NAME
       macptopbm - convert a MacPaint file into a portable bitmap

SYNOPSIS
       macptopbm [-extraskip N] [macpfile]

DESCRIPTION
       Reads a MacPaint file as input.	Produces a portable bitmap as output.

OPTIONS
       -extraskip
	      This  flag  is  to get around a problem with some methods of transferring files from the Mac world to the Unix world.  Most of these
	      methods leave the Mac files alone, but a few of them add the "finderinfo" data onto the front of the Unix file.  This means an extra
	      128  bytes  to  skip over when reading the file.	The symptom to watch for is that the resulting PBM file looks shifted to one side.
	      If you get this, try -extraskip 128, and if that still doesn't look right try another value.

       All flags can be abbreviated to their shortest unique prefix.
