%
%  ConstituteImage() returns an image from the pixel data you supply.
%  The pixel data must be in scanline order top-to-bottom.  The data can be
%  char, short int, int, float, or double.  Float and double require the
%  pixels to be normalized [0..1], otherwise [0..QuantumRange].  For example, to
%  create a 640x480 image from unsigned red-green-blue character data, use:
%
%      image = ConstituteImage(640,480,"RGB",CharPixel,pixels,&exception);
%
%  The format of the ConstituteImage method is:
%
%      Image *ConstituteImage(const size_t columns,const size_t rows,
%        const char *map,const StorageType storage,const void *pixels,
%        ExceptionInfo *exception)
%
%  A description of each parameter follows:
%
%    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.
%      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, 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.
%
%    o exception: return any errors or warnings in this structure.
