QuadraticBezierSegment Class
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Creates a quadratic Bezier curve between two points in a PathFigure.
System.Windows::DependencyObject
System.Windows.Media::PathSegment
System.Windows.Media::QuadraticBezierSegment
Assembly: System.Windows (in System.Windows.dll)
XMLNS for XAML: Not mapped to an xmlns.
The QuadraticBezierSegment type exposes the following members.
| Name | Description | |
|---|---|---|
 | QuadraticBezierSegment | Initializes a new instance of the QuadraticBezierSegment class. |
| Name | Description | |
|---|---|---|
 | Dispatcher | Gets the Dispatcher this object is associated with. (Inherited from DependencyObject.) |
| Point1 | Gets or sets the control point of the curve. |
| Point2 | Gets or sets the end Point of this QuadraticBezierSegment. |
| Name | Description | |
|---|---|---|
| CheckAccess | Determines whether the calling thread has access to this object. (Inherited from DependencyObject.) |
| ClearValue | Clears the local value of a dependency property. (Inherited from DependencyObject.) |
| Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) |
| GetAnimationBaseValue | Returns any base value established for a Windows Phone dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject.) |
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| GetValue | Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| ReadLocalValue | Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject.) |
| SetValue | Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| Name | Description | |
|---|---|---|
  | Point1Property | Identifies the Point1 dependency property. |
| Point2Property | Identifies the Point2 dependency property. |
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.
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>
The following illustration shows the shape created by this example.
