Detailed Description

template<typename TComponent = unsigned short>
class itk::RGBAPixel< TComponent >

Represent Red, Green, Blue and Alpha components for color images.

This class is templated over the representation used for each component.

The following syntax for assigning an index is allowed/suggested:

RGBAPixel<float> pixel; pixel = 1.0f, 0.0f, .5f, .8;
RGBAPixel<char> pixelArray[2];
pixelArray[0] = 255, 255, 255, 230;
pixelArray[1] = 255, 255, 244, 255;

Since RGBAPixel is a subclass of Array, you can access its components as: pixel[0], pixel[1], pixel[2], pixel[3]
