Detailed Description


template<class T>
class vigra::XYZ2RGBFunctor< T >

Convert standardized tri-stimulus XYZ into linear (raw) RGB.

#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. This is the inverse transform of vigra::RGB2XYZFunctor.

Traits defined:

FunctorTraits::isUnaryFunctor is true (VigraTrueType)


Member Typedef Documentation


typedef TinyVector<T, 3> argument_type

 

the functor's argument type. (Actually, the argument type is more general: V with arbitrary V. But this cannot be expressed in a typedef.)


typedef RGBValue<T> result_type

 

the functor's result type


typedef RGBValue<T> value_type

 

Deprecated:
use argument_type and result_type


Constructor & Destructor Documentation


XYZ2RGBFunctor   [inline]

 

default constructor. The maximum value for each RGB component defaults to 255.


XYZ2RGBFunctor component_type    max [inline]

 

constructor

  • max - the maximum value for each RGB component
