Detailed Description

place a prioritized hierarchy of labels in screen space

This class is deprecated and will be removed from VTK in a future release. Use vtkLabelPlacementMapper instead.

This should probably be a mapper unto itself (given that the polydata output could be large and will realistically always be iterated over exactly once before being tossed for the next frame of the render).

In any event, it takes as input one (or more, eventually) vtkLabelHierarchies that represent prioritized lists of labels sorted by their placement in space. As output, it provides vtkPolyData containing only VTK_QUAD cells, each representing a single label from the input. Each quadrilateral has cell data indicating what label in the input it corresponds to (via an array named "LabelId").
