| % 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. |
