SYNOPSISppmpat {-gingham2|-g2} | {-gingham3|-g3} | -madras | -tartan | -poles |
-squig | -camo | -anticamo width height
You can abbreviate any option to its shortest unique prefix.
DESCRIPTION
This program is part of Netpbm(1)ppmpat produces a PPM of the specified width and height, with a pattern
in it.
This program is mainly to demonstrate use of the ppmdraw routines, a
simple but powerful drawing library. See the ppmdraw.h include file
for more info on using these routines. Still, some of the patterns can
be rather pretty. If you have a color workstation, something like ppm‐
pat -squig 300 300 | pnmquant 128 should generate a nice background.
Some of these patterns have large numbers of colors, so if you want a
simpler pattern, use pnmquant on the output.
