The PolyQuadraticBezierSegment type exposes the following members.

  NameDescription
Public methodPolyQuadraticBezierSegmentInitializes a new instance of the PolyQuadraticBezierSegment class.
Top

  NameDescription
Public propertyDispatcherGets the Dispatcher this object is associated with. (Inherited from DependencyObject.)
Public propertyPointsGets or sets the PointCollection that defines this PolyQuadraticBezierSegment object.
Top

  NameDescription
Public methodCheckAccessDetermines whether the calling thread has access to this object. (Inherited from DependencyObject.)
Public methodClearValueClears the local value of a dependency property. (Inherited from DependencyObject.)
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetAnimationBaseValueReturns any base value established for a Windows Phone dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodGetValueReturns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodReadLocalValueReturns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject.)
Public methodSetValueSets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

  NameDescription
Public fieldStatic memberPointsPropertyIdentifies the Points dependency property.

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>
