<H2>DESCRIPTION</H2>
<p>This program is part of <a href="index.html">Netpbm</a>.
<p><b>ximptoppm</b> reads an Xim file as input and produces a PPM
image as output. The Xim toolkit is included in the contrib tree of
the X.V11R4 release.

<H2>OPTIONS</H2>
<P>You can abbreviate any option to its shortest unique prefix.
<DL COMPACT>
<DT><B>--alphaout=</B><I>alpha-filename</I>
<DD><B>ximtoppm</B> creates a PGM file containing the transparency channel
values in the input image. If the input image doesn't contain a
transparency channel, the <I>alpha-filename</I> file contains all zero
(transparent) transparency values. If you don't specify <B>--alphaout</B>,
<B>ximtoppm</B> does not generate a transparency file, and if the input
image has a transparency channel, <B>ximtoppm</B> simply discards it.
<P>If you specify <B>-</B> as the filename, <B>ximtoppm</B> writes the
transparency output to Standard Output and discards the image.
<P>Actually, an Xim image can contain an arbitrary fourth channel --
it need not be a transparency channel. <B>ximtoppm</B> extracts any fourth
channel it finds as described above; it doesn't matter if it is a
transparency channel or not.
<P>See <B><A HREF="pamcomp.html">pamcomp</A></B> for one way to use
the transparency output file.
