NAME
macptopbm - convert a MacPaint file into a PBM image
SYNOPSIS
macptopbm [-extraskip N] [macpfile]
DESCRIPTION
This program is part of Netpbm(1).
macptopbmreads a MacPaint file as input and produces a PBM image as
output.
OPTIONS
In addition to the options common to all programs based on libnetpbm
(most notably -quiet, see
Common Options ⟨index.html#commonoptions⟩ ), macptopbm recognizes the
following command line option:
You can abbreviate any option to its shortest unique prefix.
-extraskip
This option 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.
