94 % ConstituteImage() returns an image from the pixel data you supply.
95 % The pixel data must be in scanline order top-to-bottom. The data can be
96 % char, short int, int, float, or double. Float and double require the
97 % pixels to be normalized [0..1], otherwise [0..QuantumRange]. For example, to
98 % create a 640x480 image from unsigned red-green-blue character data, use:
99 %
100 % image = ConstituteImage(640,480,"RGB",CharPixel,pixels,&exception);
101 %
102 % The format of the ConstituteImage method is:

104 % Image *ConstituteImage(const size_t columns,const size_t rows,
105 % const char *map,const StorageType storage,const void *pixels,
106 % ExceptionInfo *exception)
107 %
108 % A description of each parameter follows:
109 %
110 % o columns: width in pixels of the image.
111 %
112 % o rows: height in pixels of the image.
113 %
114 % o map: This string reflects the expected ordering of the pixel array.
115 % It can be any combination or order of R = red, G = green, B = blue,
116 % A = alpha (0 is transparent), O = opacity (0 is opaque), C = cyan,
117 % Y = yellow, M = magenta, K = black, I = intensity (for grayscale),
118 % P = pad.
119 %
120 % o storage: Define the data type of the pixels. Float and double types are
121 % expected to be normalized [0..1] otherwise [0..QuantumRange]. Choose
122 % from these types: CharPixel, DoublePixel, FloatPixel, IntegerPixel,
123 % LongPixel, QuantumPixel, or ShortPixel.
124 %
125 % o pixels: This array of values contain the pixel components as defined by
126 % map and type. You must preallocate this array where the expected
127 % length varies depending on the values of width, height, map, and type.
128 %
129 % o exception: return any errors or warnings in this structure.
