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.
