operation manual

standardized compression method for full-color and gray-
scale images.
The distributed programs provide conversion between
JPEG "JFIF" format and image files in PBMPLUS
PPM/PGM, GIF, BMP, and Targa file formats. The core
compression and decompression library can easily be
reused in other programs, such as image viewers. The
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-
[e-mail].

introductory article about JPEG. This is an update of the
article that appeared in the April 1991 Communications of
the ACM.
jpeg.documents.gz tells where to obtain the JPEG
standard and documents about JPEG-related file
formats.
jfif.ps.gz is a PostScript file of the JFIF (JPEG File
Interchange Format) format specification.
jfif.txt.gz is a plain text transcription of the JFIF
