NAME
ppmpat - make a pretty pixmap
SYNOPSIS
ppmpat -gingham2|-g2|-gingham3| -g3|-madras|-tartan| -poles|-squig|-camo|
-anticamo width height
----- ------
DESCRIPTION
Produces a portable pixmap 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 | ppmquant 128 should generate a nice background.
OPTIONS
The different flags specify various different 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. May need to be
run through ppmquant.
--------
-squig
Squiggley tubular pattern. Can be tiled. May need to be run
through ppmquant.
--------
-camo
Camouflage pattern. May need to be run through ppmquant.
--------
-anticamo
Anti-camouflage pattern - like -camo, but ultra-bright colors. May
need to be run through ppmquant.
--------
All flags can be abbreviated to their shortest unique prefix.
REFERENCES
Some of the patterns are from "Designer's Guide to Color 3" by Jeanne
Allen.
