QuadraticBezierSegment class

Creates a quadratic Bezier curve between two points in a PathFigure.

Inheritance

Object
  DependencyObject
    PathSegment
      QuadraticBezierSegment

Syntax


public sealed class QuadraticBezierSegment : PathSegment


<QuadraticBezierSegment .../>

Members

The QuadraticBezierSegment class has these types of members:

Constructors

The QuadraticBezierSegment class has these constructors.

ConstructorDescription
QuadraticBezierSegment Initializes a new instance of the QuadraticBezierSegment class.

 

Methods

The QuadraticBezierSegment class has these methods. It also inherits methods from the Object class.

MethodDescription
ClearValue Clears the local value of a dependency property. (Inherited from DependencyObject)
GetAnimationBaseValue Returns any base value established for a dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject)
GetValue Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject)
ReadLocalValue Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject)
RegisterPropertyChangedCallback Registers an instance-specific property value for a property-changed notification that comes from the core property system. (Inherited from DependencyObject)
SetValue Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject)
UnregisterPropertyChangedCallback Cancels a change notification that was previously registered by calling RegisterPropertyChangedCallback. (Inherited from DependencyObject)

 

Properties

The QuadraticBezierSegment class has these properties.

PropertyAccess typeDescription

Dispatcher

Read-onlyGets the CoreDispatcher that this object is associated with. The CoreDispatcher represents a facility that can access the DependencyObject on the UI thread even if the code is initiated by a non-UI thread. (Inherited from DependencyObject)

Point1

Read/writeGets or sets the control point of the curve.

Point1Property

Read-onlyIdentifies the Point1 dependency property.

Point2

Read/writeGets or sets the end Point of this QuadraticBezierSegment.

Point2Property

Read-onlyIdentifies the Point2 dependency property.

 

Remarks

This class is relevant for setting the vector data for either a Path or a PathIcon.

Rather than creating an instance or an object element, you can also define a QuadraticBezierSegment as part of a vector within the string for a Move and draw commands syntax.

Examples

This example creates a PathGeometry with two PathFigure objects, each of which contains multiple PathSegment objects.


<Canvas>
    <Path Stroke="Black" StrokeThickness="4" >
        <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>
