95 % ConstituteImage() returns an image from the pixel data you supply.
96 % The pixel data must be in scanline order top-to-bottom. The data can be
97 % char, short int, int, float, or double. Float and double require the
98 % pixels to be normalized [0..1], otherwise [0..QuantumRange]. For example, to
99 % create a 640x480 image from unsigned red-green-blue character data, use:
100 %
101 % image = ConstituteImage(640,480,"RGB",CharPixel,pixels,&exception);
102 %
103 % The format of the ConstituteImage method is:
104 %
105 % Image *ConstituteImage(const size_t columns,const size_t rows,
106 % const char *map,const StorageType storage,const void *pixels,
107 % ExceptionInfo *exception)
108 %
109 % A description of each parameter follows:
110 %
111 % o columns: width in pixels of the image.
112 %
113 % o rows: height in pixels of the image.
114 %
115 % o map: This string reflects the expected ordering of the pixel array.
116 % It can be any combination or order of R = red, G = green, B = blue,
117 % A = alpha (0 is transparent), O = opacity (0 is opaque), C = cyan,
118 % Y = yellow, M = magenta, K = black, I = intensity (for grayscale),
119 % P = pad.
120 %
121 % o storage: Define the data type of the pixels. Float and double types are
122 % expected to be normalized [0..1] otherwise [0..QuantumRange]. Choose
123 % from these types: CharPixel, DoublePixel, FloatPixel, IntegerPixel,
124 % LongPixel, QuantumPixel, or ShortPixel.
125 %
126 % o pixels: This array of values contain the pixel components as defined by
127 % map and type. You must preallocate this array where the expected
128 % length varies depending on the values of width, height, map, and type.
129 %
130 % o exception: return any errors or warnings in this structure.
