JPEG Library
Independent JPEG Group’s free JPEG software
-------------------------------------------
This package contains C software to implement JPEG image encoding, decoding, and transcoding. JPEG is a 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 [e-mail].
