|
|
|
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.
|
|
<P>
|
|
Alternatively, produces a PGM image of any one of the channels in the
|
|

of the image as a PGM image. Without this option,

<B>sgitopnm</B>
|
|

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.
