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 ), 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, starting 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  original  code.   The new version used the "packed PBM" facilities of the Netpbm library and the
       shhopt method of command line parsing.
