Detailed Description


template<class T>
class vigra::RGBPrime2LabFunctor< T >

Convert non-linear (gamma corrected) R'G'B' into perceptual uniform CIE L*a*b*.

#include "vigra/colorconversions.hxx"
Namespace: vigra

The functor realizes the transformation

See vigra::RGBPrime2RGBFunctor, vigra::RGB2XYZFunctor and vigra::XYZ2LabFunctor for a description of the three steps. The resulting color components will have the following bounds:

Traits defined:

FunctorTraits::isUnaryFunctor is true (VigraTrueType)
