#include "vigra/colorconversions.hxx"
Namespace: vigra
According to ITU-R Recommendation BT.709, the functor realizes the transformation
By default,
. This default can be overridden in the constructor. X, Y, and Z are always positive and reach their maximum for white. The white point is obtained by transforming RGB(255, 255, 255). It corresponds to the D65 illuminant. Y represents the luminance ("brightness") of the color.
Traits defined:
the functor's argument type
the result's component type
the functor's result type
default constructor. The maximum value for each RGB component defaults to 255.
