RectangleGeometry RectangleGeometry RectangleGeometry RectangleGeometry Class


Describes a two-dimensional rectangular geometry.

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.

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


RectangleGeometry() RectangleGeometry() RectangleGeometry() RectangleGeometry()

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

public : RectangleGeometry()
RectangleGeometry() const;
public RectangleGeometry()
Public Sub New()


Bounds Bounds Bounds Bounds

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

(Inherited from Geometry)

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.

Rect Rect Rect Rect

Gets or sets the dimensions of the rectangle.

public : Rect Rect { get; set; }
Rect Rect(); void Rect(Rect rect);
public Rect Rect { get; set; }
Public ReadWrite Property Rect As Rect
<RectangleGeometry Rect="x,y,width,height"/>
<RectangleGeometry Rect="x y width height"/>
Rect Rect

The Rect structure that describes the position and size of the rectangle. The default is null.

RectProperty RectProperty RectProperty RectProperty

Identifies the Rect dependency property.

public : static DependencyProperty RectProperty { get; }
static DependencyProperty RectProperty();
public static DependencyProperty RectProperty { get; }
Public Static ReadOnly Property RectProperty As DependencyProperty
DependencyProperty DependencyProperty

The identifier for the Rect dependency property.

StandardFlatteningTolerance StandardFlatteningTolerance StandardFlatteningTolerance StandardFlatteningTolerance

Gets the standard tolerance used for polygonal approximation.

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.

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.

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.
