DESCRIPTION
.LP
.LP
This program is part of Netpbm.
.LP
\fBsgitopnm\fR 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.
.LP
Alternatively, the program produces a PGM image of any one of the
channels in the input file.
.SH 2
OPTIONS
.LP
.RS
.IP "\fB-verbose\fR"
Give some information about the SGI image file.
.IP "\fB-channel\fR \fIc\fR"
Extract channel \fIc\fR of the image as a PGM image.  Without
this option, \fBsgitopnm\fR 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.
