%
%  MagickBilateralBlurImage() is a non-linear, edge-preserving, and
%  noise-reducing smoothing filter for images.  It replaces the intensity of
%  each pixel with a weighted average of intensity values from nearby pixels.
%  This weight is based on a Gaussian distribution.  The weights depend not
%  only on Euclidean distance of pixels, but also on the radiometric
%  differences (e.g., range differences, such as color intensity, depth
%  distance, etc.). This preserves sharp edges.
%
%  The format of the MagickBilateralBlurImage method is:
%
%      MagickBooleanType MagickBilateralBlurImage(MagickWand *wand,
%        const double radius,const double sigma,const double intensity_sigma,
%        const double spatial_sigma)
%
%  A description of each parameter follows:
%
%    o wand: the magick wand.
%
%    o radius: the radius of the Gaussian, in pixels, not counting the center
%      pixel.
%
%    o sigma: the standard deviation of the , in pixels.
%
%    o intensity_sigma: sigma in the intensity space. A larger value means
%      that farther colors within the pixel neighborhood (see spatial_sigma)
%      will be mixed together, resulting in larger areas of semi-equal color.
%
%    o spatial_sigma: sigma in the coordinate space. A larger value means that
%      farther pixels influence each other as long as their colors are close
%      enough (see intensity_sigma ). When the neigborhood diameter is greater
%      than zero, it specifies the neighborhood size regardless of
%      spatial_sigma. Otherwise, the neigborhood diameter is proportional to
%      spatial_sigma.

%  adjusted to match the virtual canvas offsets of each layer. As such the
%  given offset is relative to the virtual canvas, and not the actual image.
%
%  Composition uses given x and y offsets, as the 'origin' location of the
%  source images virtual canvas (not the real image) allowing you to compose a
%  list of 'layer images' into the destiantioni images.  This makes it well
%  sutiable for directly composing 'Clears Frame Animations' or 'Coaleased
%  Animations' onto a static or other 'Coaleased Animation' destination image
%  list.  GIF disposal handling is not looked at.
%
%  Special case:- If one of the image sequences is the last image (just a
%  single image remaining), that image is repeatally composed with all the
%  images in the other image list.  Either the source or destination lists may
%  be the single image, for this situation.
%
%  In the case of a single destination image (or last image given), that image

%  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:

%        const DistortMethod method,const size_t number_arguments,

%
%  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.

%  MagickHoughLineImage() can be used in conjunction with any binary edge
%  extracted image (we recommend Canny) to identify lines in the image. The
%  algorithm accumulates counts for every white pixel for every possible
%  orientation (for angles from 0 to 179 in 1 degree increments) and distance
%  from the center of the image to the corner (in 1 px increments) and stores
%  the counts in an accumulator matrix of angle vs distance. The size of the
%  accumulator is 180x(diagonal/2). Next it searches this space for peaks in
%  counts and converts the locations of the peaks to slope and intercept in the
%  normal x,y input image space. Use the slope/intercepts to find the endpoints
%  clipped to the bounds of the image. The lines are then drawn. The counts are
%  a measure of the length of the lines.

%  MagickImportImagePixels() accepts pixel datand stores it in the image at the
%  location you specify.  The method returns MagickTrue on success otherwise
%  MagickFalse 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);

%
%  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 = alpha (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.
