This class implements basic functionality for color handling in itom. This class implements ARGB32 into itom. In openCV-mat this will be represented by an 4channel uint8-plane. The functions of this class are inspired by http://virjo.googlecode.com/svn/trunk/SFML_Windows/src/SFML/Graphics/Color.cpp, written by Laurent Gomila (laurent.gom@gmail.com) More...

Multiplication by a float32 grayFactor (alpha is unchanged).

| runtime_error | if grayFactor < 0 |
Multiplication by another Rgba32 value.
| All | channels are multiplied by each other and then divided by 255 (integer division leads to a ceil operation in any case) |
