## Detailed Description

### template<class From, class To = From>
class vigra::RGB2RGBPrimeFunctor< From, To >

Convert linear (raw) RGB into non-linear (gamma corrected) R'G'B'.

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

The functor realizes the transformation

By default, . This default can be overridden in the constructor. If both source and target colors components are stored as `unsigned char`, a look-up-table will be used to speed up the transformation.

Traits defined:

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

## Member Typedef Documentation

typedef TinyVector<From, 3> argument_type

| the functor's argument type

typedef NumericTraits<To>::RealPromote component_type

| the result component's promote type

typedef RGBValue<To> result_type

| the functor's result type

typedef RGBValue<To> value_type

Deprecated:
  use argument_type and result_type
