Detailed Description

template<class T, class TContainer>
class itk::NthElementPixelAccessor< T, TContainer >

Give access to the N-th of a Container type.

This class is intended to be used as parameter of an ImageAdaptor to make a Container appears as being of scalar type T, showing only the N-th component.

This class is templated over the container type. Any container type that provides a method: operator[]( unsigned int ) can be used here, for example: itkPoint, itkVector, itkVectorContainer, and std::vector.

For performance, no bound checking is performed during access to the n-th element.
