BezierSegment Class
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Represents a cubic Bezier curve drawn between two points.
System.Windows::DependencyObject
System.Windows.Media::PathSegment
System.Windows.Media::BezierSegment
Assembly: System.Windows (in System.Windows.dll)
XMLNS for XAML: Not mapped to an xmlns.
The BezierSegment type exposes the following members.
| Name | Description | |
|---|---|---|
 | Dispatcher | Gets the Dispatcher this object is associated with. (Inherited from DependencyObject.) |
| Point1 | Gets or sets the first control point of the curve. |
| Point2 | Gets or sets the second control point of the curve. |
| Point3 | Gets or sets the end point of the curve. |
| 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. |
| Point3Property | Identifies the Point3 dependency property. |
Use a PathFigure object to store BezierSegment objects and other segments.
A cubic Bezier curve is defined by four points: a start point, an end point (Point3), and two control points (Point1 and Point2). The BezierSegment class does not contain a property for the starting point of the curve; it only defines the end point. The beginning point of the curve is the current point of the PathFigure to which the BezierSegment is added.
The two control points of a cubic Bezier curve behave like magnets, attracting portions of what would otherwise be a straight line toward themselves and producing a curve. The first control point, Point1, affects the beginning portion of the curve; the second control point, Point2, affects the ending portion of the curve. Note that the curve doesn't necessarily pass through either of the control points; each control point moves its portion of the line toward itself, but not through itself.
To specify a Bezier type segment with more control points, see PolyBezierSegment.
The following example uses a BezierSegment as one of the PathSegment items in a PathGeometry.
<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> </PathGeometry.Figures> </PathGeometry> </Path.Data> </Path> </Canvas>
