Minimun ellipse bound that contain a point relative to the bound's origin [message #985654]

Hi all,
I've got a question, maybe someone has already encountred this problem.
I'm developing an editor with GEF. In my editor there are some nodes that have an ellipse as compartment.
My problem is calculating the minimun ellipse bound size so that all children object's are contained in the ellipse.
I've attached an image to better explain what i'm saying

index.php/fa/12342/0/

I need to get the minimun width and height of the ellipse, so that the point relative to the origin is on the ellipse perimeter.

If someone can help me i'll be great.

Tanks in advance
Mauro P.

Hi, this is a math question and I think you could find the answer in a mathematical tables or something.

What about the Ellipse.containsPoint()? This method could gives you a hint.
