Examples

This example shows how to create and render a RectangleGeometry object. The position and dimensions of the rectangle are defined by a Rect property value, provided as an attribute. The position is (50,50) and the height and width are both 25, which creates a square.

<Canvas>
    <Path Fill="LemonChiffon" Stroke="Red" StrokeThickness="3">
        <Path.Data>
            <RectangleGeometry Rect="50,50,25,25" />
        </Path.Data>
    </Path>
</Canvas>

Constructors

RectangleGeometry()

Initializes a new instance of the RectangleGeometry class and creates a rectangle with zero area.

Properties

Bounds	Gets a Rect that specifies the axis-aligned bounding box of the Geometry. (Inherited from Geometry)
Dispatcher	Always returns `null` in a Windows App SDK app. Use DispatcherQueue instead. (Inherited from DependencyObject)
DispatcherQueue	Gets the `DispatcherQueue` that this object is associated with. The `DispatcherQueue` 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)
Rect	Gets or sets the dimensions of the rectangle.
RectProperty	Identifies the Rect 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)
