1 ## The FreeType Project: Freetype v2.9.1
7 FreeType comes with two licenses from which you can choose the one
8 which fits your needs best.
10 The FreeType License (FTL) is the most commonly used one. It is
11 a BSD-style license with a credit clause and thus compatible with
12 the GNU Public License (GPL) version 3, but not with the
15 The GNU General Public License (GPL), version 2. Use it for all
16 projects which use the GPLv2 also, or which need a license
17 compatible to the GPLv2.
23 The FreeType Project LICENSE
24 ----------------------------
28 Copyright 1996-2002, 2006 by
29 David Turner, Robert Wilhelm, and Werner Lemberg
36 The FreeType Project is distributed in several archive packages;
37 some of them may contain, in addition to the FreeType font engine,
38 various tools and contributions which rely on, or relate to, the
41 This license applies to all files found in such packages, and
42 which do not fall under their own explicit license. The license
43 affects thus the FreeType font engine, the test programs,
44 documentation and makefiles, at the very least.
46 This license was inspired by the BSD, Artistic, and IJG
47 (Independent JPEG Group) licenses, which all encourage inclusion
48 and use of free software in commercial and freeware products
49 alike. As a consequence, its main points are that:
51 o We don't promise that this software works. However, we will be
52 interested in any kind of bug reports. (`as is' distribution)
54 o You can use this software for whatever you want, in parts or
55 full form, without having to pay us. (`royalty-free' usage)
57 o You may not pretend that you wrote this software. If you use
58 it, or only parts of it, in a program, you must acknowledge
59 somewhere in your documentation that you have used the
60 FreeType code. (`credits')
62 We specifically permit and encourage the inclusion of this
63 software, with or without modifications, in commercial products.
64 We disclaim all warranties covering The FreeType Project and
65 assume no liability related to The FreeType Project.
68 Finally, many people asked us for a preferred form for a
69 credit/disclaimer to use in compliance with this license. We thus
70 encourage you to use the following text:
73 Portions of this software are copyright © <year> The FreeType
74 Project (www.freetype.org). All rights reserved.
77 Please replace <year> with the value from the FreeType version you
87 Throughout this license, the terms `package', `FreeType Project',
88 and `FreeType archive' refer to the set of files originally
89 distributed by the authors (David Turner, Robert Wilhelm, and
90 Werner Lemberg) as the `FreeType Project', be they named as alpha,
91 beta or final release.
93 `You' refers to the licensee, or person using the project, where
94 `using' is a generic term including compiling the project's source
95 code as well as linking it to form a `program' or `executable'.
96 This program is referred to as `a program using the FreeType
99 This license applies to all files distributed in the original
100 FreeType Project, including all source code, binaries and
101 documentation, unless otherwise stated in the file in its
102 original, unmodified form as distributed in the original archive.
103 If you are unsure whether or not a particular file is covered by
104 this license, you must contact us to verify this.

116 PURPOSE. IN NO EVENT WILL ANY OF THE AUTHORS OR COPYRIGHT HOLDERS
117 BE LIABLE FOR ANY DAMAGES CAUSED BY THE USE OR THE INABILITY TO
118 USE, OF THE FREETYPE PROJECT.
123 This license grants a worldwide, royalty-free, perpetual and
124 irrevocable right and license to use, execute, perform, compile,
125 display, copy, create derivative works of, distribute and
126 sublicense the FreeType Project (in both source and object code
127 forms) and derivative works thereof for any purpose; and to
128 authorize others to exercise some or all of the rights granted
129 herein, subject to the following conditions:
131 o Redistribution of source code must retain this license file
132 (`FTL.TXT') unaltered; any additions, deletions or changes to
133 the original files must be clearly indicated in accompanying
134 documentation. The copyright notices of the unaltered,
135 original files must be preserved in all copies of source
138 o Redistribution in binary form must provide a disclaimer that
139 states that the software is based in part of the work of the
140 FreeType Team, in the distribution documentation. We also
141 encourage you to put an URL to the FreeType web page in your
142 documentation, though this isn't mandatory.
144 These conditions apply to any software derived from or based on
145 the FreeType Project, not just the unmodified files. If you use
146 our work, you must acknowledge us. However, no fee need be paid
152 Neither the FreeType authors and contributors nor you shall use
153 the name of the other for commercial, advertising, or promotional
154 purposes without specific prior written permission.
156 We suggest, but do not require, that you use one or more of the
157 following phrases to refer to this software in your documentation
158 or advertising materials: `FreeType Project', `FreeType Engine',
159 `FreeType library', or `FreeType Distribution'.
161 As you have not signed this license, you are not required to
162 accept it. However, as the FreeType Project is copyrighted
163 material, only this license, or another one contracted with the
164 authors, grants you the right to use, distribute, and modify it.
165 Therefore, by using, distributing, or modifying the FreeType
166 Project, you indicate that you understand and accept all the terms
172 There are two mailing lists related to FreeType:
174 o freetype@nongnu.org
176 Discusses general use and applications of FreeType, as well as
177 future and wanted additions to the library and distribution.
178 If you are looking for support, start in this list if you
179 haven't found anything to help you in the documentation.
181 o freetype-devel@nongnu.org
183 Discusses bugs, as well as engine internals, design issues,
184 specific licenses, porting, etc.

195 GNU GENERAL PUBLIC LICENSE
198 Copyright (C) 1989, 1991 Free Software Foundation, Inc.
199 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
200 Everyone is permitted to copy and distribute verbatim copies
201 of this license document, but changing it is not allowed.
205 The licenses for most software are designed to take away your
206 freedom to share and change it. By contrast, the GNU General Public
207 License is intended to guarantee your freedom to share and change free
208 software--to make sure the software is free for all its users. This
209 General Public License applies to most of the Free Software
210 Foundation's software and to any other program whose authors commit to
211 using it. (Some other Free Software Foundation software is covered by
212 the GNU Library General Public License instead.) You can apply it to
215 When we speak of free software, we are referring to freedom, not
216 price. Our General Public Licenses are designed to make sure that you
217 have the freedom to distribute copies of free software (and charge for
218 this service if you wish), that you receive source code or can get it
219 if you want it, that you can change the software or use pieces of it
220 in new free programs; and that you know you can do these things.
222 To protect your rights, we need to make restrictions that forbid
223 anyone to deny you these rights or to ask you to surrender the rights.
224 These restrictions translate to certain responsibilities for you if you
225 distribute copies of the software, or if you modify it.
227 For example, if you distribute copies of such a program, whether
228 gratis or for a fee, you must give the recipients all the rights that
229 you have. You must make sure that they, too, receive or can get the
230 source code. And you must show them these terms so they know their
233 We protect your rights with two steps: (1) copyright the software, and
234 (2) offer you this license which gives you legal permission to copy,
235 distribute and/or modify the software.
237 Also, for each author's protection and ours, we want to make certain
238 that everyone understands that there is no warranty for this free
239 software. If the software is modified by someone else and passed on, we
240 want its recipients to know that what they have is not the original, so
241 that any problems introduced by others will not reflect on the original
242 authors' reputations.
244 Finally, any free program is threatened constantly by software
245 patents. We wish to avoid the danger that redistributors of a free
246 program will individually obtain patent licenses, in effect making the
247 program proprietary. To prevent this, we have made it clear that any
248 patent must be licensed for everyone's free use or not licensed at all.
250 The precise terms and conditions for copying, distribution and
253 GNU GENERAL PUBLIC LICENSE
254 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
256 0. This License applies to any program or other work which contains
257 a notice placed by the copyright holder saying it may be distributed
258 under the terms of this General Public License. The "Program", below,
259 refers to any such program or work, and a "work based on the Program"
260 means either the Program or any derivative work under copyright law:
261 that is to say, a work containing the Program or a portion of it,
262 either verbatim or with modifications and/or translated into another
263 language. (Hereinafter, translation is included without limitation in
264 the term "modification".) Each licensee is addressed as "you".
266 Activities other than copying, distribution and modification are not
267 covered by this License; they are outside its scope. The act of
268 running the Program is not restricted, and the output from the Program
269 is covered only if its contents constitute a work based on the
270 Program (independent of having been made by running the Program).
271 Whether that is true depends on what the Program does.
273 1. You may copy and distribute verbatim copies of the Program's
274 source code as you receive it, in any medium, provided that you
275 conspicuously and appropriately publish on each copy an appropriate
276 copyright notice and disclaimer of warranty; keep intact all the
277 notices that refer to this License and to the absence of any warranty;
278 and give any other recipients of the Program a copy of this License
279 along with the Program.
281 You may charge a fee for the physical act of transferring a copy, and
282 you may at your option offer warranty protection in exchange for a fee.
284 2. You may modify your copy or copies of the Program or any portion
285 of it, thus forming a work based on the Program, and copy and
286 distribute such modifications or work under the terms of Section 1
287 above, provided that you also meet all of these conditions:
289 a) You must cause the modified files to carry prominent notices
290 stating that you changed the files and the date of any change.
292 b) You must cause any work that you distribute or publish, that in
293 whole or in part contains or is derived from the Program or any
294 part thereof, to be licensed as a whole at no charge to all third
295 parties under the terms of this License.
297 c) If the modified program normally reads commands interactively
298 when run, you must cause it, when started running for such
299 interactive use in the most ordinary way, to print or display an
300 announcement including an appropriate copyright notice and a
301 notice that there is no warranty (or else, saying that you provide
302 a warranty) and that users may redistribute the program under
303 these conditions, and telling the user how to view a copy of this
304 License. (Exception: if the Program itself is interactive but
305 does not normally print such an announcement, your work based on
306 the Program is not required to print an announcement.)
308 These requirements apply to the modified work as a whole. If
309 identifiable sections of that work are not derived from the Program,
310 and can be reasonably considered independent and separate works in
311 themselves, then this License, and its terms, do not apply to those
312 sections when you distribute them as separate works. But when you
313 distribute the same sections as part of a whole which is a work based
314 on the Program, the distribution of the whole must be on the terms of
315 this License, whose permissions for other licensees extend to the
316 entire whole, and thus to each and every part regardless of who wrote it.
318 Thus, it is not the intent of this section to claim rights or contest
319 your rights to work written entirely by you; rather, the intent is to
320 exercise the right to control the distribution of derivative or
321 collective works based on the Program.
323 In addition, mere aggregation of another work not based on the Program
324 with the Program (or with a work based on the Program) on a volume of
325 a storage or distribution medium does not bring the other work under
326 the scope of this License.
328 3. You may copy and distribute the Program (or a work based on it,
329 under Section 2) in object code or executable form under the terms of
330 Sections 1 and 2 above provided that you also do one of the following:
332 a) Accompany it with the complete corresponding machine-readable
333 source code, which must be distributed under the terms of Sections
334 1 and 2 above on a medium customarily used for software interchange; or,
336 b) Accompany it with a written offer, valid for at least three
337 years, to give any third party, for a charge no more than your
338 cost of physically performing source distribution, a complete
339 machine-readable copy of the corresponding source code, to be
340 distributed under the terms of Sections 1 and 2 above on a medium
341 customarily used for software interchange; or,
343 c) Accompany it with the information you received as to the offer
344 to distribute corresponding source code. (This alternative is
345 allowed only for noncommercial distribution and only if you
346 received the program in object code or executable form with such
347 an offer, in accord with Subsection b above.)
349 The source code for a work means the preferred form of the work for
350 making modifications to it. For an executable work, complete source
351 code means all the source code for all modules it contains, plus any
352 associated interface definition files, plus the scripts used to
353 control compilation and installation of the executable. However, as a
354 special exception, the source code distributed need not include
355 anything that is normally distributed (in either source or binary
356 form) with the major components (compiler, kernel, and so on) of the
357 operating system on which the executable runs, unless that component
358 itself accompanies the executable.
360 If distribution of executable or object code is made by offering
361 access to copy from a designated place, then offering equivalent
362 access to copy the source code from the same place counts as
363 distribution of the source code, even though third parties are not
364 compelled to copy the source along with the object code.
366 4. You may not copy, modify, sublicense, or distribute the Program
367 except as expressly provided under this License. Any attempt
368 otherwise to copy, modify, sublicense or distribute the Program is
369 void, and will automatically terminate your rights under this License.
370 However, parties who have received copies, or rights, from you under
371 this License will not have their licenses terminated so long as such
372 parties remain in full compliance.
374 5. You are not required to accept this License, since you have not
375 signed it. However, nothing else grants you permission to modify or
376 distribute the Program or its derivative works. These actions are
377 prohibited by law if you do not accept this License. Therefore, by
378 modifying or distributing the Program (or any work based on the
379 Program), you indicate your acceptance of this License to do so, and
380 all its terms and conditions for copying, distributing or modifying
381 the Program or works based on it.
383 6. Each time you redistribute the Program (or any work based on the
384 Program), the recipient automatically receives a license from the
385 original licensor to copy, distribute or modify the Program subject to
386 these terms and conditions. You may not impose any further
387 restrictions on the recipients' exercise of the rights granted herein.
388 You are not responsible for enforcing compliance by third parties to
391 7. If, as a consequence of a court judgment or allegation of patent
392 infringement or for any other reason (not limited to patent issues),
393 conditions are imposed on you (whether by court order, agreement or
394 otherwise) that contradict the conditions of this License, they do not
395 excuse you from the conditions of this License. If you cannot
396 distribute so as to satisfy simultaneously your obligations under this
397 License and any other pertinent obligations, then as a consequence you
398 may not distribute the Program at all. For example, if a patent
399 license would not permit royalty-free redistribution of the Program by
400 all those who receive copies directly or indirectly through you, then
401 the only way you could satisfy both it and this License would be to
402 refrain entirely from distribution of the Program.
404 If any portion of this section is held invalid or unenforceable under
405 any particular circumstance, the balance of the section is intended to
406 apply and the section as a whole is intended to apply in other
409 It is not the purpose of this section to induce you to infringe any
410 patents or other property right claims or to contest validity of any
411 such claims; this section has the sole purpose of protecting the
412 integrity of the free software distribution system, which is
413 implemented by public license practices. Many people have made
414 generous contributions to the wide range of software distributed
415 through that system in reliance on consistent application of that
416 system; it is up to the author/donor to decide if he or she is willing
417 to distribute software through any other system and a licensee cannot
420 This section is intended to make thoroughly clear what is believed to
421 be a consequence of the rest of this License.
423 8. If the distribution and/or use of the Program is restricted in
424 certain countries either by patents or by copyrighted interfaces, the
425 original copyright holder who places the Program under this License
426 may add an explicit geographical distribution limitation excluding
427 those countries, so that distribution is permitted only in or among
428 countries not thus excluded. In such case, this License incorporates
429 the limitation as if written in the body of this License.
431 9. The Free Software Foundation may publish revised and/or new versions
432 of the General Public License from time to time. Such new versions will
433 be similar in spirit to the present version, but may differ in detail to
434 address new problems or concerns.
436 Each version is given a distinguishing version number. If the Program
437 specifies a version number of this License which applies to it and "any
438 later version", you have the option of following the terms and conditions
439 either of that version or of any later version published by the Free
440 Software Foundation. If the Program does not specify a version number of
441 this License, you may choose any version ever published by the Free Software
444 10. If you wish to incorporate parts of the Program into other free
445 programs whose distribution conditions are different, write to the author
446 to ask for permission. For software which is copyrighted by the Free
447 Software Foundation, write to the Free Software Foundation; we sometimes
448 make exceptions for this. Our decision will be guided by the two goals
449 of preserving the free status of all derivatives of our free software and
450 of promoting the sharing and reuse of software generally.
454 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
455 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
456 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
457 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
458 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
459 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
460 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
461 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
462 REPAIR OR CORRECTION.
464 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
465 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
466 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
467 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
468 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
469 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
470 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
471 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
472 POSSIBILITY OF SUCH DAMAGES.
474 END OF TERMS AND CONDITIONS
476 How to Apply These Terms to Your New Programs
478 If you develop a new program, and you want it to be of the greatest
479 possible use to the public, the best way to achieve this is to make it
480 free software which everyone can redistribute and change under these terms.
482 To do so, attach the following notices to the program. It is safest
483 to attach them to the start of each source file to most effectively
484 convey the exclusion of warranty; and each file should have at least
485 the "copyright" line and a pointer to where the full notice is found.
487 <one line to give the program's name and a brief idea of what it does.>
488 Copyright (C) <year> <name of author>
490 This program is free software; you can redistribute it and/or modify
491 it under the terms of the GNU General Public License as published by
492 the Free Software Foundation; either version 2 of the License, or
493 (at your option) any later version.
495 This program is distributed in the hope that it will be useful,
496 but WITHOUT ANY WARRANTY; without even the implied warranty of
497 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
498 GNU General Public License for more details.
500 You should have received a copy of the GNU General Public License
501 along with this program; if not, write to the Free Software
502 Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
505 Also add information on how to contact you by electronic and paper mail.
507 If the program is interactive, make it output a short notice like this
508 when it starts in an interactive mode:
510 Gnomovision version 69, Copyright (C) year name of author
511 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
512 This is free software, and you are welcome to redistribute it
513 under certain conditions; type `show c' for details.
515 The hypothetical commands `show w' and `show c' should show the appropriate
516 parts of the General Public License. Of course, the commands you use may
517 be called something other than `show w' and `show c'; they could even be
518 mouse-clicks or menu items--whatever suits your program.
520 You should also get your employer (if you work as a programmer) or your
521 school, if any, to sign a "copyright disclaimer" for the program, if
522 necessary. Here is a sample; alter the names:
524 Yoyodyne, Inc., hereby disclaims all copyright interest in the program
525 `Gnomovision' (which makes passes at compilers) written by James Hacker.

530 This General Public License does not permit incorporating your program into
531 proprietary programs. If your program is a subroutine library, you may
532 consider it more useful to permit linking proprietary applications with the
533 library. If this is what you want to do, use the GNU Library General
534 Public License instead of this License.
