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.
|
||||
|
||||
NO WARRANTY
|
||||
|
||||
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
|
||||
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
|
||||
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
|
||||
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
|
||||
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
|
||||
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
|
||||
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
|
||||
LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
|
||||
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
|
||||
|
||||
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
|
||||
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
|
||||
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
|
||||
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
|
||||
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
|
||||
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
|
||||
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
|
||||
DAMAGES.
|
||||
|
||||
END OF TERMS AND CONDITIONS
|
||||
|
||||
How to Apply These Terms to Your New Libraries
|
||||
|
||||
If you develop a new library, and you want it to be of the greatest
|
||||
possible use to the public, we recommend making it free software that
|
||||
everyone can redistribute and change. You can do so by permitting
|
||||
redistribution under these terms (or, alternatively, under the terms of the
|
||||
ordinary General Public License).
|
||||
|
||||
To apply these terms, attach the following notices to the library. It is
|
||||
safest to attach them to the start of each source file to most effectively
|
||||
convey the exclusion of warranty; and each file should have at least the
|
||||
"copyright" line and a pointer to where the full notice is found.
|
||||
|
||||
<one line to give the library's name and a brief idea of what it does.>
|
||||
Copyright (C) <year> <name of author>
|
||||
|
||||
This library is free software; you can redistribute it and/or
|
||||
modify it under the terms of the GNU Lesser General Public
|
||||
License as published by the Free Software Foundation; either
|
||||
version 2.1 of the License, or (at your option) any later version.
|
||||
|
||||
This library is distributed in the hope that it will be useful,
|
||||
but WITHOUT ANY WARRANTY; without even the implied warranty of
|
||||
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
|
||||
Lesser General Public License for more details.
|
||||
|
||||
You should have received a copy of the GNU Lesser General Public
|
||||
License along with this library; if not, write to the Free Software
|
||||
Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
|
||||
|
||||
Also add information on how to contact you by electronic and paper mail.
|
||||
|
||||
You should also get your employer (if you work as a programmer) or your
|
||||
school, if any, to sign a "copyright disclaimer" for the library, if
|
||||
necessary. Here is a sample; alter the names:
|
||||

* On Linux and other Unix flavors OpenCV uses default or user-built ffmpeg/libav libraries.
|
||||
If user builds ffmpeg/libav from source and wants OpenCV to stay BSD library, not GPL/LGPL,
|
||||
he/she should use --enabled-shared configure flag and make sure that no GPL components are
|
||||
enabled (some notable examples are x264 (H264 encoder) and libac3 (Dolby AC3 audio codec)).
|
||||
See https://www.ffmpeg.org/legal.html for details.
|
||||
The build script is to be fixed.
|
||||
Right now it assumes that 32-bit MinGW is in the system path and
|
||||
64-bit mingw is installed to c:\Apps\MinGW64.
|
||||
|
||||
If you want to play very safe and do not want to use FFMPEG at all, regardless of whether it's installed on
|
||||
your system or not, configure and build OpenCV using CMake with WITH_FFMPEG=OFF flag. OpenCV will then use
|
||||
AVFoundation (OSX), GStreamer (Linux) or other available backends supported by opencv_videoio module.
|
||||
It is important that gcc is used, not g++!
|
||||
Otherwise the produced DLL will likely be dependent on libgcc_s_dw2-1.dll or similar DLL.
|
||||
While we want to make the DLLs with minimum dependencies: Win32 libraries + msvcrt.dll.
|
||||
|
||||
There is also our self-contained motion jpeg codec, which you can use without any worries.
|
||||
It handles CV_FOURCC('M', 'J', 'P', 'G') streams within an AVI container (".avi").
|
||||
ffopencv.c is really a C++ source, hence -x c++ is used.
|
||||
|
||||
* On Windows OpenCV uses pre-built ffmpeg binaries, built with proper flags (without GPL components) and
|
||||
wrapped with simple, stable OpenCV-compatible API.
|
||||
The binaries are opencv_ffmpeg.dll (version for 32-bit Windows) and
|
||||
opencv_ffmpeg_64.dll (version for 64-bit Windows).
|
||||
How to update opencv_ffmpeg.dll and opencv_ffmpeg_64.dll when a new version of FFMPEG is release?
|
||||
|
||||
See build_win32.txt for the build instructions, if you want to rebuild opencv_ffmpeg*.dll from scratch.
|
||||
1. Install 32-bit MinGW + MSYS from
|
||||
http://sourceforge.net/projects/mingw/files/Automated%20MinGW%20Installer/mingw-get-inst/
|
||||
Let's assume, it's installed in C:\MSYS32.
|
||||
2. Install 64-bit MinGW. http://mingw-w64.sourceforge.net/
|
||||
Let's assume, it's installed in C:\MSYS64
|
||||
3. Copy C:\MSYS32\msys to C:\MSYS64\msys. Edit C:\MSYS64\msys\etc\fstab, change C:\MSYS32 to C:\MSYS64.
|
||||
|
||||
4. Now you have working MSYS32 and MSYS64 environments.
|
||||
Launch, one by one, C:\MSYS32\msys\msys.bat and C:\MSYS64\msys\msys.bat to create your home directories.
|
||||
|
||||
The pre-built opencv_ffmpeg*.dll is:
|
||||
* LGPL library, not BSD libraries.
|
||||
* Loaded at runtime by opencv_videoio module.
|
||||
If it succeeds, ffmpeg can be used to decode/encode videos;
|
||||
otherwise, other API is used.
|
||||
4. Download ffmpeg-x.y.z.tar.gz (where x.y.z denotes the actual ffmpeg version).
|
||||
Copy it to C:\MSYS{32|64}\msys\home\<loginname> directory.
|
||||
|
||||
FFMPEG build contains H264 encoder based on the OpenH264 library, that should be installed separatelly.
|
||||
OpenH264 Video Codec provided by Cisco Systems, Inc.
|
||||
See https://github.com/cisco/openh264/releases for details and OpenH264 license.
|
||||
Downloaded binary file can be placed into global system path (System32 or SysWOW64) or near application binaries.
|
||||
You can also specify location of binary file via OPENH264_LIBRARY_PATH environment variable.
|
||||
5. To build 32-bit ffmpeg libraries, run C:\MSYS32\msys\msys.bat and type the following commands:
|
||||
|
||||
5.1. tar -xzf ffmpeg-x.y.z.tar.gz
|
||||
5.2. mkdir build
|
||||
5.3. cd build
|
||||
5.4. ../ffmpeg-x.y.z/configure --enable-w32threads
|
||||
5.5. make
|
||||
5.6. make install
|
||||
5.7. cd /local/lib
|
||||
5.8. strip -g *.a
|
||||
|
||||
6. Then repeat the same for 64-bit case. The output libs: libavcodec.a etc. need to be renamed to libavcodec64.a etc.
|
||||
|
||||
7. Then, copy all those libs to <opencv>\3rdparty\lib\, copy the headers to <opencv>\3rdparty\include\ffmpeg_.
|
||||
|
||||
8. Then, go to <opencv>\3rdparty\ffmpeg, edit make.bat
|
||||
(change paths to the actual paths to your msys32 and msys64 distributions) and then run make.bat
|
||||
|
||||
If LGPL/GPL software can not be supplied with your OpenCV-based product, simply exclude
|
||||
opencv_ffmpeg*.dll from your distribution; OpenCV will stay fully functional except for the ability to
|
||||
decode/encode videos using FFMPEG (though, it may still be able to do that using other API,
|
||||
such as Video for Windows, Windows Media Foundation or our self-contained motion jpeg codec).
|
||||
|
||||
See license.txt for the FFMPEG copyright notice and the licensing terms.

|
||||
* @{
|
||||
* AVOptions provide a generic system to declare options on arbitrary structs
|
||||
* ("objects"). An option can have a help text, a type and a range of possible
|
||||
* values. Options may then be enumerated, read and written to.
|
||||
*
|
||||
* @section avoptions_implement Implementing AVOptions
|
||||
* This section describes how to add AVOptions capabilities to a struct.
|
||||
*
|
||||
* All AVOptions-related information is stored in an AVClass. Therefore
|
||||
* the first member of the struct must be a pointer to an AVClass describing it.
|
||||
* The option field of the AVClass must be set to a NULL-terminated static array
|
||||
* of AVOptions. Each AVOption must have a non-empty name, a type, a default
|
||||
* value and for number-type AVOptions also a range of allowed values. It must
|
||||
* also declare an offset in bytes from the start of the struct, where the field
|
||||
* associated with this AVOption is located. Other fields in the AVOption struct
|
||||
* should also be set when applicable, but are not required.
|
||||
*
|
||||
* The following example illustrates an AVOptions-enabled struct:
|
||||
* @code
|
||||
* typedef struct test_struct {
|
||||
* AVClass *class;
|
||||
* int int_opt;
|
||||
* char *str_opt;
|
||||
* uint8_t *bin_opt;
|
||||
* int bin_len;
|
||||
* } test_struct;
|
||||
*
|
||||
* static const AVOption options[] = {
|
||||
* { "test_int", "This is a test option of int type.", offsetof(test_struct, int_opt),
|
||||
* AV_OPT_TYPE_INT, { -1 }, INT_MIN, INT_MAX },
|
||||
* { "test_str", "This is a test option of string type.", offsetof(test_struct, str_opt),
|
||||
* AV_OPT_TYPE_STRING },
|
||||
* { "test_bin", "This is a test option of binary type.", offsetof(test_struct, bin_opt),
|
||||
* AV_OPT_TYPE_BINARY },
|
||||
* { NULL },
|
||||
* };
|
||||
*
|
||||
* static const AVClass test_class = {
|
||||
* .class_name = "test class",
|
||||
* .item_name = av_default_item_name,
|
||||
* .option = options,
|
||||
* .version = LIBAVUTIL_VERSION_INT,
|
||||
* };
|
||||
* @endcode
|
||||
*
|
||||
* Next, when allocating your struct, you must ensure that the AVClass pointer
|
||||
* is set to the correct value. Then, av_opt_set_defaults() must be called to
|
||||
* initialize defaults. After that the struct is ready to be used with the
|
||||
* AVOptions API.
|
||||
*
|
||||
* When cleaning up, you may use the av_opt_free() function to automatically
|
||||
* free all the allocated string and binary options.
|
||||
*
|
||||
* Continuing with the above example:
|
||||
*
|
||||
* @code
|
||||
* test_struct *alloc_test_struct(void)
|
||||
* {
|
||||
* test_struct *ret = av_malloc(sizeof(*ret));
|
||||
* ret->class = &test_class;
|
||||
* av_opt_set_defaults(ret);
|
||||
* return ret;
|
||||
* }
|
||||
* void free_test_struct(test_struct **foo)
|
||||
* {
|
||||
* av_opt_free(*foo);
|
||||
* av_freep(foo);
|
||||
* }
|
||||
* @endcode
|
||||
*
|
||||
* @subsection avoptions_implement_nesting Nesting
|
||||
* It may happen that an AVOptions-enabled struct contains another
|
||||
* AVOptions-enabled struct as a member (e.g. AVCodecContext in
|
||||
* libavcodec exports generic options, while its priv_data field exports
|
||||
* codec-specific options). In such a case, it is possible to set up the
|
||||
* parent struct to export a child's options. To do that, simply
|
||||
* implement AVClass.child_next() and AVClass.child_class_next() in the
|
||||
* parent struct's AVClass.
|
||||
* Assuming that the test_struct from above now also contains a
|
||||
* child_struct field:
|
||||
*
|
||||
* @code
|
||||
* typedef struct child_struct {
|
||||
* AVClass *class;
|
||||
* int flags_opt;
|
||||
* } child_struct;
|
||||
* static const AVOption child_opts[] = {
|
||||
* { "test_flags", "This is a test option of flags type.",
|
||||
* offsetof(child_struct, flags_opt), AV_OPT_TYPE_FLAGS, { 0 }, INT_MIN, INT_MAX },
|
||||
* { NULL },
|
||||
* };
|
||||
* static const AVClass child_class = {
|
||||
* .class_name = "child class",
|
||||
* .item_name = av_default_item_name,
|
||||
* .option = child_opts,
|
||||
* .version = LIBAVUTIL_VERSION_INT,
|
||||
* };
|
||||
*
|
||||
* void *child_next(void *obj, void *prev)
|
||||
* {
|
||||
* test_struct *t = obj;
|
||||
* if (!prev && t->child_struct)
|
||||
* return t->child_struct;
|
||||
* return NULL
|
||||
* }
|
||||
* const AVClass child_class_next(const AVClass *prev)
|
||||
* {
|
||||
* return prev ? NULL : &child_class;
|
||||
* }
|
||||
* @endcode
|
||||
* Putting child_next() and child_class_next() as defined above into
|
||||
* test_class will now make child_struct's options accessible through
|
||||
* test_struct (again, proper setup as described above needs to be done on
|
||||
* child_struct right after it is created).
|
||||
*
|
||||
* From the above example it might not be clear why both child_next()
|
||||
* and child_class_next() are needed. The distinction is that child_next()
|
||||
* iterates over actually existing objects, while child_class_next()
|
||||
* iterates over all possible child classes. E.g. if an AVCodecContext
|
||||
* was initialized to use a codec which has private options, then its
|
||||
* child_next() will return AVCodecContext.priv_data and finish
|
||||
* iterating. OTOH child_class_next() on AVCodecContext.av_class will
|
||||
* iterate over all available codecs with private options.
|
||||
*
|
||||
* @subsection avoptions_implement_named_constants Named constants
|
||||
* It is possible to create named constants for options. Simply set the unit
|
||||
* field of the option the constants should apply to to a string and
|
||||
* create the constants themselves as options of type AV_OPT_TYPE_CONST
|
||||
* with their unit field set to the same string.
|
||||
* Their default_val field should contain the value of the named
|
||||
* constant.
|
||||
* For example, to add some named constants for the test_flags option
|
||||
* above, put the following into the child_opts array:
|
||||
* @code
|
||||
* { "test_flags", "This is a test option of flags type.",
|
||||
* offsetof(child_struct, flags_opt), AV_OPT_TYPE_FLAGS, { 0 }, INT_MIN, INT_MAX, "test_unit" },
|
||||
* { "flag1", "This is a flag with value 16", 0, AV_OPT_TYPE_CONST, { 16 }, 0, 0, "test_unit" },
|
||||
* @endcode
|
||||
*
|
||||
* @section avoptions_use Using AVOptions
|
||||
* This section deals with accessing options in an AVOptions-enabled struct.
|
||||
* Such structs in FFmpeg are e.g. AVCodecContext in libavcodec or
|
||||
* AVFormatContext in libavformat.
|
||||
*
|
||||
* @subsection avoptions_use_examine Examining AVOptions
|
||||
* The basic functions for examining options are av_opt_next(), which iterates
|
||||
* over all options defined for one object, and av_opt_find(), which searches
|
||||
* for an option with the given name.
|
||||
*
|
||||
* The situation is more complicated with nesting. An AVOptions-enabled struct
|
||||
* may have AVOptions-enabled children. Passing the AV_OPT_SEARCH_CHILDREN flag
|
||||
* to av_opt_find() will make the function search children recursively.
|
||||
*
|
||||
* For enumerating there are basically two cases. The first is when you want to
|
||||
* get all options that may potentially exist on the struct and its children
|
||||
* (e.g. when constructing documentation). In that case you should call
|
||||
* av_opt_child_class_next() recursively on the parent struct's AVClass. The
|
||||
* second case is when you have an already initialized struct with all its
|
||||
* children and you want to get all options that can be actually written or read
|
||||
* from it. In that case you should call av_opt_child_next() recursively (and
|
||||
* av_opt_next() on each result).
|
||||
*
|
||||
* @subsection avoptions_use_get_set Reading and writing AVOptions
|
||||
* When setting options, you often have a string read directly from the
|
||||
* user. In such a case, simply passing it to av_opt_set() is enough. For
|
||||
* non-string type options, av_opt_set() will parse the string according to the
|
||||
* option type.
|
||||
*
|
||||
* Similarly av_opt_get() will read any option type and convert it to a string
|
||||
* which will be returned. Do not forget that the string is allocated, so you
|
||||
* have to free it with av_free().
|
||||
*
|
||||
* In some cases it may be more convenient to put all options into an
|
||||
* AVDictionary and call av_opt_set_dict() on it. A specific case of this
|
||||
* are the format/codec open functions in lavf/lavc which take a dictionary
|
||||
* filled with option as a parameter. This allows to set some options
|
||||
* that cannot be set otherwise, since e.g. the input file format is not known
|
||||
* before the file is actually opened.

|

* PIX_FMT_RGB32 is handled in an endian-specific manner. An RGBA
|
||||
* color is put together as:
|
||||
* (A << 24) | (R << 16) | (G << 8) | B
|
||||
* This is stored as BGRA on little-endian CPU architectures and ARGB on
|
||||
* big-endian CPUs.
|
||||
*
|
||||
* @par
|
||||
* When the pixel format is palettized RGB (PIX_FMT_PAL8), the palettized
|
||||
* image data is stored in AVFrame.data[0]. The palette is transported in
|
||||
* AVFrame.data[1], is 1024 bytes long (256 4-byte entries) and is
|
||||
* formatted the same as in PIX_FMT_RGB32 described above (i.e., it is
|
||||
* also endian-specific). Note also that the individual RGB palette
|
||||
* components stored in AVFrame.data[1] should be in the range 0..255.
|
||||
* This is important as many custom PAL8 video codecs that were designed
|
||||
* to run on the IBM VGA graphics adapter use 6-bit palette components.
|
||||
*
|
||||
* @par
|
||||
* For all the 8bit per pixel formats, an RGB32 palette is in data[1] like
|
||||
* for pal8. This palette is filled in automatically by the function
|
||||
* allocating the picture.
|
||||
*
|
||||
* @note
|
||||
* make sure that all newly added big endian formats have pix_fmt&1==1
|
||||
* and that all newly added little endian formats have pix_fmt&1==0
|
||||
* this allows simpler detection of big vs little endian.

Django inspired non-XML syntax but supports inline expressions and

an optional sandboxed environment.

.. class:: MinimalClientInterface

.. method:: set(key, value[, timeout])

Stores the bytecode in the cache. `value` is a string and

`timeout` the timeout of the key. If timeout is not provided

a default timeout or no timeout should be assumed, if it's
|
||||
provided it's an integer with the number of seconds the cache
|
||||
item should exist.

.. method:: get(key)

Returns the value for the cache key. If the item does not

The other arguments to the constructor are the prefix for all keys that

this is that an extension can be bound to another environment (for

As extensions are created by the environment they cannot accept any

a factory function, but that is not possible as extensions are identified

by their import name. The correct way to configure the extension is
|

storing the configuration values on the environment. Because this way the

environment ends up acting as central configuration storage the
|

attributes may clash which is why extensions have to ensure that the names
|

they choose for configuration are not too generic. ``prefix`` for example

is a terrible name, ``fragment_cache_prefix`` on the other hand is a good

default this function returns matches in babel style that means non string

parameters as well as keyword arguments are returned as `None`. This
|
||||
allows Babel to figure out what you really meant if you are using
|
||||
gettext functions that allow keyword arguments for placeholder expansion.
|
||||
If you don't want that behavior set the `babel_style` parameter to `False`
|
||||
which causes only strings to be returned and parameters are always stored
|
||||
in tuples. As a consequence invalid gettext calls (calls without a single
|
||||
string parameter or string parameters after non-string parameters) are
|
||||
skipped.
|
||||
|
||||
This example explains the behavior:
|
||||
|
||||
>>> from jinja2 import Environment
|
||||
>>> env = Environment()
|
||||
>>> node = env.parse('{{ (_("foo"), _(), ngettext("foo", "bar", 42)) }}')
|
||||
>>> list(extract_from_ast(node))
|
||||
[(1, '_', 'foo'), (1, '_', ()), (1, 'ngettext', ('foo', 'bar', None))]
|

>>> list(extract_from_ast(node, babel_style=False))
|
||||
[(1, '_', ('foo',)), (1, 'ngettext', ('foo', 'bar'))]
|
||||
|
||||
For every string found this function yields a ``(lineno, function,
|
||||
message)`` tuple, where:
|
||||
|
||||
* ``lineno`` is the number of the line on which the string was found,
|
||||
* ``function`` is the name of the ``gettext`` function used (if the
|
||||
string was extracted from embedded Python code), and
|
||||
* ``message`` is the string itself (a ``unicode`` object, or a tuple
|
||||
of ``unicode`` objects for functions with multiple string arguments).
|
||||
|
||||
This extraction function operates on the AST and is because of that unable
|
||||
to extract any comments. For comment support you have to use the babel
|
||||
extraction interface or extract comments yourself.

This module implements a Jinja / Python combination lexer. The

`Lexer` class provided by this module is used to do some preprocessing
|

for Jinja.
|

|
||||
On the one hand it filters out invalid operators like the bitshift
|
||||
operators we don't allow in templates. On the other hand it separates
|
||||
template code and python code in expressions.

needing to be escaped. This implements the `__html__` interface a couple

||||
of frameworks and web applications use. :class:`Markup` is a direct
|
||||
subclass of `unicode` and provides all the methods of `unicode` just that
|
||||
it escapes arguments passed and always returns `Markup`.
|
||||
|
||||
The `escape` function returns markup objects so that double escaping can't
|
||||
happen.
|
||||
|
||||
The constructor of the :class:`Markup` class can be used for three
|
||||
different things: When passed an unicode object it's assumed to be safe,
|
||||
when passed an object with an HTML representation (has an `__html__`
|
||||
method) that representation is used, otherwise the object passed is
|
||||
converted into a unicode string and then assumed to be safe:
|
||||
|
||||
>>> Markup("Hello <em>World</em>!")
|
||||
Markup(u'Hello <em>World</em>!')
|
||||
>>> class Foo(object):
|
||||
... def __html__(self):
|
||||
... return '<a href="#">foo</a>'
|
||||
...
|
||||
>>> Markup(Foo())
|
||||
Markup(u'<a href="#">foo</a>')
|
||||
|
||||
If you want object passed being always treated as unsafe you can use the
|
||||
:meth:`escape` classmethod to create a :class:`Markup` object:
|
||||
|
||||
>>> Markup.escape("Hello <em>World</em>!")
|
||||
Markup(u'Hello <em>World</em>!')
|
||||
|
||||
Operations on a markup string are markup aware which means that all
|
||||
arguments are passed through the :func:`escape` function:
|
||||
|
||||
>>> em = Markup("<em>%s</em>")
|
||||
>>> em % "foo & bar"
|

Markup(u'<em>foo & bar</em>')
