To create an instance of class vtkAnnotationLayersAlgorithm, simply invoke its constructor as follows
obj = vtkAnnotationLayersAlgorithm
obj
is an instance of the vtkAnnotationLayersAlgorithm class.
string = obj.GetClassName ()
int = obj.IsA (string name)
vtkAnnotationLayersAlgorithm = obj.NewInstance ()
vtkAnnotationLayersAlgorithm = obj.SafeDownCast (vtkObject o)
vtkAnnotationLayers = obj.GetOutput ()
- Get the output data object for a port on this algorithm.
vtkAnnotationLayers = obj.GetOutput (int index)
- Get the output data object for a port on this algorithm.
obj.SetInput (vtkDataObject obj)
- Set an input of this algorithm. You should not override these
methods because they are not the only way to connect a pipeline.
Note that these methods support old-style pipeline connections.
When writing new code you should use the more general
vtkAlgorithm::SetInputConnection(). These methods transform the
input index to the input port index, not an index of a connection
within a single port.
obj.SetInput (int index, vtkDataObject obj)
- Set an input of this algorithm. You should not override these
methods because they are not the only way to connect a pipeline.
Note that these methods support old-style pipeline connections.
When writing new code you should use the more general
vtkAlgorithm::SetInputConnection(). These methods transform the
