## Detailed Description

### template<class T>
class vigra::XYZ2LabFunctor< T >

Convert standardized tri-stimulus XYZ into perceptual uniform CIE L*a*b*.

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

The functor realizes the transformation

where is the reference white point. represents the lighness ("brightness") of the color, and code the chromaticity.

Traits defined:

`FunctorTraits::isUnaryFunctor` is true (`VigraTrueType`)

## Member Typedef Documentation

typedef TinyVector<component_type, 3> result_type

the functor's result type

typedef TinyVector<component_type, 3> value_type

Deprecated:
  use argument_type and result_type
