![]() The position and dimensions of the rectangle are defined by a Rect structure. The following example shows how to create and render a RectangleGeometry in a Path object: This property is backed by a BindableProperty object, which means that it can be the target of data bindings, and styled. The RectangleGeometry class defines the Rect property, of type Rect, which represents the dimensions of the rectangle. RectangleGeometryĪ rectangle geometry represents the geometry of a rectangle or square, and is defined with a Rect structure that specifies its relative position and its height and width. Setting the Fill property of a Path that renders a LineGeometry will have no effect, because a line has no interior. In this example, a LineGeometry is drawn from (10,20) to (100,130): The following example shows how to create and render a LineGeometry in a Path object: EndPoint, of type Point, which represents the end point of the line.StartPoint, of type Point, which represents the start point of the line.The LineGeometry class defines the following properties: This creates a red circle with a diameter of 100 device-independent units, whose interior is painted blue:Ī line geometry represents the geometry of a line, and is defined by specifying the start point of the line and the end point. In this example, the center of the EllipseGeometry is set to (50,50) and the x-radius and y-radius are both set to 50. The following example shows how to create and render an EllipseGeometry in a Path object: These properties are backed by BindableProperty objects, which means that they can be targets of data bindings, and styled. The default value of this property is 0.0. RadiusY, of type double, which represents the y-radius value of the geometry.RadiusX, of type double, which represents the x-radius value of the geometry.Center, of type Point, which represents the center point of the geometry.The EllipseGeometry class defines the following properties: EllipseGeometryĪn ellipse geometry represents the geometry or an ellipse or circle, and is defined by a center point, an x-radius, and a y-radius. These same shapes, as well as more complex shapes, can be created using a PathGeometry or by combining geometry objects together, but these classes provide a simpler approach for producing these basic geometric shapes. They are used to create basic geometric shapes, such as circles, lines, and rectangles. The simple geometry classes are EllipseGeometry, LineGeometry, and RectangleGeometry. The classes that derive from the Geometry class can be grouped into three categories: simple geometries, path geometries, and composite geometries. For more information, see Clip with a Geometry. ![]() When the Clip property is set to a Geometry object, only the area that is within the region of the Geometry will be visible. The VisualElement class has a Clip property, of type Geometry, that defines the outline of the contents of an element.You can render a Geometry by setting the Path.Data property to a Geometry object, and setting the Path object's Fill and Stroke properties. The Path class uses a Geometry to describe its contents.The following classes have properties that can be set to Geometry objects: While a Shape object is used to render 2D graphics, a Geometry object can be used to define the geometric region for 2D graphics, and define a region for clipping. While Shape objects are more readily usable than Geometry objects, Geometry objects are more versatile. Therefore, Shape objects can render themselves and participate in the layout system, while Geometry objects cannot. The Geometry class derives from the BindableObject class, while the Shape class derives from the View class. The Geometry and Shape classes seem similar, in that they both describe 2D shapes, but have an important difference. For more information, see RoundRectangleGeometry. There's also a RoundedRectangleGeometry class that derives from the GeometryGroup class.
