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.
