The CogEllipse type exposes the following members.
Constructors
| Name | Description | |
|---|---|---|
| CogEllipse | Constructs a new instance of this class. | |
| CogEllipse(IntPtr) | Constructs a new instance of this class using com pointer. | |
| CogEllipse(CogEllipse) | Constructs a new instance of this class as a deep copy of the given instance. |
Methods
| Name | Description | |
|---|---|---|
| Clone | Returns a deep copy of this class instance. Derived classes that implement Clone should override this method; other clients who wish to clone this instance should call ICloneable.Clone. See also CogSerializer.DeepCopyObject | |
| Copy | Create a new shape that copies specified parameters. | |
| CopyBase | Copy a graphic and its derived parameters. | |
| CreateObjRef | Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.) | |
| CreateRLE | Create an RLE representation of this Region. | |
| Dispose | ||
| Dispose(Boolean) | ||
| DistanceToPoint | Shortest distance from a boundary of this shape to the given point. Points within closed shapes return a distance less than zero. | |

Remarks
Interface that describes an ellipse shape. You specify an ellipse with a center point, a rotation from the shape's x-axis that establishes the ellipse's x- and y-axes, a radius along the x-axis, and a radius along the y-axis.
The following picture shows the parts of the ellipse and the interactive handles available when GraphicDOFEnable is set to All.
Interactive HandleDescriptionRadii
Let you change the x- and y-radii.
Rotation
Lets you change the rotation of the ellipse which is used to establish the shape's x- and y-axes.
