QuadraticBezierSegment Class

This example shows how to create a quadratic Bezier curve. To create a quadratic Bezier curve, use the PathGeometry, PathFigure, and QuadraticBezierSegment classes.
In the following examples, a quadratic Bezier curve is drawn from (10,100) to (300,100). The curve has a control point of (200,200).
In Extensible Application Markup Language (XAML), you can use attribute syntax to describe a path.
<Path Stroke="Black" StrokeThickness="1" Data="M 10,100 Q 200,200 300,100" />
(Note that this attribute syntax actually creates a StreamGeometry, a lighter-weight version of a PathGeometry. For more information, see the Path Markup Syntax page.)
In XAML, you may also draw a quadratic Bezier curve using object element syntax. 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> <QuadraticBezierSegment Point1="200,200" Point2="300,100" /> </PathSegmentCollection> </PathFigure.Segments> </PathFigure> </PathFigureCollection> </PathGeometry.Figures> </PathGeometry> </Path.Data> </Path>
