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.

BUGS

Currently, no bugs are known.

ACKNOWLEDGEMENT

Jef Poskanzer is the initiator and main implementor of the PBM package that contains various image processing routines and printer drivers.
