<H2>DESCRIPTION</H2>
<p>This program is part of <a href="index.html">Netpbm</a>.
<p><b>xpbtoppm</b> reads an X11 pixmap (XPM version 1 or 3) as input
and produces a PPM image as output.
<A NAME="lbAE"> </A>
<H2>OPTIONS</H2>
<DL COMPACT>
<DT><B>--alphaout=</B><I>alpha-filename</I>
<DD><B>xpmtoppm</B> creates a PBM file containing the transparency
mask for the image. If the input image doesn't contain transparency
information, the <I>alpha-filename</I> file contains all white
(opaque) alpha values. If you don't specify <B>--alphaout</B>,
<B>xpmtoppm</B> does not generate an alpha file, and if the input
image has transparency information, <B>xpmtoppm</B> simply discards
it.
<P>If you specify <B>-</B> as the filename, <B>xpmtoppm</B> writes the
alpha output to Standard Output and discards the image.
<P>See <B><A HREF="pamcomp.html">pamcomp</A></B> for one way to use
the alpha output file.
<p><b>xpmtoppm</b> can't handle a line longer than 8K characters in
the the XPM input. If an input line exceeds this limit,
<b>xpmtoppm</b> quits with an error message to that effect. Before
Netpbm 10.30 (October 2005), the limit was 2K.
<DT><B>--verbose</B>
<DD>
<B>xpmtoppm</B> prints information about its processing on Standard Error.
</DL>
<A NAME="lbAF"> </A>
<H2>LIMITATIONS</H2>
<p>The recogized XPM version 3 features are limited. Comments can
only be single lines and there must be for every pixel a default
colorname for a color type visual.
