NAME
       sgitopnm - convert a SGI image file to a portable anymap

SYNOPSIS
       sgitopnm [-verbose] [-channel c] [SGIfile]

DESCRIPTION
       Reads  an SGI image file as input.  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.

       Alternatively, produces a PGM image of any one of the channels in the input file.

OPTIONS
       -verbose
	      Give some information about the SGI image file.

       -channel c
	      Extract channel c of the image as a PGM image.  Without this option, sgitopnm 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.
