PICTTOPBM

NAME

      picttopbm - convert a PICT file into a portable bitmap

SYNOPSIS

      picttopbm [-extraskip <n>] [pictfile]

DESCRIPTION

      Reads a PICT file as input.  Produces a portable bitmap as output.
      Note that PICT is a drawing format, not an image format, so this
      program interprets a very small subset of the operators.  However,
      this subset includes the operators used by such programs as SuperPaint
      and AppleScan when writing out bitmap images so it's not totally
      useless.
      The -extraskip flag is to get around a problem with some methods of
      transfering 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 -e 128, and if that still doesn't look right try
      another value.
      All flags can be abbreviated to their shortest unique prefix.

BUGS

      This should really be promoted to picttoppm, and fixed to handle
      PICT2.  Most of the hoocks are already in.
