1908%  adjusted to match the virtual canvas offsets of each layer. As such the

1913%  list of 'layer images' into the destiantioni images.  This makes it well

1915%  Animations' onto a static or other 'Coaleased Animation' destination image
1916%  list.  GIF disposal handling is not looked at.
1917%
1918%  Special case:- If one of the image sequences is the last image (just a
1919%  single image remaining), that image is repeatally composed with all the
1920%  images in the other image list.  Either the source or destination lists may
1921%  be the single image, for this situation.
1922%
1923%  In the case of a single destination image (or last image given), that image
1924%  will ve cloned to match the number of images remaining in the source image
1925%  list.

2564%  MagickDistortImage() distorts an image using various distortion methods, by
2565%  mapping color lookups of the source image to a new destination image
2566%  usally of the same size as the source image, unless 'bestfit' is set to
2567%  true.
2568%
2569%  If 'bestfit' is enabled, and distortion allows it, the destination image is
2570%  adjusted to ensure the whole source 'image' will just fit within the final
2571%  destination image, which will be sized and offset accordingly.  Also in
2572%  many cases the virtual offset of the source image will be taken into
2573%  account in the mapping.

2584%

2586%
2587%        ArcDistortion always ignores the source image offset, and always
2588%        'bestfit' the destination image with the top left corner offset
2589%        relative to the polar mapping center.
2590%
2591%        Bilinear has no simple inverse mapping so it does not allow 'bestfit'
2592%        style of image distortion.

2598%        Perspective, and Bilinear, falls back to a Affine distortion when less

6270%  MagickLevelImage() adjusts the levels of an image by scaling the colors
6271%  falling between specified white and black points to the full available
6272%  quantum range. The parameters provided represent the black, mid, and white
6273%  points. The black point specifies the darkest color in the image. Colors
6274%  darker than the black point are set to zero. Mid point specifies a gamma
6275%  correction to apply to the image.  White point specifies the lightest color
6276%  in the image. Colors brighter than the white point are set to the maximum
6277%  quantum value.

6570%  MagickModulateImage() lets you control the brightness, saturation, and hue
6571%  of an image.  Hue is the percentage of absolute rotation from the current
6572%  position.  For example 50 results in a counter-clockwise rotation of 90
6573%  degrees, 150 results in a clockwise rotation of 90 degrees, with 0 and 200
6574%  both resulting in a rotation of 180 degrees.
6575%
6576%  To increase the color brightness by 20% and decrease the color saturation by
6577%  10% and leave the hue unchanged, use: 120,90,100.

7281%  MagickOrderedPosterizeImage() performs an ordered dither based on a number
7282%  of pre-defined dithering threshold maps, but over multiple intensity levels,
7283%  which can be different for different channels, according to the input
7284%  arguments.
7285%
7286%  The format of the MagickOrderedPosterizeImage method is:
7287%
7288%      MagickBooleanType MagickOrderedPosterizeImage(MagickWand *wand,
7289%        const char *threshold_map)
7290%
7291%  A description of each parameter follows:
7292%
7293%    o image: the image.
7294%
7295%    o threshold_map: A string containing the name of the threshold dither
7296%      map to use, followed by zero or more numbers representing the number of
7297%      color levels tho dither between.
7298%
7299%      Any level number less than 2 is equivalent to 2, and means only binary
7300%      dithering will be applied to each color channel.
7301%
7302%      No numbers also means a 2 level (bitmap) dither will be applied to all
7303%      channels, while a single number is the number of levels applied to each
7304%      channel in sequence.  More numbers will be applied in turn to each of
7305%      the color channels.
7306%
7307%      For example: "o3x3,6" generates a 6 level posterization of the image
7308%      with a ordered 3x3 diffused pixel dither being applied between each
7309%      level. While checker,8,8,4 will produce a 332 colormaped image with
7310%      only a single checkerboard hash pattern (50% grey) between each color
7311%      level, to basically double the number of color levels with a bare
7312%      minimim of dithering.
