I want to create an interactive ellipse on an image in a gui and retrieve its poperties like semi-major axis,semi-minor axis, angle and centroid for the same. I am struck at this. Using imellipse, I am not able to get the centroid and the angle. I have to get these values in a structure and then generate a xml file of it. Thanks!

If you have a well-distributed set of points on the ellipse, you can use the attached file to fit the points. The output gives all the ellipse parameters that you mentioned.

See my attached demo which will draw ellipses at various angles.
