/** Generates the final clipping polygon.
|
|
|
|
This class serves as the functor, which generates the
|
|
final clipping polygon from a given ParametricPolyPolygon
|
|
and a TransitionInfo.
|
|
|
|
The ParametricPolyPolygon can be obtained from the
|
|
ParametricPolyPolygonFactory, see there.
|
|
|
|
The TransitionInfo further parameterizes the polygon
|
|
generated by the ParametricPolyPolygon, with common
|
|
modifications such as rotation, flipping, or change of
|
|
direction. This allows the ParametricPolyPolygonFactory to
|
|
provide only prototypical shapes, with the ClippingFunctor
|
|
further customizing the output.
