#include <itkImageConstIteratorWithIndex.h>
A base class for multi-dimensional iterators templated over image type that are designed to efficiently keep track of the iterator position.
ImageConstIteratorWithIndex is a templated class to represent a multi-dimensional iterator, and is templated over both the dimension and data type of the image.
ImageConstIteratorWithIndex is a base class for the "WithIndex" family of ITK image iterators, which are designed to efficiently keep track of the image index position of the iterator during increment and decrement operations. This iterator is a base class and provides only the basic construction and comparison operations. It does not provide mechanisms for moving the iterator. A subclass of ImageConstIteratorWithIndex must be used to move the iterator.
ImageConstIteratorWithIndex 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, ImageConstIteratorWithIndex holds a reference to the image over which it is traversing.
ImageConstIteratorWithIndex 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.
