<H2>DESCRIPTION</H2>
<p>This program is part of <a href="index.html">Netpbm</a>.
<p><b>ppmpat</b> produces a PPM of the specified width and height,
with a pattern in it.
<P>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
<B>ppmpat -squig 300 300 | pnmquant 128</B>
should generate a nice background.
<p>Some of these patterns have large numbers of colors, so if you want
a simpler pattern, use <b>pnmquant</b> on the output.
<A NAME="lbAE"> </A>
<H2>OPTIONS</H2>
<P>The options specify various pattern types:
<DL COMPACT>
<DT><B>-gingham2</B>

<DT><B>-gingham3</B>
