pnmcrop - crop a portable anymap
pnmcrop [-white|-black] [-left] [-right] [-top] [-bottom] [pnmfile]
Reads a portable anymap as input. Removes edges that are the background color, and produces a portable anymap as output.
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 cropping to the sides specified. The default is to crop all sides of the image.
All flags can be abbreviated to their shortest unique prefix.
