NAME

       pnmquant - quantize the colors in a Netpbm image to a smaller set

SYNOPSIS

       pnmquant             [-center|-meancolor|-meanpixel]             [-floyd|-fs]            [-nofloyd|-nofs]
       [-spreadbrightness|-spreadluminosity] ncolors [pnmfile]

       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

       Reads a PNM image as input.  Chooses ncolors colors to best represent the image, maps the existing colors
       to the new ones, and writes a PNM image as output.

       This program is simply a combination of pnmcolormap and pnmremap, where  the  colors  of  the  input  are
       remapped  using  a color map which is generated from the colors in that same input.  The options have the
       same meaning as in those programs.  See their documentation to understand pnmquant.

       It is much faster to call pnmcolormap and pnmremap directly than to run pnmquant.   pnmquant  is  just  a
       convenience.

       ppmquant  is  an  older  program  which  does the same thing as pnmquant, but on only PPM images.  It is,
       however, faster than either pnmquant or ppmcolormap/pnmremap.
