Detailed Description

template<typename TImage>
class itk::ImageReverseConstIterator< TImage >

Multi-dimensional image iterator.

ImageReverseConstIterator is a templated class to represent a multi-dimensional iterator. ImageReverseConstIterator is templated over the dimension of the image and the data type of the image.

ImageReverseConstIterator is a base class for all the reverse image iterators. It provides the basic construction and comparison operations. However, it does not provide mechanisms for moving the iterator. A subclass of ImageReverseConstIterator must be used to move the iterator.

ImageReverseConstIterator is a multi-dimensional iterator, requiring more information be specified before the iterator can be used than conventional iterators. Whereas the std::vector::iterator from the STL only needs to be passed a pointer to establish the iterator, the multi-dimensional image iterator needs a pointer, the size of the buffer, the size of the region, the start index of the buffer, and the start index of the region. To gain access to this information, ImageReverseConstIterator holds a reference to the image over which it is traversing.

ImageReverseConstIterator assumes a particular layout of the image data. In particular, the data is arranged in a 1D array as if it were [][][][slice][row][col] with Index[0] = col, Index[1] = row, Index[2] = slice, etc.
