This package contains C software to implement JPEG image compression and
decompression. JPEG is a standardized compression method for full-color
and gray-scale images. JPEG is intended for "real-world" scenes; cartoons
and other non-realistic images are not its strong suit. JPEG is lossy,
meaning that the output image is not identical to the input image.
The user can trade off output image quality against compressed file size
by adjusting a compression parameter.
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.
