| 
 | ||
| 	If you want to understand how the JPEG code works, we suggest reading one or

| 	more of the REFERENCES, then 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 compression and
 | ||
| 	decompression.  JPEG (pronounced "jay-peg") is a standardized compression
 | ||
| 	method for full-color and gray-scale images.  JPEG is intended for compressing
 | ||
| 	"real-world" scenes; line drawings, cartoons and other non-realistic images
 | ||
| 	are not its strong suit.  JPEG is lossy, meaning that the output image is not
 | ||
| 	exactly identical to the input image.  Hence you must not use JPEG if you
 | ||
| 	have to have identical output bits.  However, on typical photographic images,
 | ||
| 	very good compression levels can be obtained with no visible change, and
 | ||
| 	remarkably high compression levels are possible if you can tolerate a
 | ||
| 	low-quality image.  For more details, see the references, or just experiment
 | ||
| 	with various compression settings.
 | ||
| 
 | ||
| 	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.
 | ||
| 	For legal reasons, we are not distributing code for the arithmetic-coding
 | ||
| 	variants of JPEG; see LEGAL ISSUES.  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.
 | ||
| 
 | ||
| 	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) 1991-1998, 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 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,
 | ||
| 	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 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 highly 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 ftp://ftp.uu.net/graphics/jpeg/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...
 | ||
| 
 | ||
| 	The best full 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).  This is by far the most complete exposition of JPEG
 | ||
| 	in existence, and we highly recommend it.
 | ||
| 
 | ||
| 	The JPEG standard itself is not available electronically; you must order a
 | ||
| 	paper copy through ISO or ITU.  (Unless you feel a need to own a certified
 | ||
| 	official copy, we recommend buying the Pennebaker and Mitchell book instead;
 | ||
| 	it's much cheaper and includes a great deal of useful explanatory material.)
 | ||
| 	In the USA, copies of the standard may be ordered from ANSI Sales at (212)
 | ||
| 	642-4900, or from Global Engineering Documents at (800) 854-7179.  (ANSI
 | ||
| 	doesn't take credit card orders, but Global does.)  It's not cheap: as of
 | ||
| 	1992, ANSI was charging $95 for Part 1 and $47 for Part 2, plus 7%
 | ||
| 	shipping/handling.  The 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.
 | ||
| 
 | ||
| 	Some extensions to the original JPEG standard are defined in JPEG Part 3,
 | ||
| 	a newer ISO standard numbered ISO/IEC IS 10918-3 and ITU-T T.84.  IJG
 | ||
| 	currently does not support any Part 3 extensions.
 | ||
| 
 | ||
| 	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.  A copy of the JFIF spec is available from:
 | ||

| 	A PostScript version of this document is available by FTP at
 | ||
| 	ftp://ftp.uu.net/graphics/jpeg/jfif.ps.gz.  There is also a plain text
 | ||
| 	version at ftp://ftp.uu.net/graphics/jpeg/jfif.txt.gz, but it is missing
 | ||
| 	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 ftp.sgi.com or
 | ||
| 	from ftp://ftp.uu.net/graphics/jpeg/.  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.  libtiff is available
 | ||
| 	from ftp://ftp.sgi.com/graphics/tiff/.

| 	RELATED SOFTWARE
 | ||
| 	================
 | ||
| 
 | ||
| 	Numerous viewing and image manipulation programs now support JPEG.  (Quite a
 | ||
| 	few of them use this library to do so.)  The JPEG FAQ described above lists
 | ||
| 	some of the more popular free and shareware viewers, and tells where to
 | ||
| 	obtain them on Internet.
 | ||
| 
 | ||
| 	If you are on a Unix machine, we highly recommend Jef Poskanzer's free
 | ||
| 	PBMPLUS software, which provides many useful operations on PPM-format image
 | ||
| 	files.  In particular, it can convert PPM images to and from a wide range of
 | ||
| 	other formats, thus making cjpeg/djpeg considerably more useful.  The latest
 | ||
| 	version is distributed by the NetPBM group, and is available from numerous
 | ||
| 	sites, notably ftp://wuarchive.wustl.edu/graphics/graphics/packages/NetPBM/.
 | ||
| 	Unfortunately PBMPLUS/NETPBM is not nearly as portable as the IJG software is;
 | ||
| 	you are likely to have difficulty making it work on any non-Unix machine.
 | ||
| 
 | ||
| 	A different free JPEG implementation, written by the PVRG group at Stanford,
 | ||
| 	is available from ftp://havefun.stanford.edu/pub/jpeg/.  This program
 | ||
| 	is designed for research and experimentation rather than production use;
 | ||
| 	it is slower, harder to use, and less portable than the IJG code, but it
 | ||
| 	is easier to read and modify.  Also, the PVRG code supports lossless JPEG,
 | ||
| 	which we do not.  (On the other hand, it doesn't do progressive JPEG.)
 | ||
| 
 | ||
| 
 | ||
| 	FILE FORMAT WARS
 | ||
| 	================
 | ||
| 
 | ||
| 	Some JPEG programs produce files that are not compatible with our library.
 | ||
| 	The root of the problem is that the ISO JPEG committee failed to specify a
 | ||
| 	concrete file format.  Some vendors "filled in the blanks" on their own,
 | ||
| 	creating proprietary formats that no one else could read.  (For example, none
 | ||
| 	of the early commercial JPEG implementations for the Macintosh were able to
 | ||
| 	exchange compressed files.)
 | ||
| 
 | ||
| 	The file format we have adopted is called JFIF (see REFERENCES).  This format
 | ||
| 	has been agreed to by a number of major commercial JPEG vendors, and it has
 | ||
| 	become the de facto standard.  JFIF is a minimal or "low end" representation.
 | ||
| 	We recommend the use of TIFF/JPEG (TIFF revision 6.0 as modified by TIFF
 | ||
| 	Technical Note #2) for "high end" applications that need to record a lot of
 | ||
| 	additional data about an image.  TIFF/JPEG is fairly new and not yet widely
 | ||
| 	supported, unfortunately.
 | ||
| 
 | ||
| 	The upcoming JPEG Part 3 standard defines a file format called SPIFF.
 | ||
| 	SPIFF is interoperable with JFIF, in the sense that most JFIF decoders should
 | ||
| 	be able to read the most common variant of SPIFF.  SPIFF has some technical
 | ||
| 	advantages over JFIF, but its major claim to fame is simply that it is an
 | ||
| 	official standard rather than an informal one.  At this point it is unclear
 | ||
| 	whether SPIFF will supersede JFIF or whether JFIF will remain the de-facto
 | ||
| 	standard.  IJG intends to support SPIFF once the standard is frozen, but we
 | ||
| 	have not decided whether it should become our default output format or not.
 | ||
| 	(In any case, our decoder will remain capable of reading JFIF indefinitely.)
 | ||
| 
 | ||
| 	Various proprietary file formats incorporating JPEG compression also exist.
 | ||
| 	We have little or no sympathy for the existence of these formats.  Indeed,
 | ||
| 	one of the original reasons for developing this free software was to help
 | ||
| 	force convergence on common, open format standards for JPEG files.  Don't
 | ||
| 	use a proprietary file format!
 | ||
| 
 | ||
| 
 | ||
| 	TO DO
 | ||
| 	=====
 | ||
| 
 | ||
| 	The major thrust for v7 will probably be improvement of visual quality.
 | ||
| 	The current method for scaling the quantization tables is known not to be
 | ||
| 	very good at low Q values.  We also intend to investigate block boundary
 | ||
| 	smoothing, "poor man's variable quantization", and other means of improving
 | ||
| 	quality-vs-file-size performance without sacrificing compatibility.
 | ||
| 
 | ||
| 	In future versions, we are considering supporting some of the upcoming JPEG
 | ||
| 	Part 3 extensions --- principally, variable quantization and the SPIFF file
 | ||
| 	format.
 | ||
| 
 | ||
| 	As always, speeding things up is of great interest.
 | ||
| 
 | ||
| 	Please send bug reports, offers of help, etc. to jpeg-info@uunet.uu.net.
