LineGeometry class

Represents the geometry of a line.

Inheritance

Object
  DependencyObject
    Geometry

Syntax


public sealed class LineGeometry : Geometry


<LineGeometry .../>

Members

The LineGeometry class has these types of members:

Constructors

The LineGeometry class has these constructors.

ConstructorDescription
LineGeometry Initializes a new instance of the LineGeometry class that has no length.

 

Methods

The LineGeometry 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 LineGeometry class has these properties.

PropertyAccess typeDescription

Bounds

Read-onlyGets a Rect that specifies the axis-aligned bounding box of the Geometry. (Inherited from Geometry)

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)

EndPoint

Read/writeGets or sets the end point of a line.

EndPointProperty

Read-onlyIdentifies the EndPoint dependency property.

StartPoint

Read/writeGets or sets the start point of the line.

StartPointProperty

Read-onlyIdentifies the StartPoint dependency property.

Transform

Read/writeGets or sets the Transform object applied to a Geometry. (Inherited from Geometry)

 

Examples

This example shows how to create and render a LineGeometry object. A Geometry object only defines the geometry of the object—it does not render anything directly—so the example uses a Path shape to render the line. Because a line has no area, setting the Fill property of the Path would have no effect; instead, only the Stroke and StrokeThickness properties are specified.


<Canvas Width="200" Height="200">
    <Path Stroke="Black" StrokeThickness="4" >
        <Path.Data>
            <LineGeometry StartPoint="10,20" EndPoint="100,130" />
        </Path.Data>
    </Path>
</Canvas>
