libjpeg-8.dll

	jpeg-8c
	http://www.ijg.org/
	
	This software is the work of Tom Lane, Guido Vollbeding, Philip Gladstone,
	Bill Allombert, Jim Boucher, Lee Crocker, Bob Friesenhahn, Ben Jackson,
	Julian Minguillon, Luis Ortiz, George Phillips, Davide Rossi, Ge' Weijers,
	and other members of the Independent JPEG Group.

	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.

	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.

	This software is copyright (C) 1991-2011, Thomas G. Lane, Guido Vollbeding.
	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 author's 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 Group's
	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,
	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."
