- From the JPEG FAQ, posted regularly in comp.graphics and news.answers
- (not to mention a lot of alt groups):
-
-
- 6) Where can I get JPEG software?
-
- 6B) If you are looking for source code to work with:
-
- Free, portable C code for JPEG compression is available from the Independent
- JPEG Group, which I lead. A package containing our source code,
- documentation, and some small test files is available from several places.
- The "official" archive site for this source code is ftp.uu.net (137.39.1.9
- or 192.48.96.9). Look under directory /graphics/jpeg; the current release
- is jpegsrc.v3.tar.Z. (This is a compressed TAR file; don't forget to
- retrieve in binary mode.) You can retrieve this file by FTP or UUCP.
- Folks in Europe may find it easier to FTP from nic.funet.fi (see directory
- pub/graphics/programs/jpeg). The source code is also available on
- CompuServe, in the GRAPHSUPPORT forum (GO PICS), library 10, as jpsrc3.zip.
- If you have no FTP access, you can retrieve the source from your nearest
- comp.sources.misc archive; version 3 appeared as issues 1-18 of volume 29.
- (If you don't know how to retrieve comp.sources.misc postings, see the FAQ
- article "How to find sources". This appears regularly in news.answers, or
- you can get it by sending e-mail to mail-server@rtfm.mit.edu with
- "send usenet/news.answers/finding-sources" in the body.)
-
- The free JPEG code provides conversion between JPEG "JFIF" format and image
- files in GIF, PBMPLUS PPM/PGM, Utah RLE, and Truevision Targa file formats.
- The core compression and decompression modules can easily be reused in other
- programs, such as image viewers. The package is highly portable; we have
- tested it on many machines ranging from PCs to Crays.
-
- We have released 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.
-
- The Independent JPEG Group is a volunteer organization; if you'd like to
- contribute to improving our software, you are welcome to join.
