#include <itkImageConstIterator.h>
A multi-dimensional image iterator templated over image type.
ImageConstIterator is a templated class to represent a multi-dimensional iterator. ImageConstIterator is templated over the type of the image to be iterated over.
ImageConstIterator is a base class for all the image iterators. It provides the basic construction and comparison operations. However, it does not provide mechanisms for moving the iterator. A subclass of ImageConstIterator must be used to move the iterator.
ImageConstIterator 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, ImageConstIterator holds a reference to the image over which it is traversing.
ImageConstIterator 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.
