Please read at least the files install.txt and usage.txt. Some
information can also be found in the JPEG FAQ (Frequently Asked
Questions) article. See ARCHIVE LOCATIONS below to find out
where to obtain the FAQ article.
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.
