Detailed Description

Multiple executes per update.

Date:

2001/10/11 13:37:46

Revision:

1.30

Thanks:

Thanks to C. Charles Law who developed this class.

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?

Member Function Documentation

virtual const char* vtkImageIterateFilter::GetClassName (    )  [virtual]

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkImageToImageFilter. Reimplemented in vtkImageCityBlockDistance, vtkImageDecomposeFilter, vtkImageEuclideanDistance, vtkImageFFT, vtkImageFourierCenter, vtkImageFourierFilter, vtkImageRFFT, and vtkImageSkeleton2D.

int vtkImageIterateFilter::IsTypeOf (  const char *    type )  [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 vtkImageToImageFilter. Reimplemented in vtkImageCityBlockDistance, vtkImageDecomposeFilter, vtkImageEuclideanDistance, vtkImageFFT, vtkImageFourierCenter, vtkImageFourierFilter, vtkImageRFFT, and vtkImageSkeleton2D.

virtual int vtkImageIterateFilter::IsA (  const char *    type )  [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 vtkImageToImageFilter. Reimplemented in vtkImageCityBlockDistance, vtkImageDecomposeFilter, vtkImageEuclideanDistance, vtkImageFFT, vtkImageFourierCenter, vtkImageFourierFilter, vtkImageRFFT, and vtkImageSkeleton2D.

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

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkImageToImageFilter. Reimplemented in vtkImageCityBlockDistance, vtkImageDecomposeFilter, vtkImageEuclideanDistance, vtkImageFFT, vtkImageFourierCenter, vtkImageFourierFilter, vtkImageRFFT, and vtkImageSkeleton2D.

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 vtkImageToImageFilter. Reimplemented in vtkImageDecomposeFilter, vtkImageEuclideanDistance, and vtkImageSkeleton2D.

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.

void vtkImageIterateFilter::ComputeInputUpdateExtents (  vtkDataObject *    output )  [virtual]

What is the input update extent that is required to produce the desired output? By default, the whole input is always required but this is overridden in many subclasses. Reimplemented from vtkImageToImageFilter.

void vtkImageIterateFilter::ComputeInputUpdateExtent (  int    inExt[6], int    outExt[6] )  [inline, virtual]

Reimplemented from vtkImageToImageFilter. Reimplemented in vtkImageCityBlockDistance, vtkImageEuclideanDistance, vtkImageFFT, vtkImageFourierCenter, vtkImageRFFT, and vtkImageSkeleton2D. Definition at line 76 of file vtkImageIterateFilter.h.

void vtkImageIterateFilter::ExecuteInformation (    )  [protected, virtual]

Reimplemented from vtkImageToImageFilter. Reimplemented in vtkImageEuclideanDistance, vtkImageFFT, and vtkImageRFFT. Referenced by vtkImageRFFT::ExecuteInformation(), vtkImageFFT::ExecuteInformation(), and vtkImageEuclideanDistance::ExecuteInformation().

virtual void vtkImageIterateFilter::ExecuteInformation (  vtkImageData *    inData, vtkImageData *    outData )  [protected, virtual]

Reimplemented from vtkImageToImageFilter. Reimplemented in vtkImageEuclideanDistance, vtkImageFFT, and vtkImageRFFT.

void vtkImageIterateFilter::ExecuteData (  vtkDataObject *    output )  [protected]

Reimplemented from vtkImageToImageFilter.

virtual void vtkImageIterateFilter::IterativeExecuteData (  vtkImageData *    in, vtkImageData *    out )  [protected, pure virtual]

Reimplemented in vtkImageCityBlockDistance, vtkImageEuclideanDistance, vtkImageFFT, vtkImageFourierCenter, vtkImageRFFT, and vtkImageSkeleton2D.

virtual void vtkImageIterateFilter::AllocateOutputScalars (  vtkImageData *    outData )  [protected, virtual]

Reimplemented in vtkImageCityBlockDistance, and vtkImageEuclideanDistance.

virtual void vtkImageIterateFilter::SetNumberOfIterations (  int    num )  [protected, virtual]

Reimplemented in vtkImageSkeleton2D.
