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.
