This example shows how to create a cubic Bezier curve. To create a cubic Bezier curve, use the <xref:System.Windows.Media.PathGeometry>, <xref:System.Windows.Media.PathFigure>, and <xref:System.Windows.Media.BezierSegment> classes. To display the resulting geometry, use a <xref:System.Windows.Shapes.Path> element, or use it with a <xref:System.Windows.Media.GeometryDrawing> or a <xref:System.Windows.Media.DrawingContext>. In the following examples, a cubic Bezier curve is drawn from (10, 100) to (300, 100). The curve has control points of (100, 0) and (200, 200).
