vtkTypeBool HandleBoundaries
Store vtkAlgorithm input/output information.
int RequestData(vtkInformation *request, vtkInformationVector **inputVector, vtkInformationVector *outputVector) override
This is called by the superclass.
virtual int RequestUpdateExtent(vtkInformation *, vtkInformationVector **, vtkInformationVector *)
Subclasses can reimplement this method to translate the update extent requests from each output port ...
int vtkTypeBool
Definition: vtkABI.h:69
Generic filter that has one input.
a simple class to control print indentation
Definition: vtkIndent.h:33
topologically and geometrically regular array of data
Definition: vtkImageData.h:39

Computes the gradient vector.
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.
~vtkImageGradient() override
Store zero or more vtkInformation instances.
static vtkAlgorithm * New()
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
