Remarks

Each PathGeometry object defines a collection of PathFigure objects. Each of the PathFigure objects is composed of one or more PathSegment objects, such as ArcSegment and LineSegment, which actually define their shape.

The filled area of the PathGeometry is defined by taking all of the contained PathFigure objects that have their IsFilled property set to true and applying the FillRule to determine the enclosed area.
