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.

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:
