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