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 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.

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.

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

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.”

innards of the JPEG software.
