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 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 ppmcolormap/pnmremap.
