NAME
pbmtomacp - convert a PBM image to a MacPaint file
SYNOPSIS
pbmtomacp [-left left]
[-right right]
[-top top]
[-bottom bottom]
[pbmfile]
All options can be abbreviated to their shortest unique prefix. You
may use two hyphens instead of one to designate an option. You may use
either white space or equals signs between an option name and its
value.
DESCRIPTION
This program is part of Netpbm(1).
pbmtomacp reads a PBM image as input and produces a MacPaint file as
output.
If you do not specify pbmfile, pbmtomacp uses Standard Input.
The generated file is only the data fork of a picture. You will need
a program such as mcvert to generate a Macbinary or a BinHex file that
contains the necessary information to identify the file as a PNTG file
to MacOS.
OPTIONS
In addition to the options common to all programs based on libnetpbm
(most notably -quiet, see
Common Options ⟨index.html#commonoptions⟩ ), pbmtomacp recognizes the
following command line options:
-norle This option tells pbmtomacp not to use any run length encoding
compression in the MacPaint image it produces. This output,
while not normal, conforms to MacPaint specifications and can be
read by any MacPaint decoder without any special settings.
The only value of this option is testing and experimentation.
The option causes every output image to contain exactly 53072
bytes, which is the theoretical maximum size for a MacPaint im-
age.
Without -norle, MacPaint compresses the image as much as possi-
ble and the output size depends on the nature of the input.
-left -right -top -bottom These options let you define a rectangle
within the image to convert. The default is the whole file. If
the specified image is too large for a MacPaint-file, pbmtomacp
cuts the image to fit, starting at the specified top left cor-
ner.
These options exist for backward compatibility with an unfortu-
nate original design. They do the same thing that you can do in
a more Netpbm-like way and more flexibly by processing the input
through pamcut.

HISTORY
pbmtomacp was added to Netpbm in 1988, written by Douwe van der Schaaf
(...!mcvax!uvapsy!vdschaaf).
In 2015, Akira Urushibata replaced the program with the current ver-
sion, using different logic and none of the original code. The new
version used the "packed PBM" facilities of the Netpbm library and the
shhopt method of command line parsing.
