Detailed Description

template<class 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 Function Documentation

template<class TImage >
virtual const char* itk::LineIterator< TImage >::GetNameOfClass ( ) const
virtual

Run-time type information (and related methods).

Reimplemented from itk::LineConstIterator< TImage >.

template<class TImage >
Self& itk::LineIterator< TImage >::operator= ( const Self it)

operator= is provided to make sure the handle to the image is properly reference counted.

template<class TImage >
void itk::LineIterator< TImage >::Set ( const PixelType value)
inline

Set the pixel value

Definition at line 89 of file itkLineIterator.h.

template<class TImage >
const PixelType& itk::LineIterator< TImage >::Value ( void  )
inline

Return a reference to the pixel. This method will provide the fastest access to pixel data, but it will NOT support ImageAdaptors.

Member Data Documentation

template<class 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.
