<H2>DESCRIPTION</H2>
<p>This program is part of <a href="index.html">Netpbm</a>.
<p><b>sgitopnm</b> reads an SGI image file as input and produces a PGM
image for a 2-dimensional (1 channel) input file, and a PPM image for
a 3-dimensional (3 or more channels) input file.
<P>Alternatively, the program produces a PGM image of any one of the
channels in the input file.

<H2>OPTIONS</H2>

<DT><B>-verbose</B>
<DD>Give some information about the SGI image file.
<DT><B>-channel</B> <I>c</I>
<DD>Extract channel <I>c</I> of the image as a PGM image. Without
this option, <B>sgitopnm</B> extracts the first 3 channels as a PPM
image or, if the input has only 1 channel, extracts that as a PGM
image, and if the input has 2 channels, fails.
