Detailed Description

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

An iterator that walks a Bresenham line through an ND image with write access to pixels.

LineIterator 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.

* LineConstIterator<ImageType> it(image, I1, I2);
* while (!it.IsAtEnd())
* {
*    // visits at least 1 pixel
* }
*

Member Data Documentation

template<typename TImage>

const unsigned int itk::LineIterator< TImage >::ImageIteratorDimension = TImage::ImageDimension

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.
