Return Value

Type: Transform2DLinear

The transform that maps the unit circle arc to this ellipse.

Remarks

Gets a linear transform that maps the unit circle to this ellipse. The unit circle is a circle centered at (0,0) with a radius of one. The unit circle space is a child space of this shape. You can map positions in child space to the parent space using the returned transform. You can map from parent space to child space using the inverse transform.
