man pbmshift (Commandes) - shift a PBM-P4-file to the right lower corner
NAME
pbmshift - shift a PBM-P4-file to the right lower corner
SYNOPSIS
pbmshift infile topmargin leftmargin outfile
DESCRIPTION
Pbmshift reads a PBM file in P4 format and produces a new PBM file in P4 format. The output is shifted to the right by leftmargin pixels and to the lower by topmargin pixels. This tool can be used to modify the image produced as export output of the VCG tool from a graph before printing it on paper. In this way, margins can be produced to position the image on the paper. Negative margins are allowed.
WARNING
This utility does not work with the PBM-P1-format !!! It is not a general conversion utility but only a small demonstation how to deal with the output of the VCG tool. There are excellent standard utilities for PBM-Files by Jef Poskanzer (pnmmargin) but pbmshift should be much faster on large files.

ACKNOWLEDGEMENT
