Examples

This example creates two curves using a PolyQuadraticBezierSegment to specify the coordinates.

<Canvas>
    <Path Stroke="Black" StrokeThickness="4">
        <Path.Data>
            <PathGeometry>
                <PathGeometry.Figures>
                    <PathFigureCollection>

                        <!-- The StartPoint specifies the starting point of the first curve. -->
                        <PathFigure StartPoint="10,100">
                            <PathFigure.Segments>
                                <PathSegmentCollection>

                                    <!-- The PolyQuadraticBezierSegment specifies two Bezier curves.
                  The first curve is from 10,100 (start point specified above)
                  to 300,100 with a control point of 200,200. The second curve
                  is from 200,200 (end of the last curve) to 30,400 with a 
                  control point of 0,200. -->
                                    <PolyQuadraticBezierSegment Points="200,200 300,100 0,200 30,400" />
                                </PathSegmentCollection>
                            </PathFigure.Segments>
                        </PathFigure>
                    </PathFigureCollection>
                </PathGeometry.Figures>
            </PathGeometry>
        </Path.Data>

Constructors

PolyQuadraticBezierSegment()

Initializes a new instance of the PolyQuadraticBezierSegment 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)
Points	Gets or sets the Point collection that defines this PolyQuadraticBezierSegment object.
PointsProperty	Identifies the Points  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)
