Remarks

Use this class to create a series of connected lines in a PathFigure.

Examples

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

The following illustration shows the shape created by this example.

<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" />
