NAME

       ppmpat - make a pretty PPM image



SYNOPSIS

       ppmpat {-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.



OPTIONS

       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.
