Intersection of two WPF geometries

I needed to determine the intersection point of a Rectangle and a Bezier curve. I found the following code here.

I've included the code below in case the link is lost in the future.

public static Point[] GetIntersectionPoints(Geometry g1, Geometry g2)
{
   Geometry og1 = g1.GetWidenedPathGeometry(new Pen(Brushes.Black, 1.0));
   Geometry og2 = g2.GetWidenedPathGeometry(new Pen(Brushes.Black, 1.0));

   CombinedGeometry cg = new CombinedGeometry(GeometryCombineMode.Intersect, og1, og2);
   PathGeometry pg = cg.GetFlattenedPathGeometry();
   Point[] result = new Point[pg.Figures.Count];

   for (int i = 0; i < pg.Figures.Count; i++)
   {
      Rect fig = new PathGeometry(new PathFigure[] { pg.Figures[i] }).Bounds;
      result[i] = new Point(fig.Left + fig.Width / 2.0, fig.Top + fig.Height / 2.0);
   }
   return result;
}
