7457 %  MagickOrderedDitherImage() performs an ordered dither based on a number
7458 %  of pre-defined dithering threshold maps, but over multiple intensity levels,
7459 %  which can be different for different channels, according to the input
7460 %  arguments.
7461 %
7462 %  The format of the MagickOrderedDitherImage method is:
7463 %
7464 %      MagickBooleanType MagickOrderedDitherImage(MagickWand *wand,
7465 %        const char *threshold_map)
7466 %
7467 %  A description of each parameter follows:
7468 %
7469 %    o image: the image.
7470 %
7471 %    o threshold_map: A string containing the name of the threshold dither
7472 %      map to use, followed by zero or more numbers representing the number of
7473 %      color levels tho dither between.
7474 %
7475 %      Any level number less than 2 is equivalent to 2, and means only binary
7476 %      dithering will be applied to each color channel.
7477 %
7478 %      No numbers also means a 2 level (bitmap) dither will be applied to all
7479 %      channels, while a single number is the number of levels applied to each
7480 %      channel in sequence.  More numbers will be applied in turn to each of
7481 %      the color channels.
7482 %
7483 %      For example: "o3x3,6" generates a 6 level posterization of the image
7484 %      with a ordered 3x3 diffused pixel dither being applied between each
7485 %      level. While checker,8,8,4 will produce a 332 colormaped image with
7486 %      only a single checkerboard hash pattern (50% grey) between each color
7487 %      level, to basically double the number of color levels with a bare
7488 %      minimim of dithering.
