PNGQUANT(1)						      General Commands Manual						       PNGQUANT(1)

NAME

       pngquant - PNG image optimising utility

SYNOPSIS

       pngquant [ options ] <ncolors> [pngfile [pngfile ...]]
       pngquant [ options ] -map mapfile [pngfile [pngfile ...]]

       Note that it's required to specify the number of colors (<ncolors>) or the mapfile. Arguments in square brackets are optional.

DESCRIPTION

       This manual page documents briefly the pngquant command.

       pngquant  quantizes  one or more 32-bit RGBA PNGs to 8-bit (or smaller) RGBA-palette PNGs using either ordered dithering or Floyd-Steinberg
       diffusion dithering (default). The output filename is the same as the input name except that it ends in -fs8.png or  -or8.png  (unless  the
       input  is  stdin, in which case the quantized image will go to stdout).	The default behavior if the output file exists is to skip the con-
       version; use -force to overwrite.

OPTIONS

       -force Overwrite existing output files.

       -ordened, -nofloyd, -nofs
	      Use ordered dithering.

       -verbose, -noquiet
	      Print status messages.

       NOTE:  the -map option is NOT YET SUPPORTED.

EXAMPLE

       Creating a new image with the number of colors reduced to 64:

	    pngquant 64 image.png

       The resulting image will have 64 colors and will be saved as image-fs8.png.
