pnmquant(1)                          General Commands Manual                          pnmquant(1)

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

SYNOPSIS
       pnmquant  [-center|-meancolor|-meanpixel]  [-floyd|-fs]  [-nofloyd|-nofs]  [-spreadbright-
       ness|-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 be-
       tween 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  in-
       put.   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.   pn-
       mquant is just a convenience.

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