sgitopnm - convert a SGI image file to PNM |
|
sgitopnm [-verbose] [-channel c] [SGIfile] |
|
This program is part of Netpbm(1). sgitopnm reads an SGI image file as input and 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, the program produces a PGM image of any one of the channels in the input file. |
|
-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. |
