Epson Projector L1500U User Manual

							301
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 
						

							302
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.

Copyright (C)  
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:

Yoyodyne, Inc., hereby disclaims all copyright interest in the library `Frob (a library for tweaking knobs)

conditions provided by owner of the copyright to the libjpeg.

MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.

License terms of conditions of each program which are provided by owner of the copyright to the
libjpeg are as follows.
Copyright (C) 1994-1997, Thomas G. Lane. This file is part of the Independent JPEG Groups software.
For conditions of distribution and use, see the accompanying README file.
This distribution contains the sixth public release of the Independent JPEG Groups free JPEG software.
You are welcome to redistribute this software and to use it for any purpose, subject to the conditions
under LEGAL ISSUES, below.
LEGAL ISSUES
============
In plain English:
1. We dont 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 dont 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 youve 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 fitness for a particular purpose. This software is
provided AS IS, and you, its user, assume the entire risk as to its quality and accuracy. 
						

							304
This software is copyright (C) 1991-1998, Thomas G. Lane. All Rights Reserved except as specified
below.
Permission is hereby granted to use, copy, modify, and distribute this software (or portions thereof) for
any purpose, without fee, subject to these conditions:
(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 acknowledge us.
Permission is NOT granted for the use of any IJG authors name or company name in advertising or
publicity relating to this software or products derived from it. This software may be referred to only as
the Independent JPEG Groups software.
We specifically permit and encourage the use of this software as the basis of commercial products,
provided that all warranty or liability claims are assumed by the product vendor.
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, ltconfig, ltmain.sh). Another support script, install-sh, is copyright by M.I.T. but is also freely
distributable.
It appears that the arithmetic coding option of the JPEG spec is covered by patents owned by IBM,
AT&T, and Mitsubishi. Hence arithmetic coding cannot legally be used without obtaining one or more
licenses. For this reason, support for arithmetic coding has been removed from the free JPEG software.
(Since arithmetic coding provides only a marginal gain over the unpatented Huffman mode, it is unlikely
that very many implementations will support it.) So far as we are aware, there are no patent restrictions
on the remaining code.
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 
						

							305
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.
