Constructor & Destructor Documentation

casa::AnnPolygon::AnnPolygon	(	const Vector< Quantity > &	xPositions,
		const Vector< Quantity > &	yPositions,
		const String &	dirRefFrameString,
		const CoordinateSystem &	csys,
		const IPosition &	imShape,
		const Quantity &	beginFreq,
		const Quantity &	endFreq,
		const String &	freqRefFrameString,
		const String &	dopplerString,
		const Quantity &	restfreq,
		const Vector< Stokes::StokesTypes >	stokes,
		const Bool	annotationOnly
	)

casa::AnnPolygon::AnnPolygon	(	const Vector< Quantity > &	xPositions,
		const Vector< Quantity > &	yPositions,
		const CoordinateSystem &	csys,
		const IPosition &	imShape,
		const Vector< Stokes::StokesTypes > &	stokes
	)

Simplified constructor.

all frequencies are used (these can be set after construction). xPositions and yPositions must be in the same frame as the csys direction coordinate. is a region (not just an annotation), although this value can be changed after construction.

Member Function Documentation

void casa::AnnPolygon::_init ( ) [private]

Reimplemented from casa::AnnRegion.

Vector<MDirection> casa::AnnPolygon::getCorners ( ) const

get the vertices converted to the coordinate system used at construction.
