%  MagickConstituteImage() adds an image to the wand comprised of the pixel
%  data you supply.  The pixel data must be in scanline order top-to-bottom.

%  require the pixels to be normalized [0..1], otherwise [0..Max],  where Max
%  is the maximum value the type can accomodate (e.g. 255 for char).  For
%  example, to create a 640x480 image from unsigned red-green-blue character

%
%    o columns: width in pixels of the image.
%
%    o rows: height in pixels of the image.
%
%    o map:  This string reflects the expected ordering of the pixel array.

%      Y = yellow, M = magenta, K = black, I = intensity (for grayscale),
%      P = pad.
%
%    o storage: Define the data type of the pixels.  Float and double types are
%      expected to be normalized [0..1] otherwise [0..QuantumRange].  Choose from
%      these types: CharPixel, DoublePixel, FloatPixel, IntegerPixel,
%      LongPixel, QuantumPixel, or ShortPixel.
%
%    o pixels: This array of values contain the pixel components as defined by
%      map and type.  You must preallocate this array where the expected
%      length varies depending on the values of width, height, map, and type.

%  MagickDistortImage() distorts an image using various distortion methods, by
%  mapping color lookups of the source image to a new destination image
%  usally of the same size as the source image, unless 'bestfit' is set to
%  true.
%
%  If 'bestfit' is enabled, and distortion allows it, the destination image is
%  adjusted to ensure the whole source 'image' will just fit within the final
%  destination image, which will be sized and offset accordingly.  Also in
%  many cases the virtual offset of the source image will be taken into
%  account in the mapping.
%
%  The format of the MagickDistortImage method is:
%
%      MagickBooleanType MagickDistortImage(MagickWand *wand,
%        const DistortImageMethod method,const size_t number_arguments,
%        const double *arguments,const MagickBooleanType bestfit)
%
%  A description of each parameter follows:
%
%    o image: the image to be distorted.
%
%    o method: the method of image distortion.
%
%        ArcDistortion always ignores the source image offset, and always
%        'bestfit' the destination image with the top left corner offset
%        relative to the polar mapping center.
%
%        Bilinear has no simple inverse mapping so it does not allow 'bestfit'
%        style of image distortion.
%
%        Affine, Perspective, and Bilinear, do least squares fitting of the
%        distortion when more than the minimum number of control point pairs
%        are provided.
%
%        Perspective, and Bilinear, falls back to a Affine distortion when less
%        that 4 control point pairs are provided. While Affine distortions let
%        you use any number of control point pairs, that is Zero pairs is a
%        no-Op (viewport only) distrotion, one pair is a translation and two
%        pairs of control points do a scale-rotate-translate, without any
%        shearing.
%
%    o number_arguments: the number of arguments given for this distortion
%      method.
%
%    o arguments: the arguments for this distortion method.
%
%    o bestfit: Attempt to resize destination to fit distorted source.

%
%  A description of each parameter follows:

%    o wand: the magick wand.
%
%    o x, y, columns, rows:  These values define the perimeter

%
%    o map:  This string reflects the expected ordering of the pixel array.
%      It can be any combination or order of R = red, G = green, B = blue,

%
%    o storage: Define the data type of the pixels.  Float and double types are
%      expected to be normalized [0..1] otherwise [0..QuantumRange].  Choose from
%      these types: CharPixel, DoublePixel, FloatPixel, IntegerPixel,

%
%    o pixels: This array of values contain the pixel components as defined by

%  MagickImportImagePixels() accepts pixel datand stores it in the image at the
%  location you specify.  The method returns MagickFalse on success otherwise
%  MagickTrue if an error is encountered.  The pixel data can be either char,
%  short int, int, ssize_t, float, or double in the order specified by map.
%
%  Suppose your want to upload the first scanline of a 640x480 image from
%  character data in red-green-blue order:
%
%      MagickImportImagePixels(wand,0,0,640,1,"RGB",CharPixel,pixels);
%
%  The format of the MagickImportImagePixels method is:
%
%      MagickBooleanType MagickImportImagePixels(MagickWand *wand,
%        const ssize_t x,const ssize_t y,const size_t columns,
%        const size_t rows,const char *map,const StorageType storage,
%        const void *pixels)
%
%  A description of each parameter follows:
%
%    o wand: the magick wand.
%
%    o x, y, columns, rows:  These values define the perimeter of a region
%      of pixels you want to define.
%
%    o map:  This string reflects the expected ordering of the pixel array.
%      It can be any combination or order of R = red, G = green, B = blue,
%      A = alpha (0 is transparent), O = opacity (0 is opaque), C = cyan,
%      Y = yellow, M = magenta, K = black, I = intensity (for grayscale),
%      P = pad.
%
%    o storage: Define the data type of the pixels.  Float and double types are
%      expected to be normalized [0..1] otherwise [0..QuantumRange].  Choose from
%      these types: CharPixel, ShortPixel, IntegerPixel, LongPixel, FloatPixel,
%      or DoublePixel.
%
%    o pixels: This array of values contain the pixel components as defined by
%      map and type.  You must preallocate this array where the expected
%      length varies depending on the values of width, height, map, and type.

%
%  MagickOrderedPosterizeImage() performs an ordered dither based on a number
%  of pre-defined dithering threshold maps, but over multiple intensity levels,
%  which can be different for different channels, according to the input
%  arguments.
%
%  The format of the MagickOrderedPosterizeImage method is:
%
%      MagickBooleanType MagickOrderedPosterizeImage(MagickWand *wand,
%        const char *threshold_map)
%      MagickBooleanType MagickOrderedPosterizeImageChannel(MagickWand *wand,
%        const ChannelType channel,const char *threshold_map)
%
%  A description of each parameter follows:
%
%    o image: the image.
%
%    o channel: the channel or channels to be thresholded.
%
%    o threshold_map: A string containing the name of the threshold dither
%      map to use, followed by zero or more numbers representing the number of
%      color levels tho dither between.
%
%      Any level number less than 2 is equivalent to 2, and means only binary
%      dithering will be applied to each color channel.
%
%      No numbers also means a 2 level (bitmap) dither will be applied to all
%      channels, while a single number is the number of levels applied to each
%      channel in sequence.  More numbers will be applied in turn to each of
%      the color channels.
%
%      For example: "o3x3,6" generates a 6 level posterization of the image
%      with a ordered 3x3 diffused pixel dither being applied between each
%      level. While checker,8,8,4 will produce a 332 colormaped image with
%      only a single checkerboard hash pattern (50% grey) between each color
%      level, to basically double the number of color levels with a bare
%      minimim of dithering.

%  MagickSparseColorImage(), given a set of coordinates, interpolates the
%  colors found at those coordinates, across the whole image, using various
%  methods.
%
%  The format of the MagickSparseColorImage method is:
%
%      MagickBooleanType MagickSparseColorImage(MagickWand *wand,
%        const ChannelType channel,const SparseColorMethod method,
%        const size_t number_arguments,const double *arguments)
%
%  A description of each parameter follows:
%
%    o image: the image to be sparseed.
%
%    o method: the method of image sparseion.
%
%        ArcSparseColorion will always ignore source image offset, and always
%        'bestfit' the destination image with the top left corner offset
%        relative to the polar mapping center.
%
%        Bilinear has no simple inverse mapping so will not allow 'bestfit'
%        style of image sparseion.
%
%        Affine, Perspective, and Bilinear, will do least squares fitting of
%        the distrotion when more than the minimum number of control point
%        pairs are provided.
%
%        Perspective, and Bilinear, will fall back to a Affine sparseion when
%        less than 4 control point pairs are provided. While Affine sparseions
%        will let you use any number of control point pairs, that is Zero pairs
%        is a No-Op (viewport only) distrotion, one pair is a translation and
%        two pairs of control points will do a scale-rotate-translate, without
%        any shearing.
%
%    o number_arguments: the number of arguments given for this sparseion
%      method.
%
%    o arguments: the arguments for this sparseion method.
