To create an instance of class vtkLabelHierarchyIterator, simply invoke its constructor as follows
obj = vtkLabelHierarchyIterator
obj
is an instance of the vtkLabelHierarchyIterator class.
string = obj.GetClassName ()
int = obj.IsA (string name)
vtkLabelHierarchyIterator = obj.NewInstance ()
vtkLabelHierarchyIterator = obj.SafeDownCast (vtkObject o)
obj.Begin (vtkIdTypeArray )
- Advance the iterator.
obj.Next ()
- Returns true if the iterator is at the end.
bool = obj.IsAtEnd ()
- Retrieves the current label location.
obj.GetPoint (double x[3])
- Retrieves the current label location.
obj.GetSize (double sz[2])
- Retrieves the current label size.
obj.GetBoundedSize (double sz[2])
- Retrieves the current label maximum width in world coordinates.
int = obj.GetType ()
- Retrieves the current label type.
double = obj.GetOrientation ()
- Retrieves the current label orientation.
vtkIdType = obj.GetLabelId ()
- Get the label hierarchy associated with the current label.
vtkLabelHierarchy = obj.GetHierarchy ()
- Get the label hierarchy associated with the current label.
obj.SetTraversedBounds (vtkPolyData )
- Sets a polydata to fill with geometry representing
the bounding boxes of the traversed octree nodes.
obj.BoxNode ()
- Add a representation to TraversedBounds for the current octree node.
This should be called by subclasses inside Next().
Does nothing if TraversedBounds is NULL.
obj.BoxAllNodes (vtkPolyData )
- Add a representation for all existing octree nodes to the specified polydata.
This is equivalent to setting TraversedBounds, iterating over the entire hierarchy,
and then resetting TraversedBounds to its original value.
obj.SetAllBounds (int )
- Set/get whether all nodes in the hierarchy should be added to the TraversedBounds
polydata or only those traversed.
When non-zero, all nodes will be added.
By default, AllBounds is 0.
int = obj.GetAllBounds ()
- Set/get whether all nodes in the hierarchy should be added to the TraversedBounds
polydata or only those traversed.
When non-zero, all nodes will be added.
By default, AllBounds is 0.
