Properties

	Name	Description
	Bounds	Gets a Rect that specifies the axis-aligned bounding box of the Geometry. (Inherited from Geometry.)
	Dispatcher	Gets the Dispatcher this object is associated with. (Inherited from DependencyObject.)
	RadiusX	Gets or sets the x-radius of the ellipse that is used to round the corners of the rectangle.
	RadiusY	Gets or sets the y-radius of the ellipse that is used to round the corners of the rectangle.
	Rect	Gets or sets the dimensions of the rectangle.
	Transform	Gets or sets the Transform object applied to a Geometry. (Inherited from Geometry.)

Methods

	Name	Description
	CheckAccess	Determines whether the calling thread has access to this object. (Inherited from DependencyObject.)
	ClearValue	Clears the local value of a dependency property. (Inherited from DependencyObject.)
	Equals(Object)	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	GetAnimationBaseValue	Returns any base value established for a Silverlight dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	GetValue	Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ReadLocalValue	Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject.)
	SetValue	Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Examples

The following 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. The following illustration shows the output of the example.
