#include <itkLineConstIterator.h>
An iterator that walks a Bresenham line through an ND image with read-only access to pixels.
LineConstIterator is an iterator that walks a Bresenham line through an image. The iterator is constructed similar to other image iterators, except instead of specifying a region to traverse, you specify two indices. The interval specified by the two indices is closed. So, a line iterator specified with the same start and end index will visit exactly one pixel.

void itk::LineConstIterator< TImage >::operator++ | ( | ) |
Walk forward along the line to the next index in the image.

operator= is provided to make sure the handle to the image is properly reference counted.
|
static |
Dimension of the image that the iterator walks. This constant is needed so that functions that are templated over image iterator type (as opposed to being templated over pixel type and dimension) can have compile time access to the dimension of the image that the iterator walks.
