macptopbm(1)             UNIX System V(29 March 1989)              macptopbm(1)


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.
