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

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

       This program is part of Netpbm(1)

       pnmquant reads a PNM image as input.  It chooses ncolors  colors  to  best  represent  the
       image, maps the existing colors to the new ones, and writes a PNM image as output.

       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.

       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.   You
       save  the  overhead of the Perl interpreter and creating two extra processes.  pnmquant is
       just a convenience.

       pnmquant did not exist before Netpbm 9.21 (January 2001).  Before that, ppmquant  did  the
       same  thing, but only on PPM images.  ppmquant continues to exist, but is only a front end
       (for name compatibility) to pnmquant.
