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  Macbi‐
       nary 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 ),
       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 image.

	      Without -norle, MacPaint compresses the image as much as possible 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, start‐
	      ing at the specified top left corner.

	      These options exist for backward compatibility with an unfortunate 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 version, using different logic and none of the origi‐
       nal  code.   The	 new version used the "packed PBM" facilities of the Netpbm library and the shhopt method of command
       line parsing.
