PPMTOXPM

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.
