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


   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


   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


   pnmcolormap(1), pnmremap(1), ppmquantall(1), pnmdepth(1), ppmdither(1),
   ppmquant(1), pnm(5)
