ppmquantall(1)                                                General Commands Manual                                               ppmquantall(1)

NAME

       ppmquantall - run ppmquant on a bunch of files all at once, so they share a common colormap

SYNOPSIS

       ppmquantall [-ext extension] ncolors ppmfile ...

DESCRIPTION

       Takes a bunch of portable pixmap as input.  Chooses ncolors colors to best represent all of the images, maps the existing colors to the new
       ones, and overwrites the input files with the new quantized versions.

       If you don't want to overwrite your input files, use the -ext option.  The output files are then named the same as the input files, plus  a
       period and the extension text you specify.

       Verbose  explanation:  Let's  say  you've got a dozen pixmaps that you want to display on the screen all at the same time.  Your screen can
       only display 256 different colors, but the pixmaps have a total of a thousand or so different colors.  For a single pixmap you  solve  this
       problem  with  ppmquant;  this  script  solves  it for multiple pixmaps.  All it does is concatenate them together into one big pixmap, run
       ppmquant on that, and then split it up into little pixmaps again.

       (Note that another way to solve this problem is to pre-select a set of colors and then use ppmquant's -map option  to  separately  quantize
       each pixmap to that set.)
