Detailed Description

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

Represent Red, Green, Blue cand Alpha component 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]

bool itk::FixedArray< TComponent , VLength >::operator== ( const FixedArray< TComponent, 4 > & r ) const

inherited

Operators == and != are used to compare whether two arrays are equal. Note that arrays are equal when the number of components (size) is the same, and each component value is equal.

Operator != compares different types of arrays.

reference itk::FixedArray< TComponent , VLength >::operator[] ( short index )

inlineinherited

Allow the FixedArray to be indexed normally. No bounds checking is done. The separate versions are a work-around for an integer conversion bug in Visual C++.
