Face_From_FSRef() + + * resolving font name to font file + The font menu of MacOS application prefers font name + written in FOND resource than sfnt resource. FreeType2 + provides functions to find font file by name in MacOS + application, they are based on QuickDraw Font Manager + and Apple Type Service framework of MacOS. + + FT_GetFile_From_Mac_Name() + FT_GetFile_From_Mac_ATS_Name() + + Working functions for each MacOS are summarized as + following. + + upto MacOS 6: + not tested (you have to obtain MPW 2.x) + + MacOS 7.x, 8.x, 9.x (without CarbonLib): + FT_GetFile_From_Mac_Name() + FT_New_Face_From_Resource() + FT_New_Face_From_FSSpec() + + MacOS 9.x (with CarbonLib): + FT_GetFile_From_Mac_Name() + FT_New_Face_From_Resource() + FT_New_Face_From_FSSpec() + FT_New_Face_From_FSRef() + + Mac OS X upto 10.4.x: + FT_GetFile_From_Mac_Name() deprecated + FT_New_Face_From_FSSpec() deprecated + FT_GetFile_From_Mac_ATS_Name() deprecated? + FT_New_Face_From_FSRef() + + A-2. Deprecated Functions + ------------------------- + + A-2-1. FileManager + ------------------ + + For convenience to write MacOS application, ftmac.c + provides functions to specify a file by FSSpec and FSRef, + because the file identification pathname had ever been + unrecommended method in MacOS programming. + + Toward to MacOS X 10.4 & 5, Carbon functions using FSSpec + datatype is noticed as deprecated, and recommended to + migrate to FSRef datatype. The big differences of FSRef + against FSSpec are explained in Apple TechNotes 2078. + + https://developer.apple.com/library/archive/technotes/tn2078/ + + - filename length: the max length of file + name of FSRef is 255 chars (it is limit of HFS+), + that of FSSpec is 31 chars (it is limit of HFS). + + - filename encoding: FSSpec is localized by + legacy encoding for each language system, + FSRef is Unicode enabled. + + A-2-2. FontManager + ------------------ + + Following functions receive QuickDraw fontname: + + FT_GetFile_From_Mac_Name() + + QuickDraw is deprecated and replaced by Quartz + since Mac OS X 10.4. They are still kept for + backward compatibility. By undefinition of + HAVE_QUICKDRAW in building, you can change these + functions to return FT_Err_Unimplemented always. + + Replacement functions are added for migration. + + FT_GetFile_From_Mac_ATS_Name() + + They are usable on Mac OS X only. On older systems, + these functions return FT_Err_Unimplemented always. + + The detailed incompatibilities and possibility + of FontManager emulation without QuickDraw is + explained in + + http://gyvern.ipc.hiroshima-u.ac.jp/~mpsuzuki/ats_benchmark.html + + A-3. Framework Availabilities + ----------------------------- + + The framework of MacOS are often revised, especially + when new format of binary executable is introduced. + Following table is the minimum version of frameworks + to use functions used in FreeType2.

To + support this I use the face_index argument of FT_(Open|New)_Face() + functions, and pretend the suitcase file is a collection. + + Warning: fbit and NFNT bitmap resources are not supported yet. In old + sfnt fonts, bitmap glyph data for each size is stored in each `NFNT' + resources instead of the `bdat' table in the sfnt resource. Therefore, + face->num_fixed_sizes is set to 0, because bitmap data in `NFNT' + resource is unavailable at present. + + The Mac FOND support works roughly like this: + + - Check whether the offered stream points to a Mac suitcase file. This + is done by checking the file type: it has to be 'FFIL' or 'tfil'. The + stream that gets passed to our init_face() routine is a stdio stream, + which isn't usable for us, since the FOND resources live in the + resource fork. So we just grab the stream->pathname field. + + - Read the FOND resource into memory, then check whether there is a + TrueType font and/or(!) a Type 1 font available. + + - If there is a Type 1 font available (as a separate `LWFN' file), read + its data into memory, massage it slightly so it becomes PFB data, wrap + it into a memory stream, load the Type 1 driver and delegate the rest + of the work to it by calling FT_Open_Face(). (XXX TODO: after this + has been done, the kerning data from the FOND resource should be + appended to the face: On the Mac there are usually no AFM files + available.

It +# sets the PTHREAD_LIBS output variable to the threads library and linker +# flags, and the PTHREAD_CFLAGS output variable to any special C compiler +# flags that are needed. (The user can also force certain compiler +# flags/libs to be tested by setting these environment variables.) +# +# Also sets PTHREAD_CC and PTHREAD_CXX to any special C compiler that is +# needed for multi-threaded programs (defaults to the value of CC +# respectively CXX otherwise). (This is necessary on e.g. AIX to use the +# special cc_r/CC_r compiler alias.) +# +# NOTE: You are assumed to not only compile your program with these flags, +# but also to link with them as well. For example, you might link with +# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS +# $PTHREAD_CXX $CXXFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS +# +# If you are only building threaded programs, you may wish to use these +# variables in your default LIBS, CFLAGS, and CC: +# +# LIBS="$PTHREAD_LIBS $LIBS" +# CFLAGS="$CFLAGS $PTHREAD_CFLAGS" +# CXXFLAGS="$CXXFLAGS $PTHREAD_CFLAGS" +# CC="$PTHREAD_CC" +# CXX="$PTHREAD_CXX" +# +# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant +# has a nonstandard name, this macro defines PTHREAD_CREATE_JOINABLE to +# that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX). +# +# Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the +# PTHREAD_PRIO_INHERIT symbol is defined when compiling with +# PTHREAD_CFLAGS. +# +# ACTION-IF-FOUND is a list of shell commands to run if a threads library +# is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it +# is not found. If ACTION-IF-FOUND is not specified, the default action +# will define HAVE_PTHREAD. +# +# Please let the authors know if this macro fails on any platform, or if +# you have any other suggestions or comments. This macro was based on work +# by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help +# from M. Frigo), as well as ac_pthread and hb_pthread macros posted by +# Alejandro Forero Cuervo to the autoconf macro repository.

    + FreeType 2 Project Files for VS.NET 2005 + (Pocket PC) +

    + +

    This directory contains project files for Visual C++, named +freetype.vcproj, and Visual Studio, called freetype.sln for +the following targets: + +

      +
    • PPC/SP 2003 (Pocket PC 2003)
      • +
    • PPC/SP WM5 (Windows Mobile 5)
      • +
    • PPC/SP WM6 (Windows Mobile 6)
      • +
    + +It compiles the following libraries from the FreeType 2.13.2 sources:

    + +
      + 
      +    freetype.lib     - release build; single threaded
+    freetype_D.lib   - debug build;   single threaded
+    freetypeMT.lib   - release build; multi-threaded
+    freetypeMT_D.lib - debug build;   multi-threaded
      +
    + +

    Be sure to extract the files with the Windows (CR+LF) line endings. ZIP +archives are already stored this way, so no further action is required. If +you use some .tar.*z archives, be sure to configure your extracting +tool to convert the line endings. For example, with WinZip, you should activate the TAR +file smart CR/LF Conversion option.

    + FreeType 2 Project Files for VS.NET 2008 + (Pocket PC) +

    + +

    This directory contains project files for Visual C++, named +freetype.dsp, and Visual Studio, called freetype.sln for +the following targets: + +

      +
    • PPC/SP 2003 (Pocket PC 2003)
      • +
    • PPC/SP WM5 (Windows Mobile 5)
      • +
    • PPC/SP WM6 (Windows Mobile 6)
      • +
    + +It compiles the following libraries from the FreeType 2.13.2 sources:

    + +
      + 
      +    freetype.lib     - release build; single threaded
+    freetype_D.lib   - debug build;   single threaded
+    freetypeMT.lib   - release build; multi-threaded
+    freetypeMT_D.lib - debug build;   multi-threaded
      +
    + +

    Be sure to extract the files with the Windows (CR+LF) line endings. ZIP +archives are already stored this way, so no further action is required. If +you use some .tar.*z archives, be sure to configure your extracting +tool to convert the line endings. For example, with WinZip, you should activate the TAR +file smart CR/LF Conversion option. Alternatively, you may consider +using the unix2dos or u2d utilities that are floating +around, which specifically deal with this particular problem. + +

    Build directories are placed in the top-level objs +directory.

    + FreeType 2 Project Files for Visual C++ 2010 or newer +

    + +

    This directory contains solution and project files for +Visual C++ 2010 or newer, named freetype.sln, +and freetype.vcxproj. It compiles the following libraries +from the FreeType 2.13.2 sources:

    + +
      +
    • freetype.dll using 'Release' or 'Debug' configurations
      • +
    • freetype.lib using 'Release Static' or 'Debug Static' configurations
      • +
    + +

    Both Win32 and x64 builds are supported. Build directories and target +files are placed in the top-level objs directory.

    + +

    Customization of the FreeType library is done by editing the +ftoption.h header file in the top-level devel path. +Alternatively, you may copy the file to another directory and change the +include directory in freetype.users.props.

    + +

    To configure library dependencies like zlib and libpng, +edit the freetype.users.props file in this directory. It also +simplifies automated (command-line) builds using msbuild.

    + +

    To link your executable with FreeType DLL, you may want to define +DLL_IMPORT so that the imported functions are appropriately +attributed with dllimport.

    + FreeType 2 Project Files for Visual C++ 6.0 and 2002-2008 +

    + +

    This directory contains project files freetype.dsp for +Visual C++ 6.0, and freetype.vcproj for Visual C++ 2002 +through 2008, which you might need to upgrade automatically. +It compiles the following libraries from the FreeType 2.13.2 sources:

    + +
      +
    • freetype.dll using 'Release' or 'Debug' configurations
      • +
    • freetype.lib using 'Release Static' or 'Debug Static' configurations
      • +
    + +

    Build directories and target files are placed in the top-level +objs directory.

    + +

    Be sure to extract the files with the Windows (CR+LF) line endings. ZIP +archives are already stored this way, so no further action is required. If +you use some .tar.*z archives, be sure to configure your extracting +tool to convert the line endings. For example, with WinZip, you should activate the TAR +file smart CR/LF Conversion option. Alternatively, you may consider +using the unix2dos or u2d utilities that are floating +around, which specifically deal with this particular problem. + +

    Build directories are placed in the top-level objs +directory.

    + FreeType 2 Project Files for Visual C++ and VS.NET 2005 + (Pocket PC) +

    + +

    This directory contains project files for Visual C++, named +freetype.dsp, and Visual Studio, called freetype.sln for +the following targets: + +

      +
    • PPC/SP 2003 (Pocket PC 2003)
      • +
    • PPC/SP WM5 (Windows Mobile 5)
      • +
    • PPC/SP WM6 (Windows Mobile 6)
      • +
    + +It compiles the following libraries from the FreeType 2.13.2 sources:

    + +
      + 
      +    freetype.lib     - release build; single threaded
+    freetype_D.lib   - debug build;   single threaded
+    freetypeMT.lib   - release build; multi-threaded
+    freetypeMT_D.lib - debug build;   multi-threaded
      +
    + +

    Be sure to extract the files with the Windows (CR+LF) line endings. ZIP +archives are already stored this way, so no further action is required. If +you use some .tar.*z archives, be sure to configure your extracting +tool to convert the line endings. For example, with WinZip, you should activate the TAR +file smart CR/LF Conversion option. Alternatively, you may consider +using the unix2dos or u2d utilities that are floating +around, which specifically deal with this particular problem. + +

    Build directories are placed in the top-level objs +directory.

See the @FT_Generic type + * description. + * + * bbox :: + * The font bounding box. Coordinates are expressed in font units (see + * `units_per_EM`). The box is large enough to contain any glyph from + * the font. Thus, `bbox.yMax` can be seen as the 'maximum ascender', + * and `bbox.yMin` as the 'minimum descender'.

This should be set for + * all common formats. + * + * FT_FACE_FLAG_VERTICAL :: + * The face contains vertical glyph metrics. This is only available in + * some formats, not all of them. + * + * FT_FACE_FLAG_KERNING :: + * The face contains kerning information. If set, the kerning distance + * can be retrieved using the function @FT_Get_Kerning. Otherwise the + * function always returns the vector (0,0). Note that FreeType + * doesn't handle kerning data from the SFNT 'GPOS' table (as present + * in many OpenType fonts). + * + * FT_FACE_FLAG_FAST_GLYPHS :: + * THIS FLAG IS DEPRECATED. DO NOT USE OR TEST IT. + * + * FT_FACE_FLAG_MULTIPLE_MASTERS :: + * The face contains multiple masters and is capable of interpolating + * between them. Supported formats are Adobe MM, TrueType GX, and + * OpenType variation fonts. + * + * See section @multiple_masters for API details. + * + * FT_FACE_FLAG_GLYPH_NAMES :: + * The face contains glyph names, which can be retrieved using + * @FT_Get_Glyph_Name. Note that some TrueType fonts contain broken + * glyph name tables. Use the function @FT_Has_PS_Glyph_Names when + * needed. + * + * FT_FACE_FLAG_EXTERNAL_STREAM :: + * Used internally by FreeType to indicate that a face's stream was + * provided by the client application and should not be destroyed when + * @FT_Done_Face is called. Don't read or test this flag. + * + * FT_FACE_FLAG_HINTER :: + * The font driver has a hinting machine of its own. For example, with + * TrueType fonts, it makes sense to use data from the SFNT 'gasp' + * table only if the native TrueType hinting engine (with the bytecode + * interpreter) is available and active. + * + * FT_FACE_FLAG_CID_KEYED :: + * The face is CID-keyed. In that case, the face is not accessed by + * glyph indices but by CID values. For subsetted CID-keyed fonts this + * has the consequence that not all index values are a valid argument + * to @FT_Load_Glyph. Only the CID values for which corresponding + * glyphs in the subsetted font exist make `FT_Load_Glyph` return + * successfully; in all other cases you get an + * `FT_Err_Invalid_Argument` error. + * + * Note that CID-keyed fonts that are in an SFNT wrapper (that is, all + * OpenType/CFF fonts) don't have this flag set since the glyphs are + * accessed in the normal way (using contiguous indices); the + * 'CID-ness' isn't visible to the application. + * + * FT_FACE_FLAG_TRICKY :: + * The face is 'tricky', that is, it always needs the font format's + * native hinting engine to get a reasonable result. A typical example + * is the old Chinese font `mingli.ttf` (but not `mingliu.ttc`) that + * uses TrueType bytecode instructions to move and scale all of its + * subglyphs. + * + * It is not possible to auto-hint such fonts using + * @FT_LOAD_FORCE_AUTOHINT; it will also ignore @FT_LOAD_NO_HINTING. + * You have to set both @FT_LOAD_NO_HINTING and @FT_LOAD_NO_AUTOHINT to + * really disable hinting; however, you probably never want this except + * for demonstration purposes. + * + * Currently, there are about a dozen TrueType fonts in the list of + * tricky fonts; they are hard-coded in file `ttobjs.c`. + * + * FT_FACE_FLAG_COLOR :: + * [Since 2.5.1] The face has color glyph tables.

Note that + * FreeType itself can't render SVG documents; however, the library + * provides hooks to seamlessly integrate an external renderer. See + * sections @ot_svg_driver and @svg_fonts for more. + * + * [Since 2.10, experimental] If the glyph index maps to an entry in + * the face's 'COLR' table with a 'CPAL' palette table (as defined in + * the OpenType specification), make @FT_Render_Glyph provide a default + * blending of the color glyph layers associated with the glyph index, + * using the same bitmap format as embedded color bitmap images.

Therefore, + * it requires the following. + * + * * @FTC_FaceID, an arbitrary non-zero value that uniquely identifies + * available or installed font faces, has to be provided to the + * cache by the client. Note that the cache only stores and compares + * these values and doesn't try to interpret them in any way, but they + * have to be persistent on the client side. + * + * * @FTC_Face_Requester, a method to convert an @FTC_FaceID into a new + * @FT_Face object when necessary, has to be provided to the cache by + * the client. The @FT_Face object is completely managed by the cache, + * including its termination through @FT_Done_Face. To monitor + * termination of face objects, the finalizer callback in the `generic` + * field of the @FT_Face object can be used, which might also be used + * to store the @FTC_FaceID of the face. + * + * Clients are free to map face IDs to anything useful. The most simple + * usage is, for example, to associate them to a `{pathname,face_index}` + * pair that is then used by @FTC_Face_Requester to call @FT_New_Face. + * However, more complex schemes are also possible. + * + * Note that for the cache to work correctly, the face ID values must be + * **persistent**, which means that the contents they point to should not + * change at runtime, or that their value should not become invalid. + * If this is unavoidable (e.g., when a font is uninstalled at runtime), + * you should call @FTC_Manager_RemoveFaceID as soon as possible to let + * the cache get rid of any references to the old @FTC_FaceID it may keep + * internally. Failure to do so will lead to incorrect behaviour or even + * crashes in @FTC_Face_Requester. + * + * To use the cache, start with calling @FTC_Manager_New to create a new + * @FTC_Manager object, which models a single cache instance. You can + * then look up @FT_Face and @FT_Size objects with + * @FTC_Manager_LookupFace and @FTC_Manager_LookupSize, respectively, and + * use them in any FreeType work stream. You can also cache other + * FreeType objects as follows. + * + * * If you want to use the charmap caching, call @FTC_CMapCache_New, + * then later use @FTC_CMapCache_Lookup to perform the equivalent of + * @FT_Get_Char_Index, only much faster. + * + * * If you want to use the @FT_Glyph caching, call @FTC_ImageCache_New, + * then later use @FTC_ImageCache_Lookup to retrieve the corresponding + * @FT_Glyph objects from the cache. + * + * * If you need lots of small bitmaps, it is much more memory-efficient + * to call @FTC_SBitCache_New followed by @FTC_SBitCache_Lookup.

Sometimes the + * vertical stems may be only partially black. In this context, + * 'anti-aliasing' means that stems are not positioned exactly on pixel + * borders, causing a fuzzy appearance. + * + * There are two principles behind this approach. + * + * 1) No hinting in the horizontal direction: Unlike 'superhinted' + * TrueType, which changes glyph widths to accommodate regular + * inter-glyph spacing, Adobe's approach is 'faithful to the design' in + * representing both the glyph width and the inter-glyph spacing designed + * for the font. This makes the screen display as close as it can be to + * the result one would get with infinite resolution, while preserving + * what is considered the key characteristics of each glyph. Note that + * the distances between unhinted and grid-fitted positions at small + * sizes are comparable to kerning values and thus would be noticeable + * (and distracting) while reading if hinting were applied. + * + * One of the reasons to not hint horizontally is anti-aliasing for LCD + * screens: The pixel geometry of modern displays supplies three vertical + * subpixels as the eye moves horizontally across each visible pixel. On + * devices where we can be certain this characteristic is present a + * rasterizer can take advantage of the subpixels to add increments of + * weight. In Western writing systems this turns out to be the more + * critical direction anyway; the weights and spacing of vertical stems + * (see above) are central to Armenian, Cyrillic, Greek, and Latin type + * designs. Even when the rasterizer uses greyscale anti-aliasing instead + * of color (a necessary compromise when one doesn't know the screen + * characteristics), the unhinted vertical features preserve the design's + * weight and spacing much better than aliased type would. + * + * 2) Alignment in the vertical direction: Weights and spacing along the + * y~axis are less critical; what is much more important is the visual + * alignment of related features (like cap-height and x-height). The + * sense of alignment for these is enhanced by the sharpness of grid-fit + * edges, while the cruder vertical resolution (full pixels instead of + * 1/3 pixels) is less of a problem. + * + * On the technical side, horizontal alignment zones for ascender, + * x-height, and other important height values (traditionally called + * 'blue zones') as defined in the font are positioned independently, + * each being rounded to the nearest pixel edge, taking care of overshoot + * suppression at small sizes, stem darkening, and scaling. + * + * Hstems (that is, hint values defined in the font to help align + * horizontal features) that fall within a blue zone are said to be + * 'captured' and are aligned to that zone. Uncaptured stems are moved + * in one of four ways, top edge up or down, bottom edge up or down. + * Unless there are conflicting hstems, the smallest movement is taken to + * minimize distortion. + * + */ + + + /************************************************************************** + * + * @section: + * pcf_driver + * + * @title: + * The PCF driver + * + * @abstract: + * Controlling the PCF driver module. + * + * @description: + * While FreeType's PCF driver doesn't expose API functions by itself, it + * is possible to control its behaviour with @FT_Property_Set and + * @FT_Property_Get.

Microsoft's GDI interface + * supported hinting of the right-side bearing point, such that the + * advance width could be non-linear. Most often this was done to + * achieve some level of glyph symmetry. To enable reasonable + * performance (e.g., not having to run hinting on all glyphs just to get + * the widths) there was a bit in the head table indicating if the side + * bearing was hinted, and additional tables, 'hdmx' and 'LTSH', to cache + * hinting widths across multiple sizes and device aspect ratios. + * + * _Font Smoothing_ + * + * Microsoft's GDI implementation of anti-aliasing. Not traditional + * anti-aliasing as the outlines were hinted before the sampling. The + * widths matched the bi-level rendering. + * + * _ClearType Rendering_ + * + * Technique that uses physical subpixels to improve rendering on LCD + * (and other) displays. Because of the higher resolution, many methods + * of improving symmetry in glyphs through hinting the right-side bearing + * were no longer necessary. This lead to what GDI calls 'natural + * widths' ClearType, see + * http://rastertragedy.com/RTRCh4.htm#Sec21. Since hinting + * has extra resolution, most non-linearity went away, but it is still + * possible for hints to change the advance widths in this mode. + * + * _ClearType Compatible Widths_ + * + * One of the earliest challenges with ClearType was allowing the + * implementation in GDI to be selected without requiring all UI and + * documents to reflow. To address this, a compatible method of + * rendering ClearType was added where the font hints are executed once + * to determine the width in bi-level rendering, and then re-run in + * ClearType, with the difference in widths being absorbed in the font + * hints for ClearType (mostly in the white space of hints); see + * http://rastertragedy.com/RTRCh4.htm#Sec20. Somewhat by + * definition, compatible width ClearType allows for non-linear widths, + * but only when the bi-level version has non-linear widths. + * + * _ClearType Subpixel Positioning_ + * + * One of the nice benefits of ClearType is the ability to more crisply + * display fractional widths; unfortunately, the GDI model of integer + * bitmaps did not support this. However, the WPF and Direct Write + * frameworks do support fractional widths. DWrite calls this 'natural + * mode', not to be confused with GDI's 'natural widths'. Subpixel + * positioning, in the current implementation of Direct Write, + * unfortunately does not support hinted advance widths, see + * http://rastertragedy.com/RTRCh4.htm#Sec22. Note that the + * TrueType interpreter fully allows the advance width to be adjusted in + * this mode, just the DWrite client will ignore those changes. + * + * _ClearType Backward Compatibility_ + * + * This is a set of exceptions made in the TrueType interpreter to + * minimize hinting techniques that were problematic with the extra + * resolution of ClearType; see + * http://rastertragedy.com/RTRCh4.htm#Sec1 and + * https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx. + * This technique is not to be confused with ClearType compatible widths. + * ClearType backward compatibility has no direct impact on changing + * advance widths, but there might be an indirect impact on disabling + * some deltas. This could be worked around in backward compatibility + * mode. + * + * _Native ClearType Mode_ + * + * (Not to be confused with 'natural widths'.) This mode removes all the + * exceptions in the TrueType interpreter when running with ClearType. + * Any issues on widths would still apply, though. + * + */ + + + /************************************************************************** + * + * @section: + * ot_svg_driver + * + * @title: + * The SVG driver + * + * @abstract: + * Controlling the external rendering of OT-SVG glyphs. + * + * @description: + * By default, FreeType can only load the 'SVG~' table of OpenType fonts + * if configuration macro `FT_CONFIG_OPTION_SVG` is defined.

It can also be used to generate error message strings + * with a small macro trick explained below. + * + * **Error Formats** + * + * The configuration macro `FT_CONFIG_OPTION_USE_MODULE_ERRORS` can be + * defined in `ftoption.h` in order to make the higher byte indicate the + * module where the error has happened (this is not compatible with + * standard builds of FreeType~2, however). See the file `ftmoderr.h` + * for more details. + * + * **Error Message Strings** + * + * Error definitions are set up with special macros that allow client + * applications to build a table of error message strings. The strings + * are not included in a normal build of FreeType~2 to save space (most + * client applications do not use them). + * + * To do so, you have to define the following macros before including + * this file. + * + * ``` + * FT_ERROR_START_LIST + * ``` + * + * This macro is called before anything else to define the start of the + * error list. It is followed by several `FT_ERROR_DEF` calls. + * + * ``` + * FT_ERROR_DEF( e, v, s ) + * ``` + * + * This macro is called to define one single error. 'e' is the error + * code identifier (e.g., `Invalid_Argument`), 'v' is the error's + * numerical value, and 's' is the corresponding error string. + * + * ``` + * FT_ERROR_END_LIST + * ``` + * + * This macro ends the list. + * + * Additionally, you have to undefine `FTERRORS_H_` before #including + * this file. + * + * Here is a simple example. + * + * ``` + * #undef FTERRORS_H_ + * #define FT_ERRORDEF( e, v, s ) { e, s }, + * #define FT_ERROR_START_LIST { + * #define FT_ERROR_END_LIST { 0, NULL } }; + * + * const struct + * { + * int err_code; + * const char* err_msg; + * } ft_errors[] = + * + * #include + * ``` + * + * An alternative to using an array is a switch statement. + * + * ``` + * #undef FTERRORS_H_ + * #define FT_ERROR_START_LIST switch ( error_code ) { + * #define FT_ERRORDEF( e, v, s ) case v: return s; + * #define FT_ERROR_END_LIST } + * ``` + * + * If you use `FT_CONFIG_OPTION_USE_MODULE_ERRORS`, `error_code` should + * be replaced with `FT_ERROR_BASE(error_code)` in the last example. + */ + + /* */ + + /* In previous FreeType versions we used `__FTERRORS_H__`.

These technologies are + * controlled differently and API described below, although always + * available, performs its function when appropriate method is enabled + * and does nothing otherwise. + * + * ClearType-style LCD rendering exploits the color-striped structure of + * LCD pixels, increasing the available resolution in the direction of + * the stripe (usually horizontal RGB) by a factor of~3. Using the + * subpixel coverages unfiltered can create severe color fringes + * especially when rendering thin features. Indeed, to produce + * black-on-white text, the nearby color subpixels must be dimmed + * evenly. Therefore, an equalizing 5-tap FIR filter should be applied + * to subpixel coverages regardless of pixel boundaries and should have + * these properties: + * + * 1. It should be symmetrical, like {~a, b, c, b, a~}, to avoid + * any shifts in appearance. + * + * 2. It should be color-balanced, meaning a~+ b~=~c, to reduce color + * fringes by distributing the computed coverage for one subpixel to + * all subpixels equally. + * + * 3. It should be normalized, meaning 2a~+ 2b~+ c~=~1.0 to maintain + * overall brightness. + * + * Boxy 3-tap filter {0, 1/3, 1/3, 1/3, 0} is sharper but is less + * forgiving of non-ideal gamma curves of a screen (and viewing angles), + * beveled filters are fuzzier but more tolerant. + * + * Use the @FT_Library_SetLcdFilter or @FT_Library_SetLcdFilterWeights + * API to specify a low-pass filter, which is then applied to + * subpixel-rendered bitmaps generated through @FT_Render_Glyph. + * + * Harmony LCD rendering is suitable to panels with any regular subpixel + * structure, not just monitors with 3 color striped subpixels, as long + * as the color subpixels have fixed positions relative to the pixel + * center. In this case, each color channel can be rendered separately + * after shifting the outline opposite to the subpixel shift so that the + * coverage maps are aligned. This method is immune to color fringes + * because the shifts do not change integral coverage. + * + * The subpixel geometry must be specified by xy-coordinates for each + * subpixel. By convention they may come in the RGB order: {{-1/3, 0}, + * {0, 0}, {1/3, 0}} for standard RGB striped panel or {{-1/6, 1/4}, + * {-1/6, -1/4}, {1/3, 0}} for a certain PenTile panel. + * + * Use the @FT_Library_SetLcdGeometry API to specify subpixel positions. + * If one follows the RGB order convention, the same order applies to the + * resulting @FT_PIXEL_MODE_LCD and @FT_PIXEL_MODE_LCD_V bitmaps. Note, + * however, that the coordinate frame for the latter must be rotated + * clockwise. Harmony with default LCD geometry is equivalent to + * ClearType with light filter. + * + * As a result of ClearType filtering or Harmony shifts, the resulting + * dimensions of LCD bitmaps can be slightly wider or taller than the + * dimensions the original outline with regard to the pixel grid. + * For example, for @FT_RENDER_MODE_LCD, the filter adds 2~subpixels to + * the left, and 2~subpixels to the right. The bitmap offset values are + * adjusted accordingly, so clients shouldn't need to modify their layout + * and glyph positioning code when enabling the filter. + * + * The ClearType and Harmony rendering is applicable to glyph bitmaps + * rendered through @FT_Render_Glyph, @FT_Load_Glyph, @FT_Load_Char, and + * @FT_Glyph_To_Bitmap, when @FT_RENDER_MODE_LCD or @FT_RENDER_MODE_LCD_V + * is specified. This API does not control @FT_Outline_Render and + * @FT_Outline_Get_Bitmap. + * + * The described algorithms can completely remove color artefacts when + * combined with gamma-corrected alpha blending in linear space. Each of + * the 3~alpha values (subpixels) must by independently used to blend one + * color channel.

By continuing to use, modify, or distribute +// this file you indicate that you have read the license and +// understand and accept it fully. + + +// This file contains data specific to blue zones. It gets processed by +// a script to simulate `jagged arrays', with enumeration values holding +// offsets into the arrays. +// +// The format of the file is rather simple: A section starts with three +// labels separated by whitespace and followed by a colon (everything in a +// single line); the first label gives the name of the enumeration template, +// the second the name of the array template, and the third the name of the +// `maximum' template. The script then fills the corresponding templates +// (indicated by `@' characters around the name). +// +// A section contains one or more data records. Each data record consists +// of two or more lines. The first line holds the enumeration name, and the +// remaining lines the corresponding array data. +// +// There are two possible representations for array data. +// +// - A string of characters or character clusters (for example, representing +// Aksharas, Devanagari syllables) in UTF-8 encoding enclosed in double +// quotes, using C syntax, where the elements are separated by spaces. +// There can be only one string per line, thus the starting and ending +// double quote must be the first and last character in the line, +// respectively, ignoring whitespace before and after the string. If +// there are multiple strings (in multiple lines), they are concatenated +// to a single string. In the output, a string gets represented as a +// series of singles bytes, followed by a zero byte. The enumeration +// values simply hold byte offsets to the start of the corresponding +// strings. +// +// For strings, the `maximum' template holds the maximum number of +// non-space characters in all strings. +// +// - Data blocks enclosed in balanced braces, which get copied verbatim and +// which can span multiple lines. The opening brace of a block must be +// the first character of a line (ignoring whitespace), and the closing +// brace the last (ignoring whitespace also). The script appends a comma +// character after each block and counts the number of blocks to set the +// enumeration values. +// +// For data blocks, the `maximum' template holds the maximum number of +// array elements. +// +// A section can contain either strings only or data blocks only. +// +// A comment line starts with `//'; it gets removed. A preprocessor +// directive line (using the standard syntax of `cpp') starts with `#' and +// gets copied verbatim to both the enumeration and the array. Whitespace +// outside of a string is insignificant. +// +// Preprocessor directives are ignored while the script computes maximum +// values; this essentially means that the maximum values can easily be too +// large. Given that the purpose of those values is to create local +// fixed-size arrays at compile time for further processing of the blue zone +// data, this isn't a problem. Note the final zero byte of a string is not +// counted. Note also that the count holds the number of UTF-8 encoded +// characters, not bytes. + + +// The blue zone string data, to be used in the blue stringsets below. + +AF_BLUE_STRING_ENUM AF_BLUE_STRINGS_ARRAY AF_BLUE_STRING_MAX_LEN: + + AF_BLUE_STRING_ADLAM_CAPITAL_TOP + "𞤌 𞤅 𞤈 𞤠𞤔 𞤚" + AF_BLUE_STRING_ADLAM_CAPITAL_BOTTOM + "𞤂 𞤖" + AF_BLUE_STRING_ADLAM_SMALL_TOP + "𞤬 𞤮 𞤻 𞤼 𞤾" + AF_BLUE_STRING_ADLAM_SMALL_BOTTOM + "𞤤 𞤨 𞤩 𞤭 𞤴 𞤸 𞤺 𞥀" + + AF_BLUE_STRING_ARABIC_TOP + "ا Ø¥ Ù„ Ùƒ Ø· ظ" + AF_BLUE_STRING_ARABIC_BOTTOM + "ت Ø« Ø· ظ Ùƒ" + // We don't necessarily have access to medial forms via Unicode in case + // Arabic presentational forms are missing.

+// +// A blue zone in general is defined by a reference and an overshoot line. +// During the hinting process, all coordinate values between those two lines +// are set equal to the reference value, provided that the blue zone is not +// wider than 0.75 pixels (otherwise the blue zone gets ignored). All +// entries must have `AF_BLUE_STRING_MAX' as the final line. +// +// During the glyph analysis, edges are sorted from bottom to top, and then +// sequentially checked, edge by edge, against the blue zones in the order +// given below. +// +// +// latin auto-hinter +// ----------------- +// +// Characters in a blue string are automatically classified as having a flat +// (reference) or a round (overshoot) extremum. The blue zone is then set +// up by the mean values of all flat extrema and all round extrema, +// respectively. Only horizontal blue zones (i.e., adjusting vertical +// coordinate values) are supported. +// +// Some scripts like Khmer need character composition to get all necessary +// blue zones, since Unicode only provides an abstract data model that +// doesn't represent all possible glyph shapes. For such character +// clusters, the HarfBuzz library is used to convert them into the +// corresponding glyphs. The largest glyph element (where `largest' can be +// either `largest ascender' or `largest descender') then defines the +// corresponding flat or round extremum. +// +// For the latin auto-hinter, the overshoot should be larger than the +// reference for top zones, and vice versa for bottom zones. +// +// LATIN_TOP +// Take the maximum flat and round coordinate values of the blue string +// characters for computing the blue zone's reference and overshoot +// values. +// +// If not set, take the minimum values. +// +// Mutually exclusive with `LATIN_SUB_TOP'. +// +// LATIN_SUB_TOP +// For all glyphs of a character cluster, compute the maximum flat +// and round coordinate values of each component, then take the +// smallest of the maximum values. The idea is to get the top of +// subscript glyphs, as used in Khmer, for example. Note that +// this mechanism doesn't work for ordinary ligatures. +// +// This flags indicates a secondary blue zone: It gets removed if +// there is a non-LATIN_SUB_TOP blue zone at the same coordinate +// value (after scaling). +// +// Mutually exclusive with `LATIN_TOP'. +// +// LATIN_NEUTRAL +// Ignore round extrema and define the blue zone with flat values only. +// Both top and bottom of contours can match. This is useful for +// scripts like Devanagari where vowel signs attach to the base +// character and are implemented as components of composite glyphs. +// +// If not set, both round and flat extrema are taken into account. +// Additionally, only the top or the bottom of a contour can match, +// depending on the LATIN_TOP flag. +// +// Neutral blue zones should always follow non-neutral blue zones. +// +// LATIN_X_HEIGHT +// Scale all glyphs vertically from the corresponding script to make the +// reference line of this blue zone align on the grid. The scaling +// takes place before all other blue zones get aligned to the grid. +// Only one blue character string of a script style can have this flag. +// +// LATIN_LONG +// Apply an additional constraint for blue zone values: Don't +// necessarily use the extremum as-is but a segment of the topmost (or +// bottommost) contour that is longer than a heuristic threshold, and +// which is not too far away vertically from the real extremum. This +// ensures that small bumps in the outline are ignored (for example, the +// `vertical serifs' found in many Hebrew glyph designs). +// +// The segment must be at least EM/25 font units long, and the distance +// to the extremum must be smaller than EM/4. +// +// +// cjk auto-hinter +// --------------- +// +// Characters in a blue string are *not* automatically classified. Instead, +// first come the characters used for the overshoot value, then the +// character `|', then the characters used for the reference value +// (everything separated by space characters). The blue zone is then set up +// by the mean values of all reference values and all overshoot values, +// respectively. Both horizontal and vertical blue zones (i.e., adjusting +// vertical and horizontal coordinate values, respectively) are supported. +// +// For the cjk auto-hinter, the overshoot should be smaller than the +// reference for top zones, and vice versa for bottom zones. +// +// CJK_TOP +// Take the maximum flat and round coordinate values of the blue string +// characters. If not set, take the minimum values. +// +// CJK_RIGHT +// A synonym for CJK_TOP. If CJK_HORIZ is set, this flag indicates the +// right blue zone, taking horizontal maximum values. +// +// CJK_HORIZ +// Define a blue zone for horizontal hinting (i.e., vertical blue +// zones).

An edge corresponds to a single position on the main + * dimension that collects one or more segments (allowing for a small + * threshold). + * + * As an example, the `latin' writing system first tries to grid-fit + * edges, then to align segments on the edges unless it detects that + * they form a serif. + * + * + * A H + * | | + * | | + * | | + * | | + * C | | F + * +------<-----+ +-----<------+ + * | B G | + * | | + * | | + * +--------------->------------------+ + * D E + * + * + * Stems + * + * Stems are detected by `af_{cjk,latin,...}_hint_edges'. + * + * Segments need to be `linked' to other ones in order to detect stems. + * A stem is made of two segments that face each other in opposite + * directions and that are sufficiently close to each other. Using + * vocabulary from the TrueType specification, stem segments form a + * `black distance'. + * + * In the above ASCII drawing, the horizontal segments are BC, DE, and + * FG; the vertical segments are AB, CD, EF, and GH. + * + * Each segment has at most one `best' candidate to form a black + * distance, or no candidate at all. Notice that two distinct segments + * can have the same candidate, which frequently means a serif. + * + * A stem is recognized by the following condition: + * + * best segment_1 = segment_2 && best segment_2 = segment_1 + * + * The best candidate is stored in field `link' in structure + * `AF_Segment'. + * + * In the above ASCII drawing, the best candidate for both AB and CD is + * GH, while the best candidate for GH is AB. Similarly, the best + * candidate for EF and GH is AB, while the best candidate for AB is + * GH. + * + * The detection and handling of stems is dependent on the writing + * system. + * + * + * Serifs + * + * Serifs are detected by `af_{cjk,latin,...}_hint_edges'. + * + * In comparison to a stem, a serif (as handled by the auto-hinter + * module that takes care of the `latin' writing system) has + * + * best segment_1 = segment_2 && best segment_2 != segment_1 + * + * where segment_1 corresponds to the serif segment (CD and EF in the + * above ASCII drawing). + * + * The best candidate is stored in field `serif' in structure + * `AF_Segment' (and `link' is set to NULL). + * + * + * Touched points + * + * A point is called `touched' if it has been processed somehow by the + * auto-hinter. It basically means that it shouldn't be moved again + * (or moved only under certain constraints to preserve the already + * applied processing). + * + * + * Flat and round segments + * + * Segments are `round' or `flat', depending on the series of points + * that define them. A segment is round if the next and previous point + * of an extremum (which can be either a single point or sequence of + * points) are both conic or cubic control points. Otherwise, a + * segment with an extremum is flat. + * + * + * Strong Points + * + * Experience has shown that points not part of an edge need to be + * interpolated linearly between their two closest edges, even if these + * are not part of the contour of those particular points. Typical + * candidates for this are + * + * - angle points (i.e., points where the `in' and `out' direction + * differ greatly) + * + * - inflection points (i.e., where the `in' and `out' angles are the + * same, but the curvature changes sign) [currently, such points + * aren't handled specially in the auto-hinter] + * + * `af_glyph_hints_align_strong_points' is the function that takes + * care of such situations; it is equivalent to the TrueType `IP' + * hinting instruction. + * + * + * Weak Points + * + * Other points in the outline must be interpolated using the + * coordinates of their previous and next unfitted contour neighbours. + * These are called `weak points' and are touched by the function + * `af_glyph_hints_align_weak_points', equivalent to the TrueType `IUP' + * hinting instruction.

To + support this I use the face_index argument of FT_(Open|New)_Face() + functions, and pretend the suitcase file is a collection. + + Warning: fbit and NFNT bitmap resources are not supported yet. In old + sfnt fonts, bitmap glyph data for each size is stored in each `NFNT' + resources instead of the `bdat' table in the sfnt resource. Therefore, + face->num_fixed_sizes is set to 0, because bitmap data in `NFNT' + resource is unavailable at present. + + The Mac FOND support works roughly like this: + + - Check whether the offered stream points to a Mac suitcase file. This + is done by checking the file type: it has to be 'FFIL' or 'tfil'. The + stream that gets passed to our init_face() routine is a stdio stream, + which isn't usable for us, since the FOND resources live in the + resource fork. So we just grab the stream->pathname field. + + - Read the FOND resource into memory, then check whether there is a + TrueType font and/or(!) a Type 1 font available. + + - If there is a Type 1 font available (as a separate `LWFN' file), read + its data into memory, massage it slightly so it becomes PFB data, wrap + it into a memory stream, load the Type 1 driver and delegate the rest + of the work to it by calling FT_Open_Face(). (XXX TODO: after this + has been done, the kerning data from the FOND resource should be + appended to the face: On the Mac there are usually no AFM files + available. However, this is tricky since we need to map Mac char + codes to ps glyph names to glyph ID's...) + + - If there is a TrueType font (an `sfnt' resource), read it into memory, + wrap it into a memory stream, load the TrueType driver and delegate + the rest of the work to it, by calling FT_Open_Face(). + + - Some suitcase fonts (notably Onyx) might point the `LWFN' file to + itself, even though it doesn't contains `POST' resources. To handle + this special case without opening the file an extra time, we just + ignore errors from the `LWFN' and fallback to the `sfnt' if both are + available. + */ + + +#include +#include +#include +#include +#include "ftbase.h" + + +#ifdef FT_MACINTOSH + + /* This is for Mac OS X.

The specification of the BDF font format is +available from Adobe's web site: + + https://adobe-type-tools.github.io/font-tech-notes/pdfs/5005.BDF_Spec.pdf + +Many good bitmap fonts in bdf format come with XFree86 (www.XFree86.org). +They do not define vertical metrics, because the X Consortium BDF +specification has removed them. + + +Encodings +********* + +[This section is out of date, retained for historical reasons. BDF + properties can be retrieved with `FT_Get_BDF_Property`, character set ID + values with `FT_Get_BDF_Charset_ID`.] + +The variety of encodings that accompanies bdf fonts appears to encompass the +small set defined in freetype.h. On the other hand, two properties that +specify encoding and registry are usually defined in bdf fonts. + +I decided to make these two properties directly accessible, leaving to the +client application the work of interpreting them. For instance: + + + #include FT_INTERNAL_BDF_TYPES_H + + FT_Face face; + BDF_Public_Face bdfface; + + + FT_New_Face( library, ..., &face ); + + bdfface = (BDF_Public_Face)face; + + if ( ( bdfface->charset_registry == "ISO10646" ) && + ( bdfface->charset_encoding == "1" ) ) + [..] + + +Thus the driver always exports `ft_encoding_none' as face->charmap.encoding. +FT_Get_Char_Index's behavior is unmodified, that is, it converts the ULong +value given as argument into the corresponding glyph number. + +If the two properties are not available, Adobe Standard Encoding should be +assumed. + + +Anti-Aliased Bitmaps +******************** + +The driver supports an extension to the BDF format as used in Mark Leisher's +xmbdfed bitmap font editor. Microsoft's SBIT tool expects bitmap fonts in +that format for adding anti-aliased them to TrueType fonts. It introduces a +fourth field to the `SIZE' keyword which gives the bpp value (bits per +pixel) of the glyph data in the font. Possible values are 1 (the default), +2 (four gray levels), 4 (16 gray levels), and 8 (256 gray levels). The +driver returns either a bitmap with 1 bit per pixel or a pixmap with 8bits +per pixel (using 4, 16, and 256 gray levels, respectively). + + +Known problems +************** + +- A font is entirely loaded into memory. Obviously, this is not the Right + Thing(TM). If you have big fonts I suggest you convert them into PCF + format (using the bdftopcf utility): the PCF font drive of FreeType can + perform incremental glyph loading. + +When I have some time, I will implement on-demand glyph parsing. + +- Except for encodings properties, client applications have no visibility of + the PCF_Face object. This means that applications cannot directly access + font tables and must trust FreeType. + +- Currently, glyph names are ignored. + + I plan to give full visibility of the BDF_Face object in an upcoming + revision of the driver, thus implementing also glyph names. + +- As I have never seen a BDF font that defines vertical metrics, vertical + metrics are (parsed and) discarded. If you own a BDF font that defines + vertical metrics, please let me know (I will implement them in 5-10 + minutes). + + +License +******* + +Copyright (C) 2001-2002 by Francesco Zappa Nardelli + +Permission is hereby granted, free of charge, to any person obtaining +a copy of this software and associated documentation files (the +"Software"), to deal in the Software without restriction, including +without limitation the rights to use, copy, modify, merge, publish, +distribute, sublicense, and/or sell copies of the Software, and to +permit persons to whom the Software is furnished to do so, subject to +the following conditions: + +The above copyright notice and this permission notice shall be +included in all copies or substantial portions of the Software. + +THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, +EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF +MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. +IN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY +CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, +TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE +SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE. + +*** Portions of the driver (that is, bdflib.c and bdf.h): + +Copyright 2000 Computing Research Labs, New Mexico State University +Copyright 2001-2002, 2011 Francesco Zappa Nardelli + +Permission is hereby granted, free of charge, to any person obtaining a +copy of this software and associated documentation files (the "Software"), +to deal in the Software without restriction, including without limitation +the rights to use, copy, modify, merge, publish, distribute, sublicense, +and/or sell copies of the Software, and to permit persons to whom the +Software is furnished to do so, subject to the following conditions: + +The above copyright notice and this permission notice shall be included in +all copies or substantial portions of the Software. + +THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR +IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, +FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

What is this +--------------- + + `gxvalid' is a module to validate TrueType GX tables: a collection of + additional tables in TrueType font which are used by `QuickDraw GX + Text', Apple Advanced Typography (AAT). In addition, gxvalid can + validates `kern' tables which have been extended for AAT. Like the + otvalid module, gxvalid uses FreeType 2's validator framework + (ftvalid). + + You can link gxvalid with your program; before running your own layout + engine, gxvalid validates a font file. As the result, you can remove + error-checking code from the layout engine. It is also possible to + use gxvalid as a stand-alone font validator; the `ftvalid' test + program included in the ft2demo bundle calls gxvalid internally. + A stand-alone font validator may be useful for font developers. + + This documents documents the following issues. + + - supported TrueType GX tables + - fundamental validation limitations + - permissive error handling of broken GX tables + - `kern' table issue. + + +2. Supported tables +------------------- + + The following GX tables are currently supported. + + bsln + feat + just + kern(*) + lcar + mort + morx + opbd + prop + trak + + The following GX tables are currently unsupported. + + cvar + fdsc + fmtx + fvar + gvar + Zapf + + The following GX tables won't be supported. + + acnt(**) + hsty(***) + + The following undocumented tables in TrueType fonts designed for Apple + platform aren't handled either. + + addg + CVTM + TPNM + umif + + + *) The `kern' validator handles both the classic and the new kern + formats; the former is supported on both Microsoft and Apple + platforms, while the latter is supported on Apple platforms. + + **) `acnt' tables are not supported by currently available Apple font + tools. + + ***) There is one more Apple extension, `hsty', but it is for + Newton-OS, not GX (Newton-OS is a platform by Apple, but it can + use sfnt- housed bitmap fonts only). Therefore, it should be + excluded from `Apple platform' in the context of TrueType. + gxvalid ignores it as Apple font tools do so. + + + We have checked 183 fonts bundled with MacOS 9.1, MacOS 9.2, MacOS + 10.0, MacOS X 10.1, MSIE for MacOS, and AppleWorks 6.0. In addition, + we have checked 67 Dynalab fonts (designed for MacOS) and 189 Ricoh + fonts (designed for Windows and MacOS dual platforms). The number of + fonts including TrueType GX tables are as follows. + + bsln: 76 + feat: 191 + just: 84 + kern: 59 + lcar: 4 + mort: 326 + morx: 19 + opbd: 4 + prop: 114 + trak: 16 + + Dynalab and Ricoh fonts don't have GX tables except of `feat' and + `mort'. + + +3. Fundamental validation limitations +------------------------------------- + + TrueType GX provides layout information to libraries for font + rasterizers and text layout. gxvalid can check whether the layout + data in a font is conformant to the TrueType GX format specified by + Apple. But gxvalid cannot check a how QuickDraw GX/AAT renderer uses + the stored information. + + 3-1. Validation of State Machine activity + ----------------------------------------- + + QuickDraw GX/AAT uses a `State Machine' to provide `stateful' layout + features, and TrueType GX stores the state transition diagram of + this `State Machine' in a `StateTable' data structure. While the + State Machine receives a series of glyph IDs, the State Machine + starts with `start of text' state, walks around various states and + generates various layout information to the renderer, and finally + reaches the `end of text' state. + + gxvalid can check essential errors like: + + - possibility of state transitions to undefined states + - existence of glyph IDs that the State Machine doesn't know how + to handle + - the State Machine cannot compute the layout information from + given diagram + + These errors can be checked within finite steps, and without the + State Machine itself, because these are `expression' errors of state + transition diagram. + + There is no limitation about how long the State Machine walks + around, so validation of the algorithm in the state transition + diagram requires infinite steps, even if we had a State Machine in + gxvalid. Therefore, the following errors and problems cannot be + checked. + + - existence of states which the State Machine never transits to + - the possibility that the State Machine never reaches `end of + text' + - the possibility of stack underflow/overflow in the State Machine + (in ligature and contextual glyph substitutions, the State + Machine can store 16 glyphs onto its stack) + + In addition, gxvalid doesn't check `temporary glyph IDs' used in the + chained State Machines (in `mort' and `morx' tables). If a layout + feature is implemented by a single State Machine, a glyph ID + converted by the State Machine is passed to the glyph renderer, thus + it should not point to an undefined glyph ID. But if a layout + feature is implemented by chained State Machines, a component State + Machine (if it is not the final one) is permitted to generate + undefined glyph IDs for temporary use, because it is handled by next + component State Machine and not by the glyph renderer. To validate + such temporary glyph IDs, gxvalid must stack all undefined glyph IDs + which can occur in the output of the previous State Machine and + search them in the `ClassTable' structure of the current State + Machine. It is too complex to list all possible glyph IDs from the + StateTable, especially from a ligature substitution table. + + 3-2. Validation of relationship between multiple layout features + ---------------------------------------------------------------- + + gxvalid does not validate the relationship between multiple layout + features at all. + + If multiple layout features are defined in TrueType GX tables, + possible interactions, overrides, and conflicts between layout + features are implicitly given in the font too. For example, there + are several predefined spacing control features: + + - Text Spacing (Proportional/Monospace/Half-width/Normal) + - Number Spacing (Monospaced-numbers/Proportional-numbers) + - Kana Spacing (Full-width/Proportional) + - Ideographic Spacing (Full-width/Proportional) + - CJK Roman Spacing (Half-width/Proportional/Default-roman + /Full-width-roman/Proportional) + + If all layout features are independently managed, we can activate + inconsistent typographic rules like `Text Spacing=Monospace' and + `Ideographic Spacing=Proportional' at the same time. + + The combinations of layout features is managed by a 32bit integer + (one bit each for selector setting), so we can define relationships + between up to 32 features, theoretically. But if one feature + setting affects another feature setting, we need typographic + priority rules to validate the relationship. Unfortunately, the + TrueType GX format specification does not give such information even + for predefined features. + + +4. Permissive error handling of broken GX tables +------------------------------------------------ + + When Apple's font rendering system finds an inconsistency, like a + specification violation or an unspecified value in a TrueType GX + table, it does not always return error. In most cases, the rendering + engine silently ignores such wrong values or even whole tables. In + fact, MacOS is shipped with fonts including broken GX/AAT tables, but + no harmful effects due to `officially broken' fonts are observed by + end-users. + + gxvalid is designed to continue the validation process as long as + possible. When gxvalid find wrong values, gxvalid warns it at least, + and takes a fallback procedure if possible. The fallback procedure + depends on the debug level. + + We used the following three tools to investigate Apple's error handling. + + - FontValidator (for MacOS 8.5 - 9.2) resource fork font + - ftxvalidator (for MacOS X 10.1 -) dfont or naked-sfnt + - ftxdumperfuser (for MacOS X 10.1 -) dfont or naked-sfnt + + However, all tests were done on a PowerPC based Macintosh; at present, + we have not checked those tools on a m68k-based Macintosh. + + In total, we checked 183 fonts bundled to MacOS 9.1, MacOS 9.2, MacOS + 10.0, MacOS X 10.1, MSIE for MacOS, and AppleWorks 6.0. These fonts + are distributed officially, but many broken GX/AAT tables were found + by Apple's font tools. In the following, we list typical violation of + the GX specification, in fonts officially distributed with those Apple + systems. + + 4-1. broken BinSrchHeader (19/183) + ---------------------------------- + + `BinSrchHeader' is a header of a data array for m68k platforms to + access memory efficiently. Although there are only two independent + parameters for real (`unitSize' and `nUnits'), BinSrchHeader has + three additional parameters which can be calculated from `unitSize' + and `nUnits', for fast setup. Apple font tools ignore them + silently, so gxvalid warns if it finds and inconsistency, and always + continues validation. The additional parameters are ignored + regardless of the consistency. + + 19 fonts include such inconsistencies; all breaks are in the + BinSrchHeader structure of the `kern' table. + + 4-2. too-short LookupTable (5/183) + ---------------------------------- + + LookupTable format 0 is a simple array to get a value from a given + GID (glyph ID); the index of this array is a GID too. Therefore, + the length of the array is expected to be same as the maximum GID + value defined in the `maxp' table, but there are some fonts whose + LookupTable format 0 is too short to cover all GIDs. FontValidator + ignores this error silently, ftxvalidator and ftxdumperfuser both + warn and continue. Similar problems are found in format 3 subtables + of `kern'. gxvalid warns always and abort if the validation level + is set to FT_VALIDATE_PARANOID. + + 5 fonts include too-short kern format 0 subtables. + 1 font includes too-short kern format 3 subtable. + + 4-3. broken LookupTable format 2 (1/183) + ---------------------------------------- + + LookupTable format 2, subformat 4 covers the GID space by a + collection of segments which are specified by `firstGlyph' and + `lastGlyph'. Some fonts store `firstGlyph' and `lastGlyph' in + reverse order, so the segment specification is broken. Apple font + tools ignore this error silently; a broken segment is ignored as if + it did not exist. gxvalid warns and normalize the segment at + FT_VALIDATE_DEFAULT, or ignore the segment at FT_VALIDATE_TIGHT, or + abort at FT_VALIDATE_PARANOID. + + 1 font includes broken LookupTable format 2, in the `just' table. + + *) It seems that all fonts manufactured by ITC for AppleWorks have + this error. + + 4-4. bad bracketing in glyph property (14/183) + ---------------------------------------------- + + GX/AAT defines a `bracketing' property of the glyphs in the `prop' + table, to control layout features of strings enclosed inside and + outside of brackets. Some fonts give inappropriate bracket + properties to glyphs. Apple font tools warn about this error; + gxvalid warns too and aborts at FT_VALIDATE_PARANOID. + + 14 fonts include wrong bracket properties. + + + 4-5. invalid feature number (117/183) + ------------------------------------- + + The GX/AAT extension can include 255 different layout features, + but popular layout features are predefined (see + https://developer.apple.com/fonts/TrueType-Reference-Manual/RM09/AppendixF.html). + Some fonts include feature numbers which are incompatible with the + predefined feature registry. + + In our survey, there are 140 fonts including `feat' table. + + a) 67 fonts use a feature number which should not be used. + b) 117 fonts set the wrong feature range (nSetting). This is mostly + found in the `mort' and `morx' tables. + + Apple font tools give no warning, although they cannot recognize + what the feature is. At FT_VALIDATE_DEFAULT, gxvalid warns but + continues in both cases (a, b). At FT_VALIDATE_TIGHT, gxvalid warns + and aborts for (a), but continues for (b). At FT_VALIDATE_PARANOID, + gxvalid warns and aborts in both cases (a, b). + + 4-6. invalid prop version (10/183) + ---------------------------------- + + As most TrueType GX tables, the `prop' table must start with a 32bit + version identifier: 0x00010000, 0x00020000 or 0x00030000. But some + fonts store nonsense binary data instead. When Apple font tools + find them, they abort the processing immediately, and the data which + follows is unhandled. gxvalid does the same. + + 10 fonts include broken `prop' version. + + All of these fonts are classic TrueType fonts for the Japanese + script, manufactured by Apple. + + 4-7. unknown resource name (2/183) + ------------------------------------ + + NOTE: THIS IS NOT A TRUETYPE GX ERROR. + + If a TrueType font is stored in the resource fork or in dfont + format, the data must be tagged as `sfnt' in the resource fork index + to invoke TrueType font handler for the data. But the TrueType font + data in `Keyboard.dfont' is tagged as `kbd', and that in + `LastResort.dfont' is tagged as `lst'. Apple font tools can detect + that the data is in TrueType format and successfully validate them. + Maybe this is possible because they are known to be dfont. The + current implementation of the resource fork driver of FreeType + cannot do that, thus gxvalid cannot validate them. + + 2 fonts use an unknown tag for the TrueType font resource. + +5. `kern' table issues +---------------------- + + In common terminology of TrueType, `kern' is classified as a basic and + platform-independent table. But there are Apple extensions of `kern', + and there is an extension which requires a GX state machine for + contextual kerning. Therefore, gxvalid includes a special validator + for `kern' tables. Unfortunately, there is no exact algorithm to + check Apple's extension, so gxvalid includes a heuristic algorithm to + find the proper validation routines for all possible data formats, + including the data format for Microsoft. By calling + classic_kern_validate() instead of gxv_validate(), you can specify the + `kern' format explicitly. However, current FreeType2 uses Microsoft + `kern' format only, others are ignored (and should be handled in a + library one level higher than FreeType). + + 5-1. History + ------------ + + The original 16bit version of `kern' was designed by Apple in the + pre-GX era, and it was also approved by Microsoft. Afterwards, + Apple designed a new 32bit version of the `kern' table. According + to the documentation, the difference between the 16bit and 32bit + version is only the size of variables in the `kern' header. In the + following, we call the original 16bit version as `classic', and + 32bit version as `new'. + + 5-2. Versions and dialects which should be differentiated + --------------------------------------------------------- + + The `kern' table consists of a table header and several subtables. + The version number which identifies a `classic' or a `new' version + is explicitly written in the table header, but there are + undocumented differences between Microsoft's and Apple's formats. + It is called a `dialect' in the following. There are three cases + which should be handled: the new Apple-dialect, the classic + Apple-dialect, and the classic Microsoft-dialect. An analysis of + the formats and the auto detection algorithm of gxvalid is described + in the following. + + 5-2-1. Version detection: classic and new kern + ---------------------------------------------- + + According to Apple TrueType specification, there are only two + differences between the classic and the new: + + - The `kern' table header starts with the version number. + The classic version starts with 0x0000 (16bit), + the new version starts with 0x00010000 (32bit). + + - In the `kern' table header, the number of subtables follows + the version number. + In the classic version, it is stored as a 16bit value. + In the new version, it is stored as a 32bit value. + + From Apple font tool's output (DumpKERN is also tested in addition + to the three Apple font tools in above), there is another + undocumented difference. In the new version, the subtable header + includes a 16bit variable named `tupleIndex' which does not exist + in the classic version. + + The new version can store all subtable formats (0, 1, 2, and 3), + but the Apple TrueType specification does not mention the subtable + formats available in the classic version. + + 5-2-2. Available subtable formats in classic version + ---------------------------------------------------- + + Although the Apple TrueType specification recommends to use the + classic version in the case if the font is designed for both the + Apple and Microsoft platforms, it does not document the available + subtable formats in the classic version. + + According to the Microsoft TrueType specification, the subtable + format assured for Windows and OS/2 support is only subtable + format 0. The Microsoft TrueType specification also describes + subtable format 2, but does not mention which platforms support + it. Subtable formats 1, 3, and higher are documented as reserved + for future use. Therefore, the classic version can store subtable + formats 0 and 2, at least. `ttfdump.exe', a font tool provided by + Microsoft, ignores the subtable format written in the subtable + header, and parses the table as if all subtables are in format 0. + + `kern' subtable format 1 uses a StateTable, so it cannot be + utilized without a GX State Machine. Therefore, it is reasonable + to assume that format 1 (and 3) were introduced after Apple had + introduced GX and moved to the new 32bit version. + + 5-2-3. Apple and Microsoft dialects + ----------------------------------- + + The `kern' subtable has a 16bit `coverage' field to describe + kerning attributes, but bit interpretations by Apple and Microsoft + are different: For example, Apple uses bits 0-7 to identify the + subtable, while Microsoft uses bits 8-15. + + In addition, due to the output of DumpKERN and FontValidator, + Apple's bit interpretations of coverage in classic and new version + are incompatible also. In summary, there are three dialects: + classic Apple dialect, classic Microsoft dialect, and new Apple + dialect. The classic Microsoft dialect and the new Apple dialect + are documented by each vendors' TrueType font specification, but + the documentation for classic Apple dialect is not available. + + For example, in the new Apple dialect, bit 15 is documented as + `set to 1 if the kerning is vertical'. On the other hand, in + classic Microsoft dialect, bit 1 is documented as `set to 1 if the + kerning is horizontal'. From the outputs of DumpKERN and + FontValidator, classic Apple dialect recognizes 15 as `set to 1 + when the kerning is horizontal'. From the results of similar + experiments, classic Apple dialect seems to be the Endian reverse + of the classic Microsoft dialect. + + As a conclusion it must be noted that no font tool can identify + classic Apple dialect or classic Microsoft dialect automatically. + + 5-2-4. gxvalid auto dialect detection algorithm + ----------------------------------------------- + + The first 16 bits of the `kern' table are enough to identify the + version: + + - if the first 16 bits are 0x0000, the `kern' table is in + classic Apple dialect or classic Microsoft dialect + - if the first 16 bits are 0x0001, and next 16 bits are 0x0000, + the kern table is in new Apple dialect. + + If the `kern' table is a classic one, the 16bit `coverage' field + is checked next. Firstly, the coverage bits are decoded for the + classic Apple dialect using the following bit masks (this is based + on DumpKERN output): + + 0x8000: 1=horizontal, 0=vertical + 0x4000: not used + 0x2000: 1=cross-stream, 0=normal + 0x1FF0: reserved + 0x000F: subtable format + + If any of reserved bits are set or the subtable bits is + interpreted as format 1 or 3, we take it as `impossible in classic + Apple dialect' and retry, using the classic Microsoft dialect. + + The most popular coverage in new Apple-dialect: 0x8000, + The most popular coverage in classic Apple-dialect: 0x0000, + The most popular coverage in classic Microsoft dialect: 0x0001. + + 5-3. Tested fonts + ----------------- + + We checked 59 fonts bundled with MacOS and 38 fonts bundled with + Windows, where all font include a `kern' table. + + - fonts bundled with MacOS + * new Apple dialect + format 0: 18 + format 2: 1 + format 3: 1 + * classic Apple dialect + format 0: 14 + * classic Microsoft dialect + format 0: 15 + + - fonts bundled with Windows + * classic Microsoft dialect + format 0: 38 + + It looks strange that classic Microsoft-dialect fonts are bundled to + MacOS: they come from MSIE for MacOS, except of MarkerFelt.dfont. + + + ACKNOWLEDGEMENT + --------------- + + Some parts of gxvalid are derived from both the `gxlayout' module and + the `otvalid' module. Development of gxlayout was supported by the + Information-technology Promotion Agency(IPA), Japan. + + The detailed analysis of undefined glyph ID utilization in `mort' and + `morx' tables is provided by George Williams. + +------------------------------------------------------------------------ + +Copyright (C) 2004-2023 by +suzuki toshiya, Masatake YAMATO, Red hat K.K., +David Turner, Robert Wilhelm, and Werner Lemberg. + +This file is part of the FreeType project, and may only be used, +modified, and distributed under the terms of the FreeType project +license, LICENSE.TXT.

The NEEDBITS() macro is usually the way the state evaluates + whether it can proceed or should return. NEEDBITS() does the return if + the requested bits are not available. The typical use of the BITS macros + is: + + NEEDBITS(n); + ... do something with BITS(n) ... + DROPBITS(n); + + where NEEDBITS(n) either returns from inflate() if there isn't enough + input left to load n bits into the accumulator, or it continues. BITS(n) + gives the low n bits in the accumulator. When done, DROPBITS(n) drops + the low n bits off the accumulator. INITBITS() clears the accumulator + and sets the number of available bits to zero. BYTEBITS() discards just + enough bits to put the accumulator on a byte boundary. After BYTEBITS() + and a NEEDBITS(8), then BITS(8) would return the next byte in the stream. + + NEEDBITS(n) uses PULLBYTE() to get an available byte of input, or to return + if there is no input available. The decoding of variable length codes uses + PULLBYTE() directly in order to pull just enough bytes to decode the next + code, and no more. + + Some states loop until they get enough input, making sure that enough + state information is maintained to continue the loop where it left off + if NEEDBITS() returns in the loop. For example, want, need, and keep + would all have to actually be part of the saved state in case NEEDBITS() + returns: + + case STATEw: + while (want < need) { + NEEDBITS(n); + keep[want++] = BITS(n); + DROPBITS(n); + } + state = STATEx; + case STATEx: + + As shown above, if the next state is also the next case, then the break + is omitted. + + A state may also return if there is not enough output space available to + complete that state. Those states are copying stored data, writing a + literal byte, and copying a matching string. + + When returning, a "goto inf_leave" is used to update the total counters, + update the check value, and determine whether any progress has been made + during that inflate() call in order to return the proper return code. + Progress is defined as a change in either strm->avail_in or strm->avail_out. + When there is a window, goto inf_leave will update the window with the last + output written. If a goto inf_leave occurs in the middle of decompression + and there is no window currently, goto inf_leave will create one and copy + output to the window for the next call of inflate(). + + In this implementation, the flush parameter of inflate() only affects the + return code (per zlib.h). inflate() always writes as much as possible to + strm->next_out, given the space available and the provided input--the effect + documented in zlib.h of Z_SYNC_FLUSH. Furthermore, inflate() always defers + the allocation of and copying into a sliding window until necessary, which + provides the effect documented in zlib.h for Z_FINISH when the entire input + stream available.

This allows the caller to determine the length of the + deflate block header for later use in random access within a deflate block. + 256 is added to the value of strm->data_type when inflate() returns + immediately after reaching the end of the deflate block header. + + inflate() should normally be called until it returns Z_STREAM_END or an + error.

Z_FINISH also informs inflate to not maintain a sliding window if the + stream completes, which reduces inflate's memory footprint. If the stream + does not complete, either because not all of the stream is provided or not + enough output space is provided, then a sliding window will be allocated and + inflate() can be called again to continue the operation as if Z_NO_FLUSH had + been used. + + In this implementation, inflate() always flushes as much output as + possible to the output buffer, and always uses the faster approach on the + first call. So the effects of the flush parameter in this implementation are + on the return value of inflate() as noted below, when inflate() returns early + when Z_BLOCK or Z_TREES is used, and when inflate() avoids the allocation of + memory for a sliding window when Z_FINISH is used. + + If a preset dictionary is needed after this call (see inflateSetDictionary + below), inflate sets strm->adler to the Adler-32 checksum of the dictionary + chosen by the compressor and returns Z_NEED_DICT; otherwise it sets + strm->adler to the Adler-32 checksum of all output produced so far (that is, + total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described + below. At the end of the stream, inflate() checks that its computed Adler-32 + checksum is equal to that saved by the compressor and returns Z_STREAM_END + only if the checksum is correct. + + inflate() can decompress and check either zlib-wrapped or gzip-wrapped + deflate data.

This code implements a PCF driver for the FreeType library. +Glyph images are loaded into memory only on demand, thus leading to a small +memory footprint. + +Information on the PCF font format can only be worked out from +`pcfread.c', and `pcfwrite.c', to be found, for instance, in the XFree86 +(www.xfree86.org) source tree (xc/lib/font/bitmap/). + +Many good bitmap fonts in bdf format come with XFree86: they can be +compiled into the pcf format using the `bdftopcf' utility. + + +Supported hardware +****************** + +The driver has been tested on linux/x86 and sunos5.5/sparc. In both +cases the compiler was gcc. When back in Paris, I will test it also +on linux/alpha. + + +Encodings +********* + +Use `FT_Get_BDF_Charset_ID' to access the encoding and registry. + +The driver always exports `ft_encoding_none' as face->charmap.encoding. +FT_Get_Char_Index() behavior is unmodified, that is, it converts the ULong +value given as argument into the corresponding glyph number. + + +Known problems +************** + +- dealing explicitly with encodings breaks the uniformity of FreeType 2 + API. + +- except for encodings properties, client applications have no + visibility of the PCF_Face object. This means that applications + cannot directly access font tables and are obliged to trust + FreeType. + +- currently, glyph names and ink_metrics are ignored. + +I plan to give full visibility of the PCF_Face object in the next +release of the driver, thus implementing also glyph names and +ink_metrics. + +- height is defined as (ascent - descent). Is this correct? + +- if unable to read size information from the font, PCF_Init_Face + sets available_size->width and available_size->height to 12. + +- too many english grammar errors in the readme file :-( + + +License +******* + +Copyright (C) 2000 by Francesco Zappa Nardelli + +Permission is hereby granted, free of charge, to any person obtaining +a copy of this software and associated documentation files (the +"Software"), to deal in the Software without restriction, including +without limitation the rights to use, copy, modify, merge, publish, +distribute, sublicense, and/or sell copies of the Software, and to +permit persons to whom the Software is furnished to do so, subject to +the following conditions: + +The above copyright notice and this permission notice shall be +included in all copies or substantial portions of the Software. + +THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, +EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF +MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. +IN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY +CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, +TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE +SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE. + + +Credits +******* + +Keith Packard wrote the pcf driver found in XFree86.

Each + * profile is simply an array of scanline intersections on a given + * dimension. A profile's main attributes are + * + * o its scanline position boundaries, i.e. `Ymin' and `Ymax' + * + * o an array of intersection coordinates for each scanline + * between `Ymin' and `Ymax' + * + * o a direction, indicating whether it was built going `up' or + * `down', as this is very important for filling rules + * + * o its drop-out mode + * + * 2 - Sweeping the target map's scanlines in order to compute segment + * `spans' which are then filled. Additionally, this pass + * performs drop-out control. + * + * The outline data is parsed during step 1 only. The profiles are + * built from the bottom of the render pool, used as a stack. The + * following graphics shows the profile list under construction: + * + * __________________________________________________________ _ _ + * | | | | | + * | profile | coordinates for | profile | coordinates for |--> + * | 1 | profile 1 | 2 | profile 2 |--> + * |_________|_________________|_________|_________________|__ _ _ + * + * ^ ^ + * | | + * start of render pool top + * + * The top of the profile stack is kept in the `top' variable. + * + * As you can see, a profile record is pushed on top of the render + * pool, which is then followed by its coordinates/intersections. If + * a change of direction is detected in the outline, a new profile is + * generated until the end of the outline. + * + * Note that when all profiles have been generated, the function + * Finalize_Profile_Table() is used to record, for each profile, its + * bottom-most scanline as well as the scanline above its upmost + * boundary. These positions are called `y-turns' because they (sort + * of) correspond to local extrema. They are stored in a sorted list + * built from the top of the render pool as a downwards stack: + * + * _ _ _______________________________________ + * | | + * <--| sorted list of | + * <--| extrema scanlines | + * _ _ __________________|____________________| + * + * ^ ^ + * | | + * maxBuff sizeBuff = end of pool + * + * This list is later used during the sweep phase in order to + * optimize performance (see technical note on the sweep below). + * + * Of course, the raster detects whether the two stacks collide and + * handles the situation properly. + * + */ + + + /*************************************************************************/ + /*************************************************************************/ + /** **/ + /** CONFIGURATION MACROS **/ + /** **/ + /*************************************************************************/ + /*************************************************************************/ + + + /*************************************************************************/ + /*************************************************************************/ + /** **/ + /** OTHER MACROS (do not change) **/ + /** **/ + /*************************************************************************/ + /*************************************************************************/ + + /************************************************************************** + * + * The macro FT_COMPONENT is used in trace mode.

There is another + * renderer called 'sdf', which generates SDF directly from outlines; + * see file `ftsdf.c` for more. + * + * * The idea of generating SDF from bitmaps is taken from two research + * papers, where one is dependent on the other: + * + * - Per-Erik Danielsson: Euclidean Distance Mapping + * http://webstaff.itn.liu.se/~stegu/JFA/Danielsson.pdf + * + * From this paper we use the eight-point sequential Euclidean + * distance mapping (8SED). This is the heart of the process used + * in this rasterizer. + * + * - Stefan Gustavson, Robin Strand: Anti-aliased Euclidean distance transform. + * http://weber.itn.liu.se/~stegu/aadist/edtaa_preprint.pdf + * + * The original 8SED algorithm discards the pixels' alpha values, + * which can contain information about the actual outline of the + * glyph. This paper takes advantage of those alpha values and + * approximates outline pretty accurately. + * + * * This rasterizer also works for monochrome bitmaps. However, the + * result is not as accurate since we don't have any way to + * approximate outlines from binary bitmaps. + * + * ======================================================================== + * + * Generating SDF from bitmap is done in several steps. + * + * (1) The only information we have is the bitmap itself. It can + * be monochrome or anti-aliased. If it is anti-aliased, pixel values + * are nothing but coverage values. These coverage values can be used + * to extract information about the outline of the image. For + * example, if the pixel's alpha value is 0.5, then we can safely + * assume that the outline passes through the center of the pixel. + * + * (2) Find edge pixels in the bitmap (see `bsdf_is_edge` for more). For + * all edge pixels we use the Anti-aliased Euclidean distance + * transform algorithm and compute approximate edge distances (see + * `compute_edge_distance` and/or the second paper for more). + * + * (3) Now that we have computed approximate distances for edge pixels we + * use the 8SED algorithm to basically sweep the entire bitmap and + * compute distances for the rest of the pixels. (Since the algorithm + * is pretty convoluted it is only explained briefly in a comment to + * function `edt8`. To see the actual algorithm refer to the first + * paper.) + * + * (4) Finally, compute the sign for each pixel. This is done in function + * `finalize_sdf`. The basic idea is that if a pixel's original + * alpha/coverage value is greater than 0.5 then it is 'inside' (and + * 'outside' otherwise). + * + * Pseudo Code: + * + * ``` + * b = source bitmap; + * t = target bitmap; + * dm = list of distances; // dimension equal to b + * + * foreach grid_point (x, y) in b: + * { + * if (is_edge(x, y)): + * dm = approximate_edge_distance(b, x, y); + * + * // do the 8SED on the distances + * edt8(dm); + * + * // determine the signs + * determine_signs(dm): + * + * // copy SDF data to the target bitmap + * copy(dm to t); + * } + * + */ + + + /************************************************************************** + * + * The macro FT_COMPONENT is used in trace mode.

There is + * another renderer called 'bsdf', which converts bitmaps to SDF; see + * file `ftbsdf.c` for more. + * + * * The basic idea of generating the SDF is taken from Viktor Chlumsky's + * research paper. The paper explains both single and multi-channel + * SDF, however, this implementation only generates single-channel SDF. + * + * Chlumsky, Viktor: Shape Decomposition for Multi-channel Distance + * Fields. Master's thesis. Czech Technical University in Prague, + * Faculty of InformationTechnology, 2015. + * + * For more information: https://github.com/Chlumsky/msdfgen + * + * ======================================================================== + * + * Generating SDF from outlines is pretty straightforward. + * + * (1) We have a set of contours that make the outline of a shape/glyph. + * Each contour comprises of several edges, with three types of edges. + * + * * line segments + * * conic Bezier curves + * * cubic Bezier curves + * + * (2) Apart from the outlines we also have a two-dimensional grid, namely + * the bitmap that is used to represent the final SDF data. + * + * (3) In order to generate SDF, our task is to find shortest signed + * distance from each grid point to the outline. The 'signed + * distance' means that if the grid point is filled by any contour + * then its sign is positive, otherwise it is negative. The pseudo + * code is as follows. + * + * ``` + * foreach grid_point (x, y): + * { + * int min_dist = INT_MAX; + * + * foreach contour in outline: + * { + * foreach edge in contour: + * { + * // get shortest distance from point (x, y) to the edge + * d = get_min_dist(x, y, edge); + * + * if (d < min_dist) + * min_dist = d; + * } + * + * bitmap[x, y] = min_dist; + * } + * } + * ``` + * + * (4) After running this algorithm the bitmap contains information about + * the shortest distance from each point to the outline of the shape. + * Of course, while this is the most straightforward way of generating + * SDF, we use various optimizations in our implementation. See the + * `sdf_generate_*' functions in this file for all details. + * + * The optimization currently used by default is subdivision; see + * function `sdf_generate_subdivision` for more. + * + * Also, to see how we compute the shortest distance from a point to + * each type of edge, check out the `get_min_distance_*' functions. + * + */ + + + /************************************************************************** + * + * The macro FT_COMPONENT is used in trace mode.

The + * algorithm used here is _very_ different from the one in the standard + * `ftraster' module. Actually, `ftgrays' computes the _exact_ + * coverage of the outline on each pixel cell by straight segments. + * + * It is based on ideas that I initially found in Raph Levien's + * excellent LibArt graphics library (see https://www.levien.com/libart + * for more information, though the web pages do not tell anything + * about the renderer; you'll have to dive into the source code to + * understand how it works). + * + * Note, however, that this is a _very_ different implementation + * compared to Raph's. Coverage information is stored in a very + * different way, and I don't use sorted vector paths. Also, it doesn't + * use floating point values. + * + * Bézier segments are flattened by splitting them until their deviation + * from straight line becomes much smaller than a pixel. Therefore, the + * pixel coverage by a Bézier curve is calculated approximately. To + * estimate the deviation, we use the distance from the control point + * to the conic chord centre or the cubic chord trisection. These + * distances vanish fast after each split. In the conic case, they vanish + * predictably and the number of necessary splits can be calculated. + * + * This renderer has the following advantages: + * + * - It doesn't need an intermediate bitmap. Instead, one can supply a + * callback function that will be called by the renderer to draw gray + * spans on any target surface. You can thus do direct composition on + * any kind of bitmap, provided that you give the renderer the right + * callback. + * + * - A perfect anti-aliaser, i.e., it computes the _exact_ coverage on + * each pixel cell by straight segments. + * + * - It performs a single pass on the outline (the `standard' FT2 + * renderer makes two passes). + * + * - It can easily be modified to render to _any_ number of gray levels + * cheaply. + * + * - For small (< 80) pixel sizes, it is faster than the standard + * renderer. + * + */ + + + /************************************************************************** + * + * The macro FT_COMPONENT is used in trace mode.

This is achieved through several hacks + * in the base (v35) interpreter, as detailed below. + * + * ClearType is an umbrella term for several rendering techniques + * employed by Microsoft's various GUI and rendering toolkit + * implementations, most importantly: subpixel rendering for using the + * RGB subpixels of LCDs to approximately triple the perceived + * resolution on the x-axis and subpixel hinting for positioning stems + * on subpixel borders. TrueType programming is explicit, i.e., fonts + * must be programmed to take advantage of ClearType's possibilities. + * + * When ClearType was introduced, it seemed unlikely that all fonts + * would be reprogrammed, so Microsoft decided to implement a backward + * compatibility mode. It employs several simple to complicated + * assumptions and tricks, many of them font-dependent, that modify the + * interpretation of the bytecode contained in these fonts to retrofit + * them into a ClearType-y look. The quality of the results varies. + * Most (web)fonts that were released since then have come to rely on + * these hacks to render correctly, even some of Microsoft's flagship + * fonts (e.g., Calibri, Cambria, Segoe UI). + * + * FreeType's minimal subpixel hinting code (interpreter version 40) + * employs a small list of font-agnostic hacks loosely based on the + * public information available on Microsoft's compatibility mode[2]. + * The focus is on modern (web)fonts rather than legacy fonts that were + * made for monochrome rendering. It will not match ClearType rendering + * exactly. Unlike the `Infinality' code (interpreter version 38) that + * came before, it will not try to toggle hacks for specific fonts for + * performance and complexity reasons. It will fall back to version 35 + * behavior for tricky fonts[1] or when monochrome rendering is + * requested. + * + * Major hacks + * + * - Any point movement on the x axis is ignored (cf. `Direct_Move' and + * `Direct_Move_X'). This has the smallest code footprint and single + * biggest effect. The ClearType way to increase resolution is + * supersampling the x axis, the FreeType way is ignoring instructions + * on the x axis, which gives the same result in the majority of + * cases. + * + * - Points are not moved post-IUP (neither on the x nor on the y axis), + * except the x component of diagonal moves post-IUP (cf. + * `Direct_Move', `Direct_Move_Y', `Move_Zp2_Point'). Post-IUP + * changes are commonly used to `fix' pixel patterns which has little + * use outside monochrome rendering. + * + * - SHPIX and DELTAP don't execute unless moving a composite on the + * y axis or moving a previously y touched point. SHPIX additionally + * denies movement on the x axis (cf. `Ins_SHPIX' and `Ins_DELTAP'). + * Both instructions are commonly used to `fix' pixel patterns for + * monochrome or Windows's GDI rendering but make little sense for + * FreeType rendering. Both can distort the outline. See [2] for + * details. + * + * - The hdmx table and modifications to phantom points are ignored. + * Bearings and advance widths remain unchanged (except rounding them + * outside the interpreter!), cf. `compute_glyph_metrics' and + * `TT_Hint_Glyph'. Letting non-native-ClearType fonts modify spacing + * might mess up spacing. + * + * Minor hacks + * + * - FLIPRGON, FLIPRGOFF, and FLIPPT don't execute post-IUP. This + * prevents dents in e.g. Arial-Regular's `D' and `G' glyphs at + * various sizes. + * + * (Post-IUP is the state after both IUP[x] and IUP[y] have been + * executed.) + * + * The best results are achieved for fonts that were from the outset + * designed with ClearType in mind, meaning they leave the x axis mostly + * alone and don't mess with the `final' outline to produce more + * pleasing pixel patterns. The harder the designer tried to produce + * very specific patterns (`superhinting') for pre-ClearType-displays, + * the worse the results. + * + * Microsoft defines a way to turn off backward compatibility and + * interpret instructions as before (called `native ClearType')[2][3]. + * The font designer then regains full control and is responsible for + * making the font work correctly with ClearType without any + * hand-holding by the interpreter or rasterizer[4]. The v40 + * interpreter assumes backward compatibility by default, which can be + * turned off the same way by executing the following in the control + * program (cf. `Ins_INSTCTRL'). + * + * #PUSH 4,3 + * INSTCTRL[] + * + * [1] Tricky fonts as FreeType defines them rely on the bytecode + * interpreter to display correctly.

There are a few exceptions, namely the encoding, font name, + * charstrings, and subrs; they are handled with a special pattern + * matching routine. + * + * All other common cases are handled very simply. The matching rules + * are defined in the file `t1tokens.h' through the use of several + * macros calls PARSE_XXX.
