The default view will be the entire range each color can be in. And don't let the numberOfBins return anything else then 256 unless you have a very good reason for it.
About the views: a view is a zoom combined with a start level: the entire range of a channel is 0.0 - 1.0: this is the position. Combined with a zoom, we can calculate what part of a channel will fall in a bin. This gives us an interface to that the views that is not dependent of the actual colorspace of the histogram. The 'size' value is the size, again from 0.0 to 1.0 of the displayed range.
For comfort of the GUI, and because it is logical, channels are accessed in the order in which they are found in the channels() method. This is potentially different from the order in which they are internally ordered!

| ) | [pure virtual] |
Adds the values from the specified array of pixels to the bins -- does not reset anything.
| pixels | A pointer an array of pixeldata in the given colorspace | |
| selectionMask | a pointer to an array of bytes, where 0 is unselected and 1-255 is degree of selectedness. The array must be just as long as the array of pixels. | |
| nPixels | The number of pixels | |
| colorSpace | the colorspace that can decode the pixel data. |
