NAME
      ppmtoxpm - convert a portable pixmap into an X11 pixmap

SYNOPSIS
      ppmtoxpm [-name <xpmname>] [-rgb <rgb-textfile>] [<ppmfile>]

DESCRIPTION
      Reads a portable pixmap as input.  Produces X11 pixmap  (version 3) as
      output which can be loaded directly by the XPM library.

      The -name option allows one to specify the prefix string which is printed
      in the resulting XPM output.  If not specified, will default to the
      filename (without extension) of the <ppmfile> argument.  If -name is not
      specified and <ppmfile> is not specified (i.e. piped input), the prefix
      string will default to the string "noname".

      The -rgb option allows one to specify an X11 rgb text file for the lookup
      of color name mnemonics.  This rgb text file is typically the
      /usr/lib/X11/rgb.txt of the MIT X11 distribution, but any file using the
      same format may be used.  When specified and a RGB value from the ppm
      input matches a RGB value from the <rgb-textfile>, then the corresponding
      color name mnemonic is printed in the XPM's colormap.  If -rgb is not
      specified, or if the RGB values don't match, then the color will be
      printed with the #RGB, #RRGGBB, #RRRGGGBBB, or #RRRRGGGGBBBB hexadecimal
      format.

      All flags can be abbreviated to their shortest unique prefix.

      For example, to convert the file "dot" (found in
      /usr/include/X11/bitmaps), from xbm to xpm one could specify

            xbmtopbm dot | ppmtoxpm -name dot

      or, with a rgb text file (in the local directory)

            xbmtopbm dot | ppmtoxpm -name dot -rgb rgb.txt

BUGS
      An option to match the closest (rather than exact) color name mnemonic
      from the rgb text would be a desirable enhancement.

      Truncation of the least significant bits of a RGB value may result in
      nonexact matches when performing color name mnemonic lookups.
