Remarks

Use a PathFigure object to create composite shapes using QuadraticBezierSegment objects and other segments.

The QuadraticBezierSegment class does not contain a property for the starting point of the line. The starting point of the line is the end point of the previous segment, or the StartPoint of the PathFigure if no other segments exist.

Examples

The following example creates a PathGeometry with two PathFigure objects, each of which contains multiple PathSegment objects.

<Canvas>
  <Path Stroke="Black" StrokeThickness="1" >
    <Path.Data>
      <PathGeometry>
        <PathGeometry.Figures>
          <PathFigure StartPoint="10,50">
            <PathFigure.Segments>
              <BezierSegment Point1="100,0"
                Point2="200,200"
                Point3="300,100"/>
              <LineSegment Point="400,100" />
              <ArcSegment Size="50,50" RotationAngle="45"
                IsLargeArc="True" SweepDirection="Clockwise"
                Point="200,100"/>
            </PathFigure.Segments>
          </PathFigure>

          <PathFigure StartPoint="10,100">
            <PathFigure.Segments>
              <PolyLineSegment Points="50,100 50,150" />
              <QuadraticBezierSegment Point1="200,200" Point2="300,100"/>
            </PathFigure.Segments>
          </PathFigure>
        </PathGeometry.Figures>
      </PathGeometry>
    </Path.Data>
  </Path>
</Canvas>
