Before Using the Machine
1
package is highly portable C code; we have tested it on many machines ranging from PCs to
Crays.
We are releasing this software for both noncommercial and commercial use. Companies are
welcome to use it as the basis for JPEG-related products. We do not ask a royalty, although
we do ask for an acknowledgement in product literature (see the README file in the
distribution for details). We hope to make this software industrial-quality --- although, as
with anything that's free, we offer no warranty and accept no liability. For more
information, contact jpeg-info@jpegclub.org.

jpegsrc.vN.tar.gz contains source code, documentation, and test files for release N in Unix
format. jpegsrN.zip contains source code, documentation, and test files for release N in
Windows format. jpegaltui.vN.tar.gz contains source code for an alternate user interface for
cjpeg/djpeg in Unix format. jpegaltuiN.zip contains source code for an alternate user
interface for cjpeg/djpeg in Windows format. wallace.ps.gz is a PostScript file of Greg
Wallace's introductory article about JPEG. This is an update of the article that appeared in
