The programme (two programmes really - but they're just links to each other) converts 48x48x1 images to and from a compressed format. The uncompressed images are expected to contain 48x48/4 (576) hex digits. All other characters and any `0's followed by `X' or `x' are ignored. Usually the files are 48 lines of "0x%04X,0x%04X,0x%04X,". The compressed images contain some number of printable characters. Non printable characters, including ` ' are ignored. The purpose of the programme is to allow the inclusion of face images within mail headers using the field name `X-face: '.
