#include <itkNumericTraitsRGBAPixel.h>

Detailed Description

template<typename T>
class itk::NumericTraits< RGBAPixel< T > >

Define numeric traits for RGBAPixel.

Template Parameters

T	Component type of RBGAPixel

We provide here a generic implementation based on creating types of RGBAPixel whose components are the types of the NumericTraits from the original RGBAPixel components. This implementation require support for partial specializations, since it is based on the concept that: NumericTraits<RGBAPixel< T > > is defined piecewise by RGBAPixel< NumericTraits< T > >
