This class provides a base class for objects that define shapes.
Syntax
class IXRGeometry : public IXRDependencyObject
Inheritance Hierarchy
IXRGeometry
Methods
In addition to the methods inherited from IXRDependencyObject, this class contains the following methods.

Description |
|---|---|
Retrieves the bounding box of the current object. |
|
Retrieves the IXRTransform derived object that affects the current object. |
|
Applies an IXRTransform derived object to the current object. |
Thread Safety
Members of this class are thread-safe if you previously called IXRApplication::CreateHostFromXaml and supplied it with an XRWindowCreateParams structure that has AllowsMultipleThreadAccess set to true.
Remarks
You can use IXRGeometry objects to clip regions and to define geometry for rendering two-dimensional graphic data as a path.
IXREllipseGeometry, IXRLineGeometry, and IXRRectangleGeometry are simple geometries that specify the geometrical shape as one element with basic coordinate or dimension properties. IXRGeometryGroup uses a collection of IXRGeometry objects to define a complex geometry. IXRPathGeometry uses a collection of IXRPathFigure objects to define a complex geometry.
When you create a class instance, use an IXRGeometryPtr smart pointer instead of a raw interface pointer. For more information, see XRPtr<Interface>.
You can also define an IXRGeometry object in Microsoft Silverlight 3 XAML. For information about the differences between XAML in XAML for Windows Embedded and Silverlight 3, see Differences Between Microsoft Silverlight 3 and XAML for Windows Embedded. For more information about how to define this element in the source XAML for your application, see the Geometry Class on MSDN.
IXRGeometry Compared to IXRShape
The IXRShape class and the classes that derive from it have rendering properties that IXRGeometry and its derived classes lack. IXRShape derives from IXRFrameworkElement and therefore can render itself. You can use its derived classes as content in any element that supports IXRUIElement children.
The geometry classes define the geometry of graphic elements and are used to define a path.
