Detailed Description
QColorTransform is an instantiation of a transformation between color spaces. It can be applied on color and pixels to convert them from one color space to another.
Setting up a QColorTransform takes some preprocessing, so keeping around QColorTransforms that you need often is recommended, instead of generating them on the fly.
