If you need to reduce an RGB file to a paletted file, or if a paletted
file has more entries then will fit on your screen, png_set_dither()
will do that. Note that this is a simple match dither that merely
finds the closest color available. This should work fairly well with
optimized palettes, and fairly badly with linear color cubes. If you
pass a palette that is larger then maximum_colors, the file will
reduce the number of colors in the palette so it will fit into
maximum_colors. If there is a histogram, it will use it to make
more intelligent choices when reducing the palette. If there is no
histogram, it may not do as good a job.

If you need to reduce an RGB file to a paletted file, or if a paletted
file has more entries then will fit on your screen, png_set_dither()
will do that. Note that this is a simple match dither that merely
finds the closest color available. This should work fairly well with
optimized palettes, and fairly badly with linear color cubes. If you
pass a palette that is larger then maximum_colors, the file will
reduce the number of colors in the palette so it will fit into
maximum_colors. If there is a histogram, it will use it to make
more intelligent choices when reducing the palette. If there is no
histogram, it may not do as good a job.
