# Ellipse

trait Ellipse extends EllipseBased with ShapeCentred

The Ellipse trait can either be implemented as an Ellipse class or as a Circle. Which also fulfills the Ellipse interface. The factory methods in the Ellipse companion object return [Ellipse]].

Companion:
object
trait Shape
trait Fillable
trait Drawable
trait GeomElem
class Object
trait Matchable
class Any
