pbmmake

pbmmake [-white|-black|-gray ] width height

Produces a portable bitmap of the specified width and height. The color defaults to white.

In addition to the usual -white and -black, this program implements -gray. This gives a simple 50% gray pattern with 1's and 0's alternating.

All flags can be abbreviated to their shortest unique prefix.
