1 ## The FreeType Project: Freetype v2.9.1 2 3 4 ### FreeType Notice 5 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. 18 19 ``` 20 21 ### FreeType License 22 ``` 23 The FreeType Project LICENSE 24 ---------------------------- 25 26 2006-Jan-27 27 28 Copyright 1996-2002, 2006 by 29 David Turner, Robert Wilhelm, and Werner Lemberg 30 31 32 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. 79 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. 168 169 4. Contacts 170 ----------- 171 172 There are two mailing lists related to FreeType: 173 174 o freetype@nongnu.org 175 176 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. 180 181 o freetype-devel@nongnu.org 182 183 Discusses bugs, as well as engine internals, design issues, 184 specific licenses, porting, etc. 185 186 Our home page can be found at 187 188 http://www.freetype.org 189 190 ``` 191 192 ### GPL v2 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 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. 473 474 END OF TERMS AND CONDITIONS 475 476 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. 526 527 <signature of Ty Coon>, 1 April 1989 528 Ty Coon, President of Vice 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. 535 536 ``` 537
