Detailed Description

Multiple executes per update.

vtkImageIterateFilter is a filter superclass that supports calling execute multiple times per update. The largest hack/open issue is that the input and output caches are temporarily changed to "fool" the subclasses. I believe the correct solution is to pass the in and out cache to the subclasses methods as arguments. Now the data is passes. Can the caches be passed, and data retrieved from the cache?

static int vtkImageIterateFilter::IsTypeOf ( const char * name ) [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkThreadedImageAlgorithm.

Reimplemented in vtkImageFourierFilter, vtkImageEuclideanDistance, vtkImageRFFT, vtkImageCityBlockDistance, vtkImageSeparableConvolution, vtkImageFFT, vtkImageSkeleton2D, vtkImageFourierCenter, and vtkImageDecomposeFilter.

virtual int vtkImageIterateFilter::IsA ( const char * name ) [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkThreadedImageAlgorithm.

Reimplemented in vtkImageFourierFilter, vtkImageEuclideanDistance, vtkImageRFFT, vtkImageCityBlockDistance, vtkImageSeparableConvolution, vtkImageFFT, vtkImageSkeleton2D, vtkImageFourierCenter, and vtkImageDecomposeFilter.

static vtkImageIterateFilter* vtkImageIterateFilter::SafeDownCast ( vtkObjectBase * o ) [static]

Reimplemented in vtkImageFourierFilter, vtkImageEuclideanDistance, vtkImageRFFT, vtkImageCityBlockDistance, vtkImageSeparableConvolution, vtkImageFFT, vtkImageSkeleton2D, vtkImageFourierCenter, and vtkImageDecomposeFilter.

void vtkImageIterateFilter::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)		`[virtual]`

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkThreadedImageAlgorithm.

Reimplemented in vtkImageSeparableConvolution, vtkImageEuclideanDistance, vtkImageSkeleton2D, and vtkImageDecomposeFilter.

virtual int vtkImageIterateFilter::GetIteration ( ) [virtual]

Get which iteration is current being performed. Normally the user will not access this method.

virtual int vtkImageIterateFilter::GetNumberOfIterations ( ) [virtual]

Get which iteration is current being performed. Normally the user will not access this method.

virtual int vtkImageIterateFilter::RequestUpdateExtent	(	vtkInformation *	,
		vtkInformationVector **	,
		vtkInformationVector *
	)		`[protected, virtual]`

Subclasses can reimplement this method to translate the update extent requests from each output port into update extent requests for the input connections.

Reimplemented from vtkImageAlgorithm.

virtual int vtkImageIterateFilter::RequestInformation	(	vtkInformation *	request,
		vtkInformationVector **	inputVector,
		vtkInformationVector *	outputVector
	)		`[protected, virtual]`

Subclasses can reimplement this method to collect information from their inputs and set information for their outputs.

Reimplemented from vtkImageAlgorithm.

		vtkInformationVector **	inputVector,
		vtkInformationVector *	outputVector
