  NameDescription
Public propertySupported by Silverlight for Windows PhoneBoundsGets a Rect that specifies the axis-aligned bounding box of the Geometry. (Inherited from Geometry.)
Public propertySupported by Silverlight for Windows PhoneCenterGets or sets the center point of the EllipseGeometry.
Public propertySupported by Silverlight for Windows PhoneDispatcherGets the Dispatcher this object is associated with. (Inherited from DependencyObject.)

  NameDescription
Public methodSupported by Silverlight for Windows PhoneCheckAccessDetermines whether the calling thread has access to this object. (Inherited from DependencyObject.)
Public methodSupported by Silverlight for Windows PhoneClearValueClears the local value of a dependency property. (Inherited from DependencyObject.)
Public methodSupported by Silverlight for Windows PhoneEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodSupported by Silverlight for Windows PhoneFinalizeAllows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
Public methodSupported by Silverlight for Windows PhoneGetAnimationBaseValueReturns any base value established for a Silverlight dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject.)
Public methodSupported by Silverlight for Windows PhoneGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodSupported by Silverlight for Windows PhoneGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodSupported by Silverlight for Windows PhoneGetValueReturns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject.)
Protected methodSupported by Silverlight for Windows PhoneMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodSupported by Silverlight for Windows PhoneReadLocalValueReturns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject.)
Public methodSupported by Silverlight for Windows PhoneSetValueSets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject.)
Public methodSupported by Silverlight for Windows PhoneToStringReturns a string that represents the current object. (Inherited from Object.)

Geometries can be used individually or in combination to declare the data for a Path. For details on the relationship between Path and geometries, see Geometries.

FillRule is technically a property inherited from the base Geometry class, but setting it has no effect on an EllipseGeometry.

EllipseGeometry Compared to Ellipse

The Ellipse class has a Fill, Stroke, and other rendering properties that EllipseGeometry lacks.

The EllipseGeometry class simply defines the geometry of an ellipse, and cannot render itself. Because of its simplicity, it has a wider range of uses.

The following example shows how to create an ellipse using EllipseGeometry.


<Canvas>
  <Path Fill="Gold" Stroke="Black" StrokeThickness="1">
    <Path.Data>
      <EllipseGeometry Center="50,50" RadiusX="50" RadiusY="50" />
    </Path.Data>
  </Path>
</Canvas>


The following illustration shows the output from the example.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
