       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)
