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.
