How to: Create a Cubic Bezier Curve

This example shows how to create a cubic Bezier curve. To create a cubic Bezier curve, use the PathGeometry, PathFigure, and BezierSegment classes. To display the resulting geometry, use a Path element, or use it with a GeometryDrawing or a 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).

[xaml]

In Extensible Application Markup Language (XAML), you may use abbreviated markup syntax to describe a path.

<Path Stroke="Black" StrokeThickness="1"  
  Data="M 10,100 C 100,0 200,200 300,100" />

[xaml]

In XAML, you can also draw a cubic Bezier curve using object tags. The following is equivalent to the previous XAML example.

<Path Stroke="Black" StrokeThickness="1">
  <Path.Data>
    <PathGeometry>
      <PathGeometry.Figures>
        <PathFigureCollection>
          <PathFigure StartPoint="10,100">
            <PathFigure.Segments>
              <PathSegmentCollection>
                <BezierSegment Point1="100,0" Point2="200,200" Point3="300,100" />
              </PathSegmentCollection>
            </PathFigure.Segments>
          </PathFigure>
        </PathFigureCollection>
      </PathGeometry.Figures>
    </PathGeometry>
  </Path.Data>
</Path>
