'Declaration Public NotInheritable Class BezierSegment _ Inherits PathSegment
public sealed class BezierSegment : PathSegment
The BezierSegment type exposes the following members.
|BezierSegment||Initializes a new instance of the BezierSegment class.|
|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.|
|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 Silverlight 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.)|
|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.
