<H2>NAME</H2>
pnmarith - perform arithmetic on two PNM images
<H2>DESCRIPTION</H2>
<p>This program is part of <a href="index.html">Netpbm</a>.
<P>Starting with Netpbm 10.3, <b>pnmarith</b> is obsolete. Use
<a href="pamarith.html"><b>pamarith</b></a> instead.
<b>pamarith</b> is backward compatible with <b>pnmarith</b> except where
your input images have different depths. <b>pnmarith</b> would convert
the one with the lesser depth to have the higher depth before doing the
arithmetic. With <b>pamarith</b>, you must do that step separately, using
<b>pgmtoppm</b>.
