Detailed Description

template<class T>
class vigra::RGBPrime2XYZFunctor< T >

Convert non-linear (gamma corrected) R'G'B' into standardized tri-stimulus XYZ.

#include <vigra/colorconversions.hxx>
Namespace: vigra

The functor realizes the transformation

\[
    R'G'B' \Rightarrow RGB \Rightarrow XYZ
\]

See vigra::RGBPrime2RGBFunctor and vigra::RGB2XYZFunctor for a description of the two steps.

Traits defined:

FunctorTraits::isUnaryFunctor is true (VigraTrueType)
