DESCRIPTION
Reads a PAM or PNM image as input. Produces a PAM image
as output, consisting of the indicated channels of the
input.
The output is the same dimensions as the input, except
that the depth is the number of channum arguments you sup
ply. The tuple type is a null string.
OPTIONS-infile infile
This specifies the input file, which defaults to
Standard Input. You may specify - to select Stan
dard Input explicitly.
This is a little unconventional for Netpbm pro
grams, which usually have the input file specifica
tion as an argument. For pamchannel, the arguments
are channel numbers.
