ImageProcessor
For 8-bit and 16-bit images, returns an array with one entry for each possible value that a pixel can have, from 0 to 255 (8-bit image) or 0-65535 (16-bit image). Thus, the array size is 256 or 65536, and the bin width in uncalibrated units is 1.
For RGB images, the brightness is evaluated using the color weights (which would result in a float value) and rounded to an int. This gives 256 bins. FloatProcessor.getHistogram is not implemented (returns null).
