LineGeometry Class

Namespace:

Windows.UI.Xaml.Media

Represents the geometry of a line.

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>

Constructors

LineGeometry()

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

Properties

Bounds	Gets a Rect that specifies the axis-aligned bounding box of the Geometry. (Inherited from Geometry)
Dispatcher	Gets 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	Gets or sets the end point of a line.
EndPointProperty	Identifies the EndPoint dependency property.
StartPoint	Gets or sets the start point of the line.
StartPointProperty	Identifies the StartPoint dependency property.
Transform	Gets or sets the Transform object applied to a Geometry. (Inherited from Geometry)

Methods

ClearValue(DependencyProperty)	Clears the local value of a dependency property. (Inherited from DependencyObject)
GetAnimationBaseValue(DependencyProperty)	Returns any base value established for a dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject)
GetValue(DependencyProperty)	Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject)
ReadLocalValue(DependencyProperty)	Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject)
RegisterPropertyChangedCallback(DependencyProperty, DependencyPropertyChangedCallback)	Registers a notification function for listening to changes to a specific DependencyProperty on this DependencyObject instance. (Inherited from DependencyObject)
SetValue(DependencyProperty, Object)	Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject)
UnregisterPropertyChangedCallback(DependencyProperty, Int64)	Cancels a change notification that was previously registered by calling RegisterPropertyChangedCallback. (Inherited from DependencyObject)
