Member Function Documentation

operator()()

basegfx::B2DPolyPolygon slideshow::internal::SweepWipe::operator() ( double  t )

overridevirtual

Retrieve the poly-polygon for value t.

Parameters

t	Current parameter value to retrieve the corresponding poly-polygon for. Permissible values for t must be in the range [0,1].

Returns

a poly-polygon corresponding to the given parameter value. The poly-polygon is interpreted as living in the unit rectangle (i.e. [0,1]x[0,1]), but is not necessarily constrained to completely lie in this area (this very much depends on the actual effect to be generated). Although, from a performance perspective, it currently is advantageous to try to keep the poly-polygon within these bounds (at least if there are no hard reasons not to do so), because then reversion or out transformations are potentially faster to compute (see the TransitionInfo::meReverseMethod member in transitionfactory.cxx). Furthermore, if one of the polygon modifications involve subtraction (also see TransitionInfo::meReverseMethod), all generated polygons should be oriented clock-wise (i.e. traversing the polygon vertices with increasing vertex index should generate a clock-wise movement).

Implements slideshow::internal::ParametricPolyPolygon.
