The bitmap program is a rudimentary tool for creating or editing
rectangular images made up of 1's and 0's. Bitmaps are used in X for
defining clipping regions, cursor shapes, icon shapes, and tile and
stipple patterns.

The bmtoa and atobm filters convert bitmap files (FILE FORMAT) to and
from ASCII strings. They are most commonly used to quickly print out
bitmaps and to generate versions for including in text.
