Convert TEllipse into TGraph


I have a TEllipse, for which I would like to get something like the list of points which form ellipse line to make a corresponding TGraph. Or, if it is possible, simply to convert somehow TEllipse into TGraph.
Is this possible?

TEllipse defines the ellipse by the box containing it. Then, internally, the points necessary to draw the ellipse are computed according to the ellipse equation. These points are not exposed, because they are simple to retrieve using the ellipse equation: … properties

Thank you
