Rotated EllipseΒΆ

Learning targets

  • Define an ellipse and rotate it

The Ellipse definition in layout.jcm produces an ellipse with semi-major-axis lengths as specified in RadiusX and RadiusY. As default, the major axis are aligned in xy-directions. We rotate the ellipse by 20^{\circ} by setting the angle parameter Alpha.
