ID2D1EllipseGeometry interface

Represents an ellipse.

When to implement

Custom implementations are not supported.

Members

The ID2D1EllipseGeometry interface inherits from ID2D1Geometry. ID2D1EllipseGeometry also has these types of members:

Methods

The ID2D1EllipseGeometry interface has these methods.

MethodDescription
GetEllipse

Gets the D2D1_ELLIPSE structure that describes this ellipse geometry.

 

Remarks

Creating ID2D1EllipseGeometry Objects

To create an elipse geometry, use the ID2D1Factory::CreateEllipseGeometry method.

Direct2D geometries are immutable and device-independent resources created by ID2D1Factory. In general, you should create geometries once and retain them for the life of the application, or until they need to be modified. For more information about device-independent and device-dependent resources, see the Resources Overview.
