		const Vector< Quantity > &	radii,
		const IPosition &	pixelAxes,
		const CoordinateSystem &	cSys,

	)

ellipsoid with axes parallel to coordinate axes

casacore::WCEllipsoid::WCEllipsoid	(	const Vector< Quantity > &	center,
		const Quantity &	radius,
		const IPosition &	pixelAxes,
		const CoordinateSystem &	cSys,

sphere.

pixelAxes must have the same base units and those pixels musb be square or an exception is thrown.

		const RegionType::AbsRelType	absRel = `RegionType::Abs`
	)

2-D ellipse.

The axes must have the same base units and those pixels must be square or an exception is thrown. theta is the angle between the pixelAxis0 and the major axis of the ellipse.

Bool casacore::WCEllipsoid::canExtend ( ) const

virtual

Can the region extend itself? By default it cannot.

Reimplemented from casacore::WCRegion.

static String casacore::WCEllipsoid::className ( )

static

WCRegion* casacore::WCEllipsoid::cloneRegion ( ) const

virtual

Clone a WCRegion object.

Implements casacore::WCRegion.

LCRegion* casacore::WCEllipsoid::doToLCRegion	(	const CoordinateSystem &	cSys,
		const IPosition &	shape,
		const IPosition &	pixelAxesMap,
		const IPosition &	extendAxes
	)		const

virtual

Convert to an LCRegion using the given coordinate system and shape.

pixelAxesMap(i) is the axis in cSys and shape for region axis i.
outOrder(i) is the axis in the output LCRegion for region axis i.
They always have the same length. If the region can extend itself, the length of pixelAxesMap and outOrder can be more than the dimensionality of the region. The latter axes in them are the extension axes.

Implements casacore::WCRegion.

static

WCEllipsoid& casacore::WCEllipsoid::operator= ( const WCEllipsoid & that )

Bool casacore::WCEllipsoid::operator== ( const WCRegion & other ) const

virtual

Comparison.

Reimplemented from casacore::WCRegion.

TableRecord casacore::WCEllipsoid::toRecord ( const String & tableName ) const

virtual

Convert the (derived) object to a record.

The record can be used to make the object persistent. The tableName argument can be used by derived classes (e.g. LCPagedMask) to put very large objects.

Implements casacore::WCRegion.

String casacore::WCEllipsoid::type ( ) const

virtual

Return region type.

Just returns the class name of the derived class.

Implements casacore::WCRegion.
