!!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.
