QuadraticBezierSegment Constructor (Point, Point, Boolean)

Initializes a new instance of the QuadraticBezierSegment class with the specified control point, end point, and Boolean indicating whether to stroke this QuadraticBezierSegment.

Namespace:  System.Windows.Media
Assembly:  PresentationCore (in PresentationCore.dll)

public QuadraticBezierSegment(
	Point point1,
	Point point2,
	bool isStroked
)

Parameters

point1
Type: System.Windows.Point

The control point of this QuadraticBezierSegment.

point2
Type: System.Windows.Point

The end point of this QuadraticBezierSegment.

isStroked
Type: System.Boolean

true if this QuadraticBezierSegment is to be stroked; otherwise, false.

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).

[xaml]

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" />

[xaml]

(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>
