Detailed Description

template<class TPixel, class TContainer>
class itk::SliceIterator< TPixel, TContainer >

A flexible iterator for itk containers(i.e. itk::Neighborhood) that support pixel access through operator[].

SliceIterator allows iteration along a std::slice through the container. A slice is a construct that defines a starting position, stride length (distance between adjacent elements), and a length.

Any container with operator[] is supported. Because it uses this interface the iterator is only as efficient as the implementation of a container's operator[] method.

SliceIterator itk::SliceIterator< TPixel, TContainer >::operator++ ( int  )

inline

Increments the iterator.
