macptopbm(1)                                         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 "finder-
              info"  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 pre-
       fix.
