Detailed Description

template<class TImage, class TPath>
class itk::PathIterator< TImage, TPath >

PathIterator iterates (traces) over a path through an image.

This iterator visits only those indices of the image which are overlapped by the path. All indicies are visited in path order. If a path crosses itself at an index, that index of the image will be visited twice. This class add write-access to the functionality of the PathConstIterator.

template<class TImage , class TPath >
void itk::PathConstIterator< TImage, TPath >::GoToBegin (  )  [inherited]

Move an iterator to the beginning of the path. If the starting and ending indicies of the path are coincident, then move to the 2'nd index of the path, since the 1'st index will be visited later as the last index. However, if m_VisitStartIndexAsLastIndexIfClosed is false, then GoToBegin() will always move to the 1'st index.

template<class TImage , class TPath >
bool itk::PathConstIterator< TImage, TPath >::IsAtEnd ( void   )  [inline, inherited]

Is the iterator at the end of the path? Note that for a closed path, it may be possible to increment back to the start of the path.

Definition at line 166 of file itkPathConstIterator.h.

template<class TImage , class TPath >
void itk::PathConstIterator< TImage, TPath >::operator++ (  )  [inherited]

Walk forward along the path to the next index in the image.

template<class TImage , class TPath >
Self& itk::PathIterator< TImage, TPath >::operator= ( const Self it  ) 

operator= is provided to make sure the handles to the image and path are properly reference counted.

Reimplemented from itk::PathConstIterator< TImage, TPath >.

template<class TImage , class TPath >
void itk::PathIterator< TImage, TPath >::Set ( const PixelType value  )  [inline]

Set the pixel value

template<class TImage , class TPath >
PixelType& itk::PathIterator< TImage, TPath >::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.

Definition at line 124 of file itkPathIterator.h.

template<class TImage , class TPath >
virtual void itk::PathConstIterator< TImage, TPath >::VisitStartIndexAsLastIndexIfClosed ( bool  flag  )  [inline, virtual, inherited]

Should GoToBegin() initially skip the first index of a closed path so that the first index will only be visited once--at the end of the path? If set to false, then GoToBegin() will always move to the 1'st index. The constructor presets m_VisitStartIndexAsLastIndexIfClosed to true.

const unsigned int itk::PathIterator< TImage, TPath >::ImageIteratorDimension = TImage::ImageDimension [static]

Dimension of the image 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.
