DESCRIPTION

20       This program is part of Netpbm(1).
21
22       sgitopnm  reads an SGI image file as input and produces a PGM image for
23       a 2-dimensional (1 channel) input file, and a PPM image for a  3-dimen‐
24       sional (3 or more channels) input file.
25
26       Alternatively, the program produces a PGM image of any one of the chan‐
27       nels in the input file.

OPTIONS

31       -verbose
32              Give some information about the SGI image file.
33
34
35       -channel c
36              Extract channel c of the image as a  PGM  image.   Without  this
37              option,  sgitopnm  extracts  the first 3 channels as a PPM image
38              or, if the input has only 1 channel,  extracts  that  as  a  PGM
39              image, and if the input has 2 channels, fails.
