   6 ```
   7 FreeType comes with two licenses from which you can choose the one
   8 which fits your needs best.
   9 
  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
  13     GPL version 2.
  14 
  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.

  33 Introduction
  34 ============
  35 
  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
  39   FreeType Project.
  40 
  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.
  45 
  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:
  50 
  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)
  53 
  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)
  56 
  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')
  61 
  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.
  66 
  67 
  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:
  71 
  72    """
  73     Portions of this software are copyright © <year> The FreeType
  74     Project (www.freetype.org).  All rights reserved.
  75    """
  76 
  77   Please replace <year> with the value from the FreeType version you
  78   actually use.

  80 
  81 Legal Terms
  82 ===========
  83 
  84 0. Definitions
  85 --------------
  86 
  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.
  92 
  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
  97   engine'.
  98 
  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.
 105 
 106   The FreeType  Project is copyright (C) 1996-2000  by David Turner,
 107   Robert Wilhelm, and Werner Lemberg.  All rights reserved except as
 108   specified below.
 109 
 110 1. No Warranty
 111 --------------
 112 
 113   THE FREETYPE PROJECT  IS PROVIDED `AS IS' WITHOUT  WARRANTY OF ANY
 114   KIND, EITHER  EXPRESS OR IMPLIED,  INCLUDING, BUT NOT  LIMITED TO,
 115   WARRANTIES  OF  MERCHANTABILITY   AND  FITNESS  FOR  A  PARTICULAR
 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.
 119 
 120 2. Redistribution
 121 -----------------
 122 
 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:
 130 
 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
 136       files.
 137 
 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.
 143 
 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
 147   to us.
 148 
 149 3. Advertising
 150 --------------
 151 
 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.
 155 
 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'.
 160 
 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
 167   of this license.

 193 
 194 ```
 195                     GNU GENERAL PUBLIC LICENSE
 196                        Version 2, June 1991
 197 
 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.
 202 
 203                             Preamble
 204 
 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
 213 your programs, too.
 214 
 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.
 221 
 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.
 226 
 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
 231 rights.
 232 
 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.
 236 
 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.
 243 
 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.
 249 
 250   The precise terms and conditions for copying, distribution and
 251 modification follow.
 252 
 253                     GNU GENERAL PUBLIC LICENSE
 254    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
 255 
 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".
 265 
 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.
 272 
 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.
 280 
 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.
 283 
 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:
 288 
 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.
 291 
 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.
 296 
 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.)
 307 
 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.
 317 
 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.
 322 
 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.
 327 
 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:
 331 
 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,
 335 
 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,
 342 
 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.)
 348 
 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.
 359 
 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.
 365 
 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.
 373 
 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.
 382 
 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
 389 this License.
 390 
 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.
 403 
 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
 407 circumstances.
 408 
 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
 418 impose that choice.
 419 
 420 This section is intended to make thoroughly clear what is believed to
 421 be a consequence of the rest of this License.
 422 
 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.
 430 
 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.
 435 
 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
 442 Foundation.
 443 
 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.
 451 
 452                             NO WARRANTY
 453 
 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.
 463 
 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

 476             How to Apply These Terms to Your New Programs
 477 
 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.
 481 
 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.
 486 
 487     <one line to give the program's name and a brief idea of what it does.>
 488     Copyright (C) <year>  <name of author>
 489 
 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.
 494 
 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.
 499 
 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
 503 
 504 
 505 Also add information on how to contact you by electronic and paper mail.
 506 
 507 If the program is interactive, make it output a short notice like this
 508 when it starts in an interactive mode:
 509 
 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.
 514 
 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.
 519 
 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:
 523 
 524   Yoyodyne, Inc., hereby disclaims all copyright interest in the program
 525   `Gnomovision' (which makes passes at compilers) written by James Hacker.

 529 
 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.
