ppmpat - make a pretty PPM image
ppmpat {-gingham2|-g2} | {-gingham3|-g3} | -madras | -tartan | -poles | -squig | -camo | -anticamo width height
You can abbreviate any option to its shortest unique prefix.
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 ppmpat -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.
The options
specify various pattern types:
-gingham2
A gingham check pattern. Can be tiled.
-gingham3
A slightly more complicated gingham. Can be tiled.
-madras
A madras plaid. Can be tiled.
-tartan
A tartan plaid. Can be tiled.
|
-poles |
Color gradients centered on randomly-placed poles. |
|||
|
-squig |
Squiggley tubular pattern. Can be tiled. |
|||
|
-camo |
Camouflage pattern. |
-anticamo
Anti-camouflage pattern - like -camo, but ultra-bright colors.
Some of the patterns are from ’Designer’s Guide to Color 3’ by Jeanne Allen.
