URT is a collection of programs and C routines for dealing with raster images commonly encountered in computer graphics. A device and system independent image format stores images and information about them. Called the RLE format it uses run length encoding to reduce storage space for most images. Most of the supplied tools read one or more input RLE file and produce an output RLE file. Some generate RLE files from other information, and some read RLE files and produce output in a different format.
