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
