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  under-
       stand 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.
