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 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.
