Composite geometry objects can be created using a GeometryGroup. The GeometryGroup object creates an amalgamation of the Geometry objects it contains without combining their area. Any number of Geometry objects can be added to a GeometryGroup. This example uses a GeometryGroup to create a composite geometry.

    <Path Stroke="Black" StrokeThickness="4" Fill="#CCCCFF">

            <!-- Creates a composite shape from three geometries. -->
            <GeometryGroup FillRule="EvenOdd">
                <LineGeometry StartPoint="10,10" EndPoint="50,30" />
                <EllipseGeometry Center="40,70" RadiusX="30" RadiusY="30" />
                <RectangleGeometry Rect="30,55 100 30" />


GeometryGroup() GeometryGroup() GeometryGroup() GeometryGroup()

Initializes a new instance of the GeometryGroup class.


Bounds Bounds Bounds Bounds

Gets a Rect that specifies the axis-aligned bounding box of the Geometry.

(Inherited from Geometry)
Children Children Children Children

Gets or sets the GeometryCollection that contains the objects that define this GeometryGroup.

ChildrenProperty ChildrenProperty ChildrenProperty ChildrenProperty

Identifies the Children dependency property.

Dispatcher Dispatcher Dispatcher 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)
Empty Empty Empty Empty

Gets an empty geometry object.

FillRule FillRule FillRule FillRule

Gets or sets how the intersecting areas of the objects contained in this GeometryGroup are combined.

FillRuleProperty FillRuleProperty FillRuleProperty FillRuleProperty

Identifies the FillRule dependency property.

StandardFlatteningTolerance StandardFlatteningTolerance StandardFlatteningTolerance StandardFlatteningTolerance

Gets the standard tolerance used for polygonal approximation.

(Inherited from Geometry)
Transform Transform Transform Transform

Gets or sets the Transform object applied to a Geometry.

(Inherited from Geometry)
TransformProperty TransformProperty TransformProperty TransformProperty

Identifies the Transform dependency property.

ClearValue(DependencyProperty) ClearValue(DependencyProperty) ClearValue(DependencyProperty) ClearValue(DependencyProperty)

Clears the local value of a dependency property.

(Inherited from DependencyObject)
GetAnimationBaseValue(DependencyProperty) GetAnimationBaseValue(DependencyProperty) GetAnimationBaseValue(DependencyProperty) 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) GetValue(DependencyProperty) GetValue(DependencyProperty) GetValue(DependencyProperty)

Returns the current effective value of a dependency property from a DependencyObject.

(Inherited from DependencyObject)
ReadLocalValue(DependencyProperty) ReadLocalValue(DependencyProperty) ReadLocalValue(DependencyProperty) ReadLocalValue(DependencyProperty)

Returns the local value of a dependency property, if a local value is set.

(Inherited from DependencyObject)
RegisterPropertyChangedCallback(DependencyProperty,DependencyPropertyChangedCallback) RegisterPropertyChangedCallback(DependencyProperty,DependencyPropertyChangedCallback) RegisterPropertyChangedCallback(DependencyProperty,DependencyPropertyChangedCallback) 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) SetValue(DependencyProperty,Object) SetValue(DependencyProperty,Object) SetValue(DependencyProperty,Object)

Sets the local value of a dependency property on a DependencyObject.

(Inherited from DependencyObject)
UnregisterPropertyChangedCallback(DependencyProperty,Int64) UnregisterPropertyChangedCallback(DependencyProperty,Int64) UnregisterPropertyChangedCallback(DependencyProperty,Int64) UnregisterPropertyChangedCallback(DependencyProperty,Int64)

Cancels a change notification that was previously registered by calling RegisterPropertyChangedCallback.
