Constructor & Destructor Documentation

template<class DType >
vtkImageIterator< DType >::vtkImageIterator ( )

Default empty constructor, useful only when creating an array of iterators You need to call Initialize afterward

template<class DType >
vtkImageIterator< DType >::vtkImageIterator ( vtkImageData id,
int ext 
)

Create an image iterator for a given image data and a given extent


Member Function Documentation

template<class DType >
void vtkImageIterator< DType >::Initialize ( vtkImageData id,
int ext 
)

Initialize the image iterator for a given image data, and given extent

template<class DType >
void vtkImageIterator< DType >::NextSpan ( )

Move the iterator to the next span

Reimplemented in vtkImageProgressIterator< DType >.

template<class DType >
SpanIterator vtkImageIterator< DType >::BeginSpan ( ) [inline]

Return an iterator (pointer) for the span

Definition at line 57 of file vtkImageIterator.h.

template<class DType >
SpanIterator vtkImageIterator< DType >::EndSpan ( ) [inline]

Return an iterator (pointer) for the end of the span

Definition at line 65 of file vtkImageIterator.h.

template<class DType >
int vtkImageIterator< DType >::IsAtEnd ( ) [inline]

Test if the end of the extent has been reached

Reimplemented in vtkImageProgressIterator< DType >.
