pbmrot90 - rotates a PBM-P4-file by 90 degree
pbmrot90 infile outfile
Pbmrot90 reads a PBM file in P4 format and produces a new PBM file in P4 format.
The output is rotated by 90 degree.
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, portrait format can be converted into landscape format.
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
(pnmflip, pnmshift) but
pbmrot90 should be much faster on large files.

Currently, no bugs are known.
Jef Poskanzer is the initiator and main implementor of
the PBM package that contains various image processing
routines and printer drivers.
