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. REFERENCES
