And when you call getGeometry, that’s the polygon it returns. However, you can not set your own geometry. That is because there is no way to guarantee that the polygon geometry you set is actually an ellipse. So if you need to construct an ellipse, you need to do it by setting the input parameters mentioned earlier. The above is true even when IElement.getGeometry() is used to construct a GeoEllipse (above line 601). The inputs for other MA Geometries - GeoPolyline and GeoPolygon – are actually polyline and polygon geometries respectively. So this is the case only for GeoEllipse. In most use cases, you would anyways want to create Ellipse with center point, axes etc." */ GeoEllipse geoEllipse = new GeoEllipse(); geoEllipse.setAxisX(gEllipse.getAxisY()); geoEllipse.setAxisY(gEllipse.getAxisY());
