Ellipse

let ellipse = Ellipse(center:Point(x:155, y:200), radiusX:120, radiusY:55)                                                                                                                                                                                                                                                                          
canvas.render(ellipse)

Rotated Ellipse

let rotatedEllipse = Ellipse(center:Point(x:155, y:200), radiusX:120, radiusY:55, rotation (1.0/4.0)*Double.pi)
canvas.render(rotatedEllipse)

Partial Ellipse

let partialEllipse = Ellipse(center:Point(x:155, y:200), radiusX:120, radiusY:55, rotation:0.0, startAngle:0.0, endAngle:(3.0/2.0)*Double.pi)
canvas.render(partialEllipse)
