looking at the documentation files (in roughly the order listed) before diving into the code.
OVERVIEW
This package contains C software to implement JPEG image encoding, decoding, and transcoding. JPEG
(pronounced "jay-peg") is a standardized compression method for full-color and gray-scale images.
This software implements JPEG baseline, extended-sequential, and progressive compression processes. Provision
is made for supporting all variants of these processes, although some uncommon parameter settings aren't
implemented yet. We have made no provision for supporting the hierarchical or lossless processes defined in the
standard.
We provide a set of library routines for reading and writing JPEG image files, plus two sample applications "cjpeg"
and "djpeg", which use the library to perform conversion between JPEG and some other popular image file formats.
The library is intended to be reused in other applications.
In order to support file conversion and viewing software, we have included considerable functionality beyond the bare
JPEG coding/decoding capability; for example, the color quantization modules are not strictly part of JPEG decoding,
but they are essential for output to colormapped file formats or colormapped displays. These extra functions can be
compiled out of the library if not required for a particular application.
We have also included "jpegtran", a utility for lossless transcoding between different JPEG processes, and
"rdjpgcom" and "wrjpgcom", two simple applications for inserting and extracting textual comments in JFIF files.
The emphasis in designing this software has been on achieving portability and flexibility, while also making it fast
enough to be useful. In particular, the software is not intended to be read as a tutorial on JPEG. (See the
REFERENCES section for introductory material.) Rather, it is intended to be reliable, portable, industrial-strength
code. We do not claim to have achieved that goal in every aspect of the software, but we strive for it.
We welcome the use of this software as a component of commercial products. No royalty is required, but we do ask
for an acknowledgement in product documentation, as described under LEGAL ISSUES.
LEGAL ISSUES
In plain English:
1. We don't promise that this software works. (But if you find any bugs, please let us know!)
2. You can use this software for whatever you want. You don't have to pay us.
3. You may not pretend that you wrote this software. If you use it in a program, you must acknowledge
somewhere in your documentation that you've used the IJG code.

ansi2knr.c is included in this distribution by permission of L. Peter Deutsch, sole proprietor of its copyright holder,
Aladdin Enterprises of Menlo Park, CA.ansi2knr.c is NOT covered by the above copyright and conditions, but instead
by the usual distribution terms of the Free Software Foundation; principally, that you must include source code if you
redistribute it. (See the file ansi2knr.c for full details.) However, since ansi2knr.c is not needed as part of any program
generated from the IJG code, this does not limit you more than the foregoing paragraphs do.
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."
REFERENCES
We recommend reading one or more of these references before trying to understand the innards of the JPEG
software.
The best short technical introduction to the JPEG compression algorithm is Wallace, Gregory K. "The JPEG Still
Picture Compression Standard", Communications of the ACM, April 1991 (vol. 34 no. 4), pp. 30-44. (Adjacent articles
in that issue discuss MPEG motion picture compression, applications of JPEG, and related topics.) If you don't have
the CACM issue handy, a PostScript file containing a revised version of Wallace's article is available at
http://www.ijg.org/files/wallace.ps.gz. The file (actually a preprint for an article that appeared in IEEE Trans.
Consumer Electronics) omits the sample images that appeared in CACM, but it includes corrections and some added
material. Note: the Wallace article is copyright ACM and IEEE, and it may not be used for commercial purposes.
A somewhat less technical, more leisurely introduction to JPEG can be found in "The Data Compression Book" by
Mark Nelson and Jean-loup Gailly, published by M&T Books (New York), 2nd ed. 1996, ISBN 1-55851-434-1. This
book provides good explanations and example C code for a multitude of compression methods including JPEG. It is
an excellent source if you are comfortable reading C code but don't know much about data compression in general.
The book's JPEG sample code is far from industrial-strength, but when you are ready to look at a full implementation,
you've got one here.

Polycom CMA Desktop Help Book
The best currently available description of JPEG is the textbook "JPEG Still Image Data Compression Standard" by
William B. Pennebaker and Joan L. Mitchell, published by Van Nostrand Reinhold, 1993, ISBN 0-442-01272-1. Price
US$59.95, 638 pp. The book includes the complete text of the ISO JPEG standards (DIS 10918-1 and draft DIS
10918-2).
Although this is by far the most detailed and comprehensive exposition of JPEG publicly available, we point out that it
is still missing an explanation of the most essential properties and algorithms of the underlying DCT technology. If
you think that you know about DCT-based JPEG after reading this book, then you are in delusion. The real
fundamentals and corresponding potential of DCT-based JPEG are not publicly known so far, and that is the reason
for all the mistaken developments taking place in the image coding domain.
The original JPEG standard is divided into two parts, Part 1 being the actual specification, while Part 2 covers
compliance testing methods. Part 1 is titled "Digital Compression and Coding of Continuous-tone Still Images, Part 1:
Requirements and guidelines" and has document numbers ISO/IEC IS 10918-1, ITU-T T.81. Part 2 is titled "Digital
Compression and Coding of Continuous-tone Still Images, Part 2: Compliance testing" and has document numbers
ISO/IEC IS 10918-2, ITU-T T.83.
IJG JPEG 8 introduces an implementation of the JPEG SmartScale extension which is specified in a contributed
document at ITU and ISO with title "ITU-T JPEG-Plus Proposal for Extending ITU-T T.81 for Advanced Image
Coding", April 2006, Geneva, Switzerland. The latest version of the document is Revision 3.
The JPEG standard does not specify all details of an interchangeable file format. For the omitted details we follow
the "JFIF" conventions, revision 1.02. JFIF 1.02 has been adopted as an Ecma International Technical Report and
thus received a formal publication status. It is available as a free download in PDF format from http://www.ecma-
international.org/publications/techreports/E-TR-098.htm.
A PostScript version of the JFIF document is available at
the figures.
The TIFF 6.0 file format specification can be obtained by FTP from ftp://ftp.sgi.com/graphics/tiff/TIFF6.ps.gz. The
JPEG incorporation scheme found in the TIFF 6.0 spec of 3-June-92 has a number of serious problems.
IJG does not recommend use of the TIFF 6.0 design (TIFF Compression tag 6). Instead, we recommend the JPEG
design proposed by TIFF Technical Note #2 (Compression tag 7). Copies of this Note can be obtained from
http://www.ijg.org/files/. It is expected that the next revision of the TIFF spec will replace the 6.0 JPEG design with
the Note's design. Although IJG's own code does not support TIFF/JPEG, the free libtiff library uses our library to
implement TIFF/JPEG per the Note.

FILE FORMAT WARS
The ISO JPEG standards committee actually promotes different formats like "JPEG 2000" or "JPEG XR" which are
incompatible with original DCT-based JPEG and which are based on faulty technologies. IJG therefore does not and
will not support such momentary mistakes (see REFERENCES).
We have little or no sympathy for the promotion of these formats. Indeed, one of the original reasons for developing
this free software was to help force convergence on common, interoperable format standards for JPEG files.
Don't use an incompatible file format!
(In any case, our decoder will remain capable of reading existing JPEG image files indefinitely.)
TO DO
Version 8 is the first release of a new generation JPEG standard to overcome the limitations of the original JPEG
specification.

the copyright owner that is granting the License. "Legal Entity" shall mean the union of the acting entity and
all other entities that control, are controlled by, or are under common control with that entity. For the
purposes of this definition, "control" means (i) the power, direct or indirect, to cause the direction or
management of such entity, whether by contract or otherwise, or (ii) ownership of fifty percent (50%) or more
of the outstanding shares, or (iii) beneficial ownership of such entity. "You" (or "Your") shall mean an
individual or Legal Entity exercising permissions granted by this License. "Source" form shall mean the

Object form, made available under the License, as indicated by a copyright notice that is included in or
attached to the work (an example is provided in the Appendix below). "Derivative Works" shall mean any
work, whether in Source or Object form, that is based on (or derived from) the Work and for which the
editorial revisions, annotations, elaborations, or other modifications represent, as a whole, an original work
of authorship. For the purposes of this License, Derivative Works shall not include works that remain
separable from, or merely link (or bind by name) to the interfaces of, the Work and Derivative Works thereof.
"Contribution" shall mean any work of authorship, including the original version of the Work and any
modifications or additions to that Work or Derivative Works thereof, that is intentionally submitted to Licensor
for inclusion in the Work by the copyright owner or by an individual or Legal Entity authorized to submit on
behalf of the copyright owner. For the purposes of this definition, "submitted" means any form of electronic,
verbal, or written communication sent to the Licensor or its representatives, including but not limited to

contents of the NOTICE file are for informational purposes only and do not modify the License. You
may add Your own attribution notices within Derivative Works that You distribute, alongside or as an
addendum to the NOTICE text from the Work, provided that such additional attribution notices cannot
be construed as modifying the License.
You may add Your own copyright statement to Your modifications and may provide additional or
different license terms and conditions for use, reproduction, or distribution of Your modifications, or for
any such Derivative Works as a whole, provided Your use, reproduction, and distribution of the Work
otherwise complies with the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise, any Contribution intentionally submitted
for inclusion in the Work by You to the Licensor shall be under the terms and conditions of this License,
without any additional terms or conditions. Notwithstanding the above, nothing herein shall supersede or
modify the terms of any separate license agreement you may have executed with Licensor regarding such
Contributions.

in writing, shall any Contributor be liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a result of this License or out of the use or
inability to use the Work (including but not limited to damages for loss of goodwill, work stoppage, computer
failure or malfunction, or any and all other commercial damages or losses), even if such Contributor has
been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing the Work or Derivative Works thereof, You
may choose to offer, and charge a fee for, acceptance of support, warranty, indemnity, or other liability
obligations and/or rights consistent with this License. However, in accepting such obligations, You may act
only on Your own behalf and on Your sole responsibility, not on behalf of any other Contributor, and only if
You agree to indemnify, defend, and hold each Contributor harmless for any liability incurred by, or claims

with the License. You may obtain a copy of the License at http://www.apache.org/licenses/LICENSE-2.0

Polycom CMA Desktop Help Book
Unless required by applicable law or agreed to in writing, software distributed under the License is distributed on
an "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. See the
License for the specific language governing permissions and limitations under the License.
• 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.
• 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.
• 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 ection 6. Any executables containing that work also fall under Section 6, whether or not
they are linked directly with the Library itself.
• 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:
1. 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.)
2. 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.
3. 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.
38
Copyrights and Legal Notices
4. 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.
5. 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.
• 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:
1. 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.
2. 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.
• 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.
• 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.
• 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.
• 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.
• 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.

• 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.
• 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.
• Submission of Contributions. Unless You explicitly state otherwise, any Contribution intentionally submitted for
inclusion in the Work by You to the Licensor shall be under the terms and conditions of this License, without any
additional terms or conditions. Notwithstanding the above, nothing herein shall supersede or modify the terms of
any separate license agreement you may have executed with Licensor regarding such Contributions.
• Trademarks. This License does not grant permission to use the trade names, trademarks, service marks, or
product names of the Licensor, except as required for reasonable and customary use in describing the origin of the
Work and reproducing the content of the NOTICE file.

(and each Contributor provides its Contributions) on an "AS IS" BASIS, WITHOUT WARRANTIES OR

solely responsible for determining the appropriateness of using or redistributing the Work and assume any risks
associated with Your exercise of permissions under this License.
• Limitation of Liability. In no event and under no legal theory, whether in tort (including negligence), contract, or
otherwise, unless required by applicable law (such as deliberate and grossly negligent acts) or agreed to in writing,
shall any Contributor be liable to You for damages, including any direct, indirect, special, incidental, or
consequential damages of any character arising as a result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill, work stoppage, computer failure or malfunction, or
any and all other commercial damages or losses), even if such Contributor has been advised of the possibility of
such damages.
• Accepting Warranty or Additional Liability. While redistributing the Work or Derivative Works thereof, You may
choose to offer, and charge a fee for, acceptance of support, warranty, indemnity, or other liability obligations
and/or rights consistent with this License. However, in accepting such obligations, You may act only on Your own
behalf and on Your sole responsibility, not on behalf of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability incurred by, or claims asserted against, such
Contributor by reason of your accepting any such warranty or additional liability.
• You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given

they are linked directly with the Library itself.
• 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:
1. 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.)
2. 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.
3. 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.
4. 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.
5. 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.
• 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:
1. 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.
41

2. 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.
• 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.
• 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.
•
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.
• 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.
• 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.
• 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.
• 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.
