NAME
pamchannel - extract channels from a PAM image
SYNOPSIS
pamchannel
[-infile infile]
[-tupletype tupletype]
[channum ...]
All options may be abbreviated to the shortest unique prefix.
DESCRIPTION
Reads a PAM or PNM image as input. Produces a PAM image as output,
consisting of the indicated channels (planes) of the input.
The output is the same dimensions as the input, except that the depth
is the number of channum arguments you supply. The tuple type
is a null string unless you specify the -tupletype option.
pamstack does the opposite of pamchannel: It takes multiple
PAM or PNM images as input and stacks their planes (channels) on top of
one another to yield a single PAM.
OPTIONS
- -infile infile
-
This specifies the input file, which defaults to Standard Input. You
may specify - to select Standard Input explicitly.
This is a little unconventional for Netpbm programs, which usually
have the input file specification as an argument. For pamchannel,
the arguments are channel numbers.
- -tupletype tupletype
-
This specified the tuple type name to be recorded in the output. You may
use any string up to 255 characters. Some programs recognize some names.
If you omit this option, the default tuple type name is null.
