NAME
       pnmcrop - crop a portable anymap

SYNOPSIS
       pnmcrop  [-white|-black] [-left] [-right] [-top] [-bottom]
       [pnmfile]

DESCRIPTION
       Reads a portable anymap as input.  Removes edges that  are
       the  background  color,  and produces a portable anymap as
       output.

OPTIONS
       By default, it makes a guess as  to  what  the  background
       color  is.   You  can override the default with the -white
       and -black flags.

       The options -left, -right, -top and -bottom restrict crop-
       ping  to  the  sides specified. The default is to crop all
       sides of the image.

       All flags can be abbreviated to their shortest unique pre-
       fix.
