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.
