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-dimen‐
sional (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.
