An ellipse has the following properties in addition to those listed for RegionShape:

x and y coordinate
x-radius and y-radius
angle of rotation

Constructor & Destructor Documentation

casa::RSEllipse::RSEllipse	(	double	x,
		double	y,
		double	xRadius,
		double	yRadius,
		casacore::MDirection::Types	worldSystem,
		double	angle = `0`
	)

World Constructor.

x, y, xRadius, yRadius, and angle must all be 1) using the same world system as defined by worldSystem, and 2) in unit RegionShape::UNIT. Angle is counterclockwise, and angle 0 is the east vector.

casa::RSEllipse::RSEllipse	(	double	x,
		double	y,
		double	xRadius,
		double	yRadius,
		double	angle = `0`
	)

Pixel Constructor.

Angle in counterclockwise degrees.
