## Detailed Description

### template<class From, class To = From>
class vigra::RGB2sRGBFunctor< From, To >

Convert linear (raw) RGB into standardized sRGB.

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

The sRGB color space is a slight improvement over the R'G'B' space. It is now a widely accepted international standard (IEC 61966-2.1) which is used by most consumer products (digital cameras, printers, and screens). The functor realizes the transformation

where C is any of the primaries R, G, and B. By default, (this default can be overridden in the constructor). If both source and target color 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
