- GNU LESSER GENERAL PUBLIC LICENSE
- Version 2.1, February 1999
- Copyright (C) 1991, 1999 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.
- [This is the first released version of the Lesser GPL. It also counts
- as the successor of the GNU Library Public License, version 2, hence
- the version number 2.1.]
- Preamble
- The licenses for most software are designed to take away your
- freedom to share and change it. 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.

- 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

- GNU LESSER GENERAL PUBLIC LICENSE
- Version 3, 29 June 2007
- Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
- This version of the GNU Lesser General Public License incorporates
- the terms and conditions of version 3 of the GNU General Public
- License, supplemented by the additional permissions listed below.
- 0. Additional Definitions.
- As used herein, "this License" refers to version 3 of the GNU Lesser
- General Public License, and the "GNU GPL" refers to version 3 of the GNU
- General Public License.
- "The Library" refers to a covered work governed by this License,
- other than an Application or a Combined Work as defined below.
- An "Application" is any work that makes use of an interface provided
- by the Library, but which is not otherwise based on the Library.
- Defining a subclass of a class defined by the Library is deemed a mode
- of using an interface provided by the Library.
- A "Combined Work" is a work produced by combining or linking an
- Application with the Library. The particular version of the Library
- with which the Combined Work was made is also called the "Linked
- Version".
- The "Minimal Corresponding Source" for a Combined Work means the
- Corresponding Source for the Combined Work, excluding any source code
- for portions of the Combined Work that, considered in isolation, are
- based on the Application, and not on the Linked Version.
- The "Corresponding Application Code" for a Combined Work means the
- object code and/or source code for the Application, including any data
- and utility programs needed for reproducing the Combined Work from the
- Application, but excluding the System Libraries of the Combined Work.
- 1. Exception to Section 3 of the GNU GPL.
- You may convey a covered work under sections 3 and 4 of this License
- without being bound by section 3 of the GNU GPL.
- 2. Conveying Modified Versions.
- If you modify a copy of the Library, and, in your modifications, a
- facility refers to a function or data to be supplied by an Application
- that uses the facility (other than as an argument passed when the
- facility is invoked), then you may convey a copy of the modified
- version:
- a) under this License, provided that you make a good faith effort to
- ensure that, in the event an Application does not supply the
- function or data, the facility still operates, and performs
- whatever part of its purpose remains meaningful, or
- b) under the GNU GPL, with none of the additional permissions of
- this License applicable to that copy.
- 3. Object Code Incorporating Material from Library Header Files.
- The object code form of an Application may incorporate material from
- a header file that is part of the Library. You may convey such object
- code under terms of your choice, provided that, if the incorporated
- material is not limited to numerical parameters, data structure
- layouts and accessors, or small macros, inline functions and templates
- (ten or fewer lines in length), you do both of the following:
- a) Give prominent notice with each copy of the object code that the
- Library is used in it and that the Library and its use are
- covered by this License.
- b) Accompany the object code with a copy of the GNU GPL and this license
- document.
- 4. Combined Works.
- You may convey a Combined Work under terms of your choice that,
- taken together, effectively do not restrict modification of the
- portions of the Library contained in the Combined Work and reverse
- engineering for debugging such modifications, if you also do each of
- the following:
- a) Give prominent notice with each copy of the Combined Work that
- the Library is used in it and that the Library and its use are
- covered by this License.
- b) Accompany the Combined Work with a copy of the GNU GPL and this license
- document.
- c) For a Combined Work that displays copyright notices during
- execution, include the copyright notice for the Library among
- these notices, as well as a reference directing the user to the
- copies of the GNU GPL and this license document.
- d) Do one of the following:
- 0) Convey the Minimal Corresponding Source under the terms of this
- License, and the Corresponding Application Code in a form
- suitable for, and under terms that permit, the user to
- recombine or relink the Application with a modified version of
- the Linked Version to produce a modified Combined Work, in the
- manner specified by section 6 of the GNU GPL for conveying
- Corresponding Source.
- 1) Use a suitable shared library mechanism for linking with the
- Library. A suitable mechanism is one that (a) uses at run time
- a copy of the Library already present on the user's computer
- system, and (b) will operate properly with a modified version
- of the Library that is interface-compatible with the Linked
- Version.
- e) Provide Installation Information, but only if you would otherwise
- be required to provide such information under section 6 of the
- GNU GPL, and only to the extent that such information is
- necessary to install and execute a modified version of the
- Combined Work produced by recombining or relinking the
- Application with a modified version of the Linked Version. (If
- you use option 4d0, the Installation Information must accompany
- the Minimal Corresponding Source and Corresponding Application
- Code. If you use option 4d1, you must provide the Installation
- Information in the manner specified by section 6 of the GNU GPL
- for conveying Corresponding Source.)
- 5. Combined Libraries.
- 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 that are not Applications and are not covered by this
- License, and convey such a combined library under terms of your
- choice, if you do both of the following:
- a) Accompany the combined library with a copy of the same work based
- on the Library, uncombined with any other library facilities,
- conveyed under the terms of this License.
- b) Give prominent notice with the combined library that part of it
- is a work based on the Library, and explaining where to find the
- accompanying uncombined form of the same work.
- 6. Revised Versions of the GNU Lesser General Public License.
- The Free Software Foundation may publish revised and/or new versions
- of the GNU 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 as you received it specifies that a certain numbered version
- of the GNU Lesser General Public License "or any later version"
- applies to it, you have the option of following the terms and
- conditions either of that published version or of any later version
- published by the Free Software Foundation. If the Library as you
- received it does not specify a version number of the GNU Lesser
- General Public License, you may choose any version of the GNU Lesser
- General Public License ever published by the Free Software Foundation.
- If the Library as you received it specifies that a proxy can decide
- whether future versions of the GNU Lesser General Public License shall
- apply, that proxy's public statement of acceptance of any version is
- permanent authorization for you to choose that version for the
- Library.

- ----------------------------
- 2006-Jan-27
- Copyright 1996-2002, 2006 by
- David Turner, Robert Wilhelm, and Werner Lemberg
- Introduction
- ============
- The FreeType Project is distributed in several archive packages;
- some of them may contain, in addition to the FreeType font engine,
- various tools and contributions which rely on, or relate to, the
- FreeType Project.
- This license applies to all files found in such packages, and
- which do not fall under their own explicit license. The license
- affects thus the FreeType font engine, the test programs,
- documentation and makefiles, at the very least.
- This license was inspired by the BSD, Artistic, and IJG
- (Independent JPEG Group) licenses, which all encourage inclusion
- and use of free software in commercial and freeware products
- alike. As a consequence, its main points are that:
- o We don't promise that this software works. However, we will be
- interested in any kind of bug reports. (`as is' distribution)
- o You can use this software for whatever you want, in parts or
- full form, without having to pay us. (`royalty-free' usage)
- o You may not pretend that you wrote this software. If you use
- it, or only parts of it, in a program, you must acknowledge
- somewhere in your documentation that you have used the
- FreeType code. (`credits')
- We specifically permit and encourage the inclusion of this
- software, with or without modifications, in commercial products.
- We disclaim all warranties covering The FreeType Project and
- assume no liability related to The FreeType Project.
- Finally, many people asked us for a preferred form for a
- credit/disclaimer to use in compliance with this license. We thus
- encourage you to use the following text:
- """
- Portions of this software are copyright © <year> The FreeType
- Project (www.freetype.org). All rights reserved.
- """
- Please replace <year> with the value from the FreeType version you
- actually use.
- Legal Terms
- ===========
- 0. Definitions
- --------------
- Throughout this license, the terms `package', `FreeType Project',
- and `FreeType archive' refer to the set of files originally
- distributed by the authors (David Turner, Robert Wilhelm, and
- Werner Lemberg) as the `FreeType Project', be they named as alpha,
- beta or final release.
- `You' refers to the licensee, or person using the project, where
- `using' is a generic term including compiling the project's source
- code as well as linking it to form a `program' or `executable'.
- This program is referred to as `a program using the FreeType
- engine'.
- This license applies to all files distributed in the original
- FreeType Project, including all source code, binaries and
- documentation, unless otherwise stated in the file in its
- original, unmodified form as distributed in the original archive.
- If you are unsure whether or not a particular file is covered by
- this license, you must contact us to verify this.
- The FreeType Project is copyright (C) 1996-2000 by David Turner,
- Robert Wilhelm, and Werner Lemberg. All rights reserved except as
- specified below.
- 1. No Warranty
- --------------
- THE FREETYPE PROJECT IS PROVIDED `AS IS' WITHOUT WARRANTY OF ANY
- KIND, EITHER EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
- WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
- PURPOSE. IN NO EVENT WILL ANY OF THE AUTHORS OR COPYRIGHT HOLDERS
- BE LIABLE FOR ANY DAMAGES CAUSED BY THE USE OR THE INABILITY TO
- USE, OF THE FREETYPE PROJECT.
- 2. Redistribution
- -----------------
- This license grants a worldwide, royalty-free, perpetual and
- irrevocable right and license to use, execute, perform, compile,
- display, copy, create derivative works of, distribute and
- sublicense the FreeType Project (in both source and object code
- forms) and derivative works thereof for any purpose; and to
- authorize others to exercise some or all of the rights granted
- herein, subject to the following conditions:
- o Redistribution of source code must retain this license file
- (`FTL.TXT') unaltered; any additions, deletions or changes to
- the original files must be clearly indicated in accompanying
- documentation. The copyright notices of the unaltered,
- original files must be preserved in all copies of source
- files.
- o Redistribution in binary form must provide a disclaimer that
- states that the software is based in part of the work of the
- FreeType Team, in the distribution documentation. We also
- encourage you to put an URL to the FreeType web page in your
- documentation, though this isn't mandatory.
- These conditions apply to any software derived from or based on
- the FreeType Project, not just the unmodified files. If you use
- our work, you must acknowledge us. However, no fee need be paid
- to us.
- 3. Advertising
- --------------
- Neither the FreeType authors and contributors nor you shall use
- the name of the other for commercial, advertising, or promotional
- purposes without specific prior written permission.
- We suggest, but do not require, that you use one or more of the
- following phrases to refer to this software in your documentation
- or advertising materials: `FreeType Project', `FreeType Engine',
- `FreeType library', or `FreeType Distribution'.
- As you have not signed this license, you are not required to
- accept it. However, as the FreeType Project is copyrighted
- material, only this license, or another one contracted with the
- authors, grants you the right to use, distribute, and modify it.
- Therefore, by using, distributing, or modifying the FreeType
- Project, you indicate that you understand and accept all the terms
- of this license.
- 4. Contacts
- -----------
- There are two mailing lists related to FreeType:
- o freetype@nongnu.org
- Discusses general use and applications of FreeType, as well as
- future and wanted additions to the library and distribution.
- If you are looking for support, start in this list if you
- haven't found anything to help you in the documentation.
- o freetype-devel@nongnu.org
- Discusses bugs, as well as engine internals, design issues,
- specific licenses, porting, etc.

- distribution or licensing of Covered Software under this License.
- Notwithstanding Section 2.1(b) above, no patent license is granted by a
- Contributor:
- (a) for any code that a Contributor has removed from Covered Software;
- or

- or logos of any Contributor (except as may be necessary to comply with
- the notice requirements in Section 3.4).
- 2.4. Subsequent Licenses

- applicable copyright doctrines of fair use, fair dealing, or other
- equivalents.
- 2.7. Conditions
- Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
- in Section 2.1.
- 3. Responsibilities
- -------------------
- 3.1. Distribution of Source Form
- All distribution of Covered Software in Source Code Form, including any
- Modifications that You create or to which You contribute, must be under
- the terms of this License. You must inform recipients that the Source
- Code Form of the Covered Software is governed by the terms of this
- License, and how they can obtain a copy of this License. You may not
- attempt to alter or restrict the recipients' rights in the Source Code
- Form.
- 3.2. Distribution of Executable Form
- If You distribute Covered Software in Executable Form then:
- (a) such Covered Software must also be made available in Source Code
- Form, as described in Section 3.1, and You must inform recipients of
- the Executable Form how they can obtain a copy of such Source Code
- Form by reasonable means in a timely manner, at a charge no more
- than the cost of distribution to the recipient; and
- (b) You may distribute such Executable Form under the terms of this
- License, or sublicense it under different terms, provided that the
- license for the Executable Form does not attempt to limit or alter
- the recipients' rights in the Source Code Form under this License.
- 3.3. Distribution of a Larger Work
- You may create and distribute a Larger Work under terms of Your choice,
- provided that You also comply with the requirements of this License for
- the Covered Software. If the Larger Work is a combination of Covered
- Software with a work governed by one or more Secondary Licenses, and the
- Covered Software is not Incompatible With Secondary Licenses, this
- License permits You to additionally distribute such Covered Software
- under the terms of such Secondary License(s), so that the recipient of
- the Larger Work may, at their option, further distribute the Covered
- Software under the terms of either this License or such Secondary
- License(s).
- 3.4. Notices
- You may not remove or alter the substance of any license notices
- (including copyright notices, patent notices, disclaimers of warranty,
- or limitations of liability) contained within the Source Code Form of
- the Covered Software, except that You may alter any license notices to
- the extent required to remedy known factual inaccuracies.
- 3.5. Application of Additional Terms
- You may choose to offer, and to charge a fee for, warranty, support,
- indemnity or liability obligations to one or more recipients of Covered
- Software. However, You may do so only on Your own behalf, and not on
- behalf of any Contributor. You must make it absolutely clear that any
- such warranty, support, indemnity, or liability obligation is offered by
- You alone, and You hereby agree to indemnify every Contributor for any
- liability incurred by such Contributor as a result of warranty, support,
- indemnity or liability terms You offer. You may include additional
- disclaimers of warranty and limitations of liability specific to any
- jurisdiction.
- 4. Inability to Comply Due to Statute or Regulation
- ---------------------------------------------------
- If it is impossible for You to comply with any of the terms of this
- License with respect to some or all of the Covered Software due to
- statute, judicial order, or regulation then You must: (a) comply with
- the terms of this License to the maximum extent possible; and (b)
- describe the limitations and the code they affect. Such description must
- be placed in a text file included with all distributions of the Covered
- Software under this License. Except to the extent prohibited by statute
- or regulation, such description must be sufficiently detailed for a
- recipient of ordinary skill to be able to understand it.
- 5. Termination
- --------------
- 5.1. The rights granted under this License will terminate automatically
- if You fail to comply with any of its terms. However, if You become
- compliant, then the rights granted under this License from a particular
- Contributor are reinstated (a) provisionally, unless and until such
- Contributor explicitly and finally terminates Your grants, and (b) on an
- ongoing basis, if such Contributor fails to notify You of the
- non-compliance by some reasonable means prior to 60 days after You have
- come back into compliance. Moreover, Your grants from a particular
- Contributor are reinstated on an ongoing basis if such Contributor
- notifies You of the non-compliance by some reasonable means, this is the
- first time You have received notice of non-compliance with this License
- from such Contributor, and You become compliant prior to 30 days after
- Your receipt of the notice.
- 5.2. If You initiate litigation against any entity by asserting a patent
- infringement claim (excluding declaratory judgment actions,
- counter-claims, and cross-claims) alleging that a Contributor Version
- directly or indirectly infringes any patent, then the rights granted to
- You by any and all Contributors for the Covered Software under Section
- 2.1 of this License shall terminate.
- 5.3. In the event of termination under Sections 5.1 or 5.2 above, all
- end user license agreements (excluding distributors and resellers) which
- have been validly granted by You or Your distributors under this License
- prior to termination shall survive termination.
- ************************************************************************
- * *
- * 6. Disclaimer of Warranty *
- * ------------------------- *
- * *
- * Covered Software is provided under this License on an "as is" *
- * basis, without warranty of any kind, either expressed, implied, or *
- * statutory, including, without limitation, warranties that the *
- * Covered Software is free of defects, merchantable, fit for a *
- * particular purpose or non-infringing. The entire risk as to the *
- * quality and performance of the Covered Software is with You. *
- * Should any Covered Software prove defective in any respect, You *
- * (not any Contributor) assume the cost of any necessary servicing, *
- * repair, or correction. This disclaimer of warranty constitutes an *
- * essential part of this License. No use of any Covered Software is *
- * authorized under this License except under this disclaimer. *
- * *
- ************************************************************************
- ************************************************************************
- * *
- * 7. Limitation of Liability *
- * -------------------------- *
- * *
- * Under no circumstances and under no legal theory, whether tort *
- * (including negligence), contract, or otherwise, shall any *
- * Contributor, or anyone who distributes Covered Software as *
- * permitted above, be liable to You for any direct, indirect, *
- * special, incidental, or consequential damages of any character *
- * including, without limitation, damages for lost profits, loss of *
- * goodwill, work stoppage, computer failure or malfunction, or any *
- * and all other commercial damages or losses, even if such party *
- * shall have been informed of the possibility of such damages. This *
- * limitation of liability shall not apply to liability for death or *
- * personal injury resulting from such party's negligence to the *
- * extent applicable law prohibits such limitation. Some *
- * jurisdictions do not allow the exclusion or limitation of *
- * incidental or consequential damages, so this exclusion and *
- * limitation may not apply to You. *
- * *
- ************************************************************************
- 8. Litigation
- -------------
- Any litigation relating to this License may be brought only in the
- courts of a jurisdiction where the defendant maintains its principal
- place of business and such litigation shall be governed by laws of that
- jurisdiction, without reference to its conflict-of-law provisions.
- Nothing in this Section shall prevent a party's ability to bring
- cross-claims or counter-claims.
- 9. Miscellaneous
- ----------------
- This License represents the complete agreement concerning the subject
- matter hereof. If any provision of this License is held to be
- unenforceable, such provision shall be reformed only to the extent
- necessary to make it enforceable. Any law or regulation which provides
- that the language of a contract shall be construed against the drafter
- shall not be used to construe this License against a Contributor.
- 10. Versions of the License
- ---------------------------

- Libjpeg-turbo is redistributed within all opencv-python packages as build option.
- libjpeg-turbo Licenses
- ======================
- libjpeg-turbo is covered by three compatible BSD-style open source licenses:
- - The IJG (Independent JPEG Group) License, which is listed in
- [README.ijg](README.ijg)
- This license applies to the libjpeg API library and associated programs
- (any code inherited from libjpeg, and any modifications to that code.)
- - The Modified (3-clause) BSD License, which is listed below
- This license covers the TurboJPEG API library and associated programs, as
- well as the build system.
- - The [zlib License](https://opensource.org/licenses/Zlib)
- This license is a subset of the other two, and it covers the libjpeg-turbo
- SIMD extensions.
- Complying with the libjpeg-turbo Licenses
- =========================================
- This section provides a roll-up of the libjpeg-turbo licensing terms, to the
- best of our understanding.
- 1. If you are distributing a modified version of the libjpeg-turbo source,
- then:
- 1. You cannot alter or remove any existing copyright or license notices
- from the source.
- **Origin**
- - Clause 1 of the IJG License
- - Clause 1 of the Modified BSD License
- - Clauses 1 and 3 of the zlib License
- 2. You must add your own copyright notice to the header of each source
- file you modified, so others can tell that you modified that file (if
- there is not an existing copyright header in that file, then you can
- simply add a notice stating that you modified the file.)
- **Origin**
- - Clause 1 of the IJG License
- - Clause 2 of the zlib License
- 3. You must include the IJG README file, and you must not alter any of the
- copyright or license text in that file.
- **Origin**
- - Clause 1 of the IJG License
- 2. If you are distributing only libjpeg-turbo binaries without the source, or
- if you are distributing an application that statically links with
- libjpeg-turbo, then:
- 1. Your product documentation must include a message stating:
- This software is based in part on the work of the Independent JPEG
- Group.
- **Origin**
- - Clause 2 of the IJG license
- 2. If your binary distribution includes or uses the TurboJPEG API, then
- your product documentation must include the text of the Modified BSD
- License (see below.)
- **Origin**
- - Clause 2 of the Modified BSD License
- 3. You cannot use the name of the IJG or The libjpeg-turbo Project or the
- contributors thereof in advertising, publicity, etc.
- **Origin**
- - IJG License
- - Clause 3 of the Modified BSD License
- 4. The IJG and The libjpeg-turbo Project do not warrant libjpeg-turbo to be
- free of defects, nor do we accept any liability for undesirable
- consequences resulting from your use of the software.
- **Origin**
- - IJG License
- - Modified BSD License
- - zlib License
- The Modified (3-clause) BSD License

- and/or other materials provided with the distribution.

- contributors may be used to endorse or promote products derived from this
- software without specific prior written permission.

- CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE)
- ARISING IN ANY WAY OUT OF THE USE OF THIS SOFTWARE, EVEN IF ADVISED OF THE
- POSSIBILITY OF SUCH DAMAGE.
- Why Three Licenses?
- ===================
- The zlib License could have been used instead of the Modified (3-clause) BSD
- License, and since the IJG License effectively subsumes the distribution
- conditions of the zlib License, this would have effectively placed
- libjpeg-turbo binary distributions under the IJG License. However, the IJG
- License specifically refers to the Independent JPEG Group and does not extend
- attribution and endorsement protections to other entities. Thus, it was
- desirable to choose a license that granted us the same protections for new code
- that were granted to the IJG for code derived from their software.

- 3. You may not pretend that you wrote this software. If you use it in a

- you've used the IJG code.
- In legalese:
- The authors make NO WARRANTY or representation, either express or implied,
- with respect to this software, its quality, accuracy, merchantability, or

- (1) If any part of the source code for this software is distributed, then this
- README file must be included, with this copyright and no-warranty notice
- unaltered; and any additions, deletions, or changes to the original files
- must be clearly indicated in accompanying documentation.
- (2) If only executable code is distributed, then the accompanying
- documentation must state that "this software is based in part on the work of
- the Independent JPEG Group".
- (3) Permission for use of this software is granted only if the user accepts
- full responsibility for any undesirable consequences; the authors accept
- NO LIABILITY for damages of any kind.
- These conditions apply to any software derived from or based on the IJG code,
- not just to the unmodified library. If you use our work, you ought to

- Permission is NOT granted for the use of any IJG author's name or company name

- The Unix configuration script "configure" was produced with GNU Autoconf.
- It is copyright by the Free Software Foundation but is freely distributable.
- The same holds for its supporting scripts (config.guess, config.sub,
- ltmain.sh). Another support script, install-sh, is copyright by X Consortium
- but is also freely distributable.
- The IJG distribution formerly included code to read and write GIF files.
- To avoid entanglement with the Unisys LZW patent, GIF reading support has
- been removed altogether, and the GIF writer has been simplified to produce
- "uncompressed GIFs". This technique does not use the LZW algorithm; the
- resulting GIF files are larger than usual, but are readable by all standard
- GIF decoders.
- We are required to state that
- "The Graphics Interchange Format(c) is the Copyright property of
- CompuServe Incorporated. GIF(sm) is a Service Mark property of
- CompuServe Incorporated."
