Detailed Description

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 parametrizes 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.

Member Function Documentation

operator()()

basegfx::B2DPolyPolygon slideshow::internal::ClippingFunctor::operator()	(	double	nValue,
		const ::basegfx::B2DSize &	rTargetSize
	)

Generate clip polygon.

Parameters

nValue	Value to generate the polygon for. Must be in the range [0,1].
rTargetSize	Size the clip polygon should cover. This is typically the size of the object the effect is applied on.
