void SetStandardDeviation(double a, double b, double c)
Store vtkAlgorithm input/output information.
void SetRadiusFactors(double f, double f2)
Sets/Gets the Radius Factors of the gaussian (no unit).
void SetStandardDeviation(double std)
Sets/Gets the Standard deviation of the gaussian in pixel units.
virtual int RequestUpdateExtent(vtkInformation *, vtkInformationVector **, vtkInformationVector *)
Subclasses can reimplement this method to translate the update extent requests from each output port ...
Performs a gaussian convolution.
Generic filter that has one input.
void SetRadiusFactor(double f)
Sets/Gets the Radius Factors of the gaussian (no unit).
a simple class to control print indentation

virtual void ThreadedRequestData(vtkInformation *request, vtkInformationVector **inputVector, vtkInformationVector *outputVector, vtkImageData ***inData, vtkImageData **outData, int extent[6], int threadId)
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.
Store zero or more vtkInformation instances.
