%  AcquireImagePixels() returns an immutable pixel region. If the
%  region is successfully accessed, a pointer to it is returned, otherwise
%  NULL is returned. The returned pointer may point to a temporary working
%  copy of the pixels or it may point to the original pixels in memory.
%  Performance is maximized if the selected region is part of one row, or one
%  or more full rows, since there is opportunity to access the pixels in-place
%  (without a copy) if the image is in RAM, or in a memory-mapped file.  The
%  returned pointer should *never* be deallocated by the user.
%
%  Pixels accessed via the returned pointer represent a simple array of type
%  PixelPacket.  If the image type is CMYK or the storage class is PseudoClass,
%  call GetAuthenticIndexQueue() after invoking GetAuthenticPixels() to access
%  the black color component or to obtain the colormap indexes (of type
%  IndexPacket) corresponding to the region.
%
%  If you plan to modify the pixels, use GetAuthenticPixels() instead.
%
%  Note, the AcquireImagePixels() and GetAuthenticPixels() methods are not
%  thread-safe.  In a threaded environment, use GetCacheViewVirtualPixels() or
%  GetCacheViewAuthenticPixels() instead.

%  ColorFloodfill() changes the color value of any pixel that matches
%  target and is an immediate neighbor.  If the method FillToBorderMethod is
%  specified, the color value is changed for any neighbor pixel that does not
%  match the bordercolor member of image.
%
%  By default target must match a particular pixel color exactly.
%  However, in many cases two colors may differ by a small amount.  The
%  fuzz member of image defines how much tolerance is acceptable to
%  consider two colors as the same.  For example, set fuzz to 10 and the
%  color red at intensities of 100 and 102 respectively are now
%  interpreted as the same color for the purposes of the floodfill.
%
%  The format of the ColorFloodfillImage method is:
%
%      MagickBooleanType ColorFloodfillImage(Image *image,
%        const DrawInfo *draw_info,const PixelPacket target,
%        const ssize_t x_offset,const ssize_t y_offset,const PaintMethod method)
%
%  A description of each parameter follows:
%
%    o image: the image.
%
%    o draw_info: the draw info.
%
%    o target: the RGB value of the target color.
%
%    o x,y: the starting location of the operation.
%
%    o method: Choose either FloodfillMethod or FillToBorderMethod.

%  GetImagePixels() obtains a pixel region for read/write access. If the
%  region is successfully accessed, a pointer to a PixelPacket array
%  representing the region is returned, otherwise NULL is returned.
%
%  The returned pointer may point to a temporary working copy of the pixels
%  or it may point to the original pixels in memory. Performance is maximized
%  if the selected region is part of one row, or one or more full rows, since
%  then there is opportunity to access the pixels in-place (without a copy)
%  if the image is in RAM, or in a memory-mapped file. The returned pointer
%  should *never* be deallocated by the user.
%
%  Pixels accessed via the returned pointer represent a simple array of type
%  PixelPacket. If the image type is CMYK or if the storage class is
%  PseduoClass, call GetAuthenticIndexQueue() after invoking GetImagePixels()
%  to obtain the black color component or colormap indexes (of type IndexPacket)
%  corresponding to the region.  Once the PixelPacket (and/or IndexPacket)
%  array has been updated, the changes must be saved back to the underlying
%  image using SyncAuthenticPixels() or they may be lost.

%  target and is an immediate neighbor.  If the method FillToBorderMethod
%  is specified, the transparency value is changed for any neighbor pixel
%  that does not match the bordercolor member of image.
%
%  By default target must match a particular pixel transparency exactly.
%  However, in many cases two transparency values may differ by a
%  small amount.  The fuzz member of image defines how much tolerance is
%  acceptable to consider two transparency values as the same.  For example,

%  QuantizationError() measures the difference between the original and

%  error is computed by summing over all pixels in an image the distance
%  squared in RGB space between each reference pixel value and its quantized
%  value.  These values are computed:
%
%    o mean_error_per_pixel:  This value is the mean error for any single
%      pixel in the image.
%
%    o normalized_mean_square_error:  This value is the normalized mean
%      quantization error for any single pixel in the image.  This distance
%      measure is normalized to a range between 0 and 1.  It is independent
%      of the range of red, green, and blue values in the image.
%
%    o normalized_maximum_square_error:  Thsi value is the normalized
%      maximum quantization error for any single pixel in the image.  This

%  SetImagePixels() queues a mutable pixel region.
%  If the region is successfully intialized a pointer to a PixelPacket
%  array representing the region is returned, otherwise NULL is returned.
%  The returned pointer may point to a temporary working buffer for the
%  pixels or it may point to the final location of the pixels in memory.
%
%  Write-only access means that any existing pixel values corresponding to
%  the region are ignored.  This useful while the initial image is being
%  created from scratch, or if the existing pixel values are to be
%  completely replaced without need to refer to their pre-existing values.
%  The application is free to read and write the pixel buffer returned by
%  SetImagePixels() any way it pleases. SetImagePixels() does not initialize
%  the pixel array values. Initializing pixel array values is the
%  application's responsibility.
%
%  Performance is maximized if the selected region is part of one row, or
%  one or more full rows, since then there is opportunity to access the
%  pixels in-place (without a copy) if the image is in RAM, or in a
%  memory-mapped file. The returned pointer should *never* be deallocated
%  by the user.
%
%  Pixels accessed via the returned pointer represent a simple array of type
%  PixelPacket. If the image type is CMYK or the storage class is PseudoClass,
%  call GetAuthenticIndexQueue() after invoking GetAuthenticPixels() to obtain
%  the black color component or the colormap indexes (of type IndexPacket)
%  corresponding to the region.  Once the PixelPacket (and/or IndexPacket)
%  array has been updated, the changes must be saved back to the underlying
%  image using SyncAuthenticPixels() or they may be lost.

%  ZoomImage() creates a new image that is a scaled size of an existing one.
%  It allocates the memory necessary for the new Image structure and returns a
%  pointer to the new image.  The Point filter gives fast pixel replication,
%  Triangle is equivalent to bi-linear interpolation, and Mitchel giver slower,
%  very high-quality results.  See Graphic Gems III for details on this
%  algorithm.
%
%  The filter member of the Image structure specifies which image filter to
%  use. Blur specifies the blur factor where > 1 is blurry, < 1 is sharp.
