48x48x1 Image Compression and Decompression
The programs compface and uncompface convert 48x48x1 images to and from
a compressed format. The purpose of the programs is to allow the
inclusion of face images within mail headers using the field name
"X-face:". They make use of a library that allows the compression and
decompression algorithms to be used in other programs, such as mail
dispatchers and mail notification daemons.
