- ==========
-
- The best and most readily available introduction to the JPEG compression
- algorithm is Wallace's article in the April '91 CACM:
- Wallace, Gregory K. "The JPEG Still Picture Compression Standard",
- Communications of the ACM, April 1991 (vol. 34 no. 4), pp. 30-44.
- (Adjacent articles in that issue discuss MPEG motion picture compression,
- applications of JPEG, and related topics.) We highly recommend reading that
- article before looking at any of the JPEG software.
-
- For more detail about the JPEG standard you pretty much have to go to the
- draft standard, which is not nearly as intelligible as Wallace's article.
- The current version is ISO/IEC Committee Draft CD 10918-1 dated 1991-03-15.
- The standard is not presently available electronically; you must order a paper
- copy through ISO.
-
- The JPEG standard does not specify all details of an interchangeable file
- format. For the omitted details we follow the "JFIF" conventions, revision
- 1.01. A copy of the JFIF spec is available from:
- Literature Department
- C-Cube Microsystems, Inc.
- 399A West Trimble Road
- San Jose, CA 95131
- (408) 944-6300
- Requests can also be e-mailed to info@c3.pla.ca.us (this address good after
- 10/10/91). The same source can supply copies of the draft JPEG-in-TIFF specs.

- If you want to understand this implementation, start by reading the
- "architecture" documentation file. Please read "codingrules" if you want to
- contribute any code.
