igds_type: igds_ellipse
This geometry type is stored in an IGDS type 15 element.
Ellipse features are point features, and only have a single coordinate. This point serves as the center of the ellipse. Additional attributes specify the rotation, major axis, and minor axis of the ellipse.
The primary ellipse axis is not necessarily the longest axis, but rather the one whose orientation is specified by the rotation value.
Note: Tip: The ArcStroker transformer can be used to convert an ellipse to a polygon. This is useful for storing ellipses in systems that do not support them directly.
