To create an instance of class vtkImageFFT, simply invoke its constructor as follows
obj = vtkImageFFT
obj
is an instance of the vtkImageFFT class.
string = obj.GetClassName ()
int = obj.IsA (string name)
vtkImageFFT = obj.NewInstance ()
vtkImageFFT = obj.SafeDownCast (vtkObject o)
int = obj.SplitExtent (int splitExt[6], int startExt[6], int num, int total)
- Used internally for streaming and threads.
Splits output update extent into num pieces.
This method needs to be called num times. Results must not overlap for
consistent starting extent. Subclass can override this method.
This method returns the number of pieces resulting from a
successful split. This can be from 1 to "total".
If 1 is returned, the extent cannot be split.
