NAME
        pamchannel - extract channels from a PAM image
 
 
SYNOPSIS
        pamchannel [ -infile infile ] [channum] ...
 
        All options may be abbreviated to the shortest unique pre­
        fix.
 
 
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.
