-class EllipsMarker from Graphic2d inherits VectorialMarker from Graphic2d
-
- ---Version:
-
- ---Purpose: The primitive EllipsMarker
- -- Every marker takes a reference point as an argument in
- -- its constructor. CircleMarker and EllipsMarker take
- -- another point as the center and PolylineMarker takes the
- -- first point of its list as its origin.
- -- The coordinates of the centre or origin point are offsets
- -- with respect to the reference point.

- ---Level: Public
- ---Purpose: Creates an ellipse marker with a reference point.
- -- The reference point is <aXPosition>, <aYPosition>.
- -- The center is <X>, <Y>.
- -- Angles are measured counterclockwise with 0 radian
- -- at 3 o'clock.
- -- Warning: Raises EllipsDefinitionError if the
- -- major radius or the minor radius is null.
