Manpages pnmcropSection: User Commands (1)Updated: 18 March 2001 Index Return to Main Contents NAMEpnmcrop - crop a portable anymapSYNOPSISpnmcrop [-white|-black|-sides] [-left] [-right] [-top] [-bottom] [pnmfile]All options may be abbreviated to their shortest unique prefix or specified with double hyphens. DESCRIPTIONReads a PBM, PGM, or PPM image as input. Removes borders that are the background color, and produces the same type of image as output.If you don't specify otherwise, pnmcrop assumes the background color is whatever color the top left and right corners of the image are and if they are different colors, something midway between them. You can specify that the background is white or black with the -white and -black options or make pnmcrop base its guess on all four corners instead of just two with -sides. By default, pnmcrop chops off any stripe of background color it finds, on all four sides. You can tell pnmcrop to remove only specific borders with the -left, -right, -top, and -bottom options. If you want to chop a specific amount off the side of an image, use pnmcut. If you want to add different borders after removing the existing ones, use pnmcat or pnmcomp. OPTIONS
