The PolyQuadraticBezierSegment type exposes the following members.
| Name | Description | |
|---|---|---|
 | PolyQuadraticBezierSegment | Initializes a new instance of the PolyQuadraticBezierSegment class. |
| Name | Description | |
|---|---|---|
 | Dispatcher | Gets the Dispatcher this object is associated with. (Inherited from DependencyObject.) |
| Points | Gets or sets the PointCollection that defines this PolyQuadraticBezierSegment object. |
| 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.) |
A QuadraticBezierSegment can have one control point, and an end point. A PolyQuadraticBezierSegment can have an essentially unlimited number of control points, with the values of these points and the end point given as the Points property value.
The following example creates two curves using a PolyQuadraticBezierSegment to specify the coordinates.
<Canvas> <Path Stroke="Black" StrokeThickness="1"> <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> </Path> </Canvas>
