Detailed Description

template<class DType>
class vtkImageStencilIterator< DType >

an image region iterator

This is an image iterator that can be used to iterate over a region of an image.

vtkImageData vtkImageStencilData vtkImageProgressIterator

Definition at line 35 of file vtkImageStencilIterator.h.


Constructor & Destructor Documentation

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

Default empty constructor, useful only when creating an array of iterators. Call Initialize() on each iterator before using.

template<class DType >
vtkImageStencilIterator< DType >::vtkImageStencilIterator ( vtkImageData image,
vtkImageStencilData stencil,
int  extent[6],
vtkAlgorithm algorithm = 0,
int  threadId = 0 
)

Create an iterator for an extent of an image. If a stencil is provided, it must have an extent at least as large as the desired extent.


Member Function Documentation

template<class DType >
void vtkImageStencilIterator< DType >::Initialize ( vtkImageData image,
vtkImageStencilData stencil,
int  extent[6] 
)

Initialize an iterator for an extent of the image. If a stencil is provided, it must have an extent at least as large as the desired extent.

template<class DType >
bool vtkImageStencilIterator< DType >::IsInStencil ( ) [inline]

Check if the iterator is within the stencilled region. This is updated when NextSpan() is called.

Definition at line 62 of file vtkImageStencilIterator.h.

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

Move the iterator to the start of the next span. A span is a contiguous region over which nothing but the X index changes.

template<class DType >
bool vtkImageStencilIterator< DType >::IsAtEnd ( ) [inline]

Test if the end of the extent has been reached

Definition at line 74 of file vtkImageStencilIterator.h.

template<class DType >
DType* vtkImageStencilIterator< DType >::BeginSpan ( ) [inline]

Return a pointer to the beginning of the current span.

Definition at line 82 of file vtkImageStencilIterator.h.

template<class DType >
DType* vtkImageStencilIterator< DType >::EndSpan ( ) [inline]

Return a pointer to the end of the current span.

Definition at line 90 of file vtkImageStencilIterator.h.

template<class DType >
void vtkImageStencilIterator< DType >::SetSpanState ( int  idX) [protected]

Set all the state variables for the stencil span that includes idX.

template<class DType >
void vtkImageStencilIterator< DType >::ReportProgress ( ) [protected]

Report the progress and do an abort check. This must be called every time that one row of the image is completed. Only called if Algorithm is not null.
