Examples

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

<Canvas>
    <Path Stroke="Black" StrokeThickness="4" >
        <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>

Remarks

This class is relevant for setting the vector data for either a Path or a PathIcon.

Rather than creating an instance or an object element, you can also define a QuadraticBezierSegment as part of a vector within the string for a Move and draw commands syntax.

Constructors

QuadraticBezierSegment()

Initializes a new instance of the QuadraticBezierSegment class.

Properties

Dispatcher	Gets the CoreDispatcher that this object is associated with. The CoreDispatcher represents a facility that can access the DependencyObject on the UI thread even if the code is initiated by a non-UI thread. (Inherited from DependencyObject)
Point1	Gets or sets the control point of the curve.
Point1Property	Identifies the Point1  dependency property.
Point2	Gets or sets the end Point of this QuadraticBezierSegment.
Point2Property	Identifies the Point2  dependency property.

Methods

ClearValue(DependencyProperty)	Clears the local value of a dependency property. (Inherited from DependencyObject)
GetAnimationBaseValue(DependencyProperty)	Returns any base value established for a dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject)
GetValue(DependencyProperty)	Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject)
ReadLocalValue(DependencyProperty)	Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject)
RegisterPropertyChangedCallback(DependencyProperty, DependencyPropertyChangedCallback)	Registers a notification function for listening to changes to a specific DependencyProperty on this DependencyObject instance. (Inherited from DependencyObject)
SetValue(DependencyProperty, Object)	Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject)
UnregisterPropertyChangedCallback(DependencyProperty, Int64)	Cancels a change notification that was previously registered by calling RegisterPropertyChangedCallback. (Inherited from DependencyObject)
