Detailed Description

Computes divergence of gradient.

vtkImageLaplacian computes the Laplacian (like a second derivative) of a scalar image. The operation is the same as taking the divergence after a gradient. Boundaries are handled, so the input is the same as the output. Dimensionality determines how the input regions are interpreted. (images, or volumes). The Dimensionality defaults to two.

Member Function Documentation

static vtkImageLaplacian* vtkImageLaplacian::New (  )  [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkAlgorithm.

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

Reimplemented from vtkThreadedImageAlgorithm.

static int vtkImageLaplacian::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.

virtual int vtkImageLaplacian::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.

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

Reimplemented from vtkThreadedImageAlgorithm.

void vtkImageLaplacian::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.

virtual void vtkImageLaplacian::SetDimensionality ( int   )  [virtual]

Determines how the input is interpreted (set of 2d slices ...)

virtual int vtkImageLaplacian::GetDimensionality (  )  [virtual]

Determines how the input is interpreted (set of 2d slices ...)

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

Reimplemented from vtkImageAlgorithm.

void vtkImageLaplacian::ThreadedRequestData ( vtkInformation request,
vtkInformationVector **  inputVector,
vtkInformationVector outputVector,
vtkImageData ***  inData,
vtkImageData **  outData,
int  extent[6],
int  threadId 
) [protected, virtual]

If the subclass does not define an Execute method, then the task will be broken up, multiple threads will be spawned, and each thread will call this method. It is public so that the thread functions can call this method.

Reimplemented from vtkThreadedImageAlgorithm.
