Constructor & Destructor Documentation

casa::QtWCBox::QtWCBox ( )

casa::QtWCBox::QtWCBox	(	const Vector< Quantum< Double > > &	blc,
		const Vector< Quantum< Double > > &	trc,
		const CoordinateSystem &	cSys,
		const Vector< Int > &	absRel
	)

Construct from vectors of world coordinates defining the box corners.

It is assumed that the order of the values is in the order of the pixel axes in the given coordinate system.

casa::QtWCBox::QtWCBox	(	const Vector< Quantum< Double > > &	blc,
		const Vector< Quantum< Double > > &	trc,
		const IPosition &	pixelAxes,
		const CoordinateSystem &	cSys,
		const Vector< Int > &	absRel
	)

Construct from vectors of world coordinates defining the box corners.

You specify the pixel axis order of the world values.

casa::QtWCBox::QtWCBox	(	const LCRegion &	region,
		const CoordinateSystem &	cSys
	)

Construct from the bounding box of an LCRegion.

casa::QtWCBox::QtWCBox ( const QtWCBox & other )

Copy constructor (reference semantics [except for CoordinateSystem])

virtual casa::QtWCBox::~QtWCBox ( ) [virtual]

Destructor.

Member Function Documentation

virtual Bool casa::QtWCBox::canExtend ( ) const [virtual]

static String casa::QtWCBox::className ( ) [static]

Returns QtWCBox.

virtual WCRegion* casa::QtWCBox::cloneRegion ( ) const [virtual]

Clone a QtWCBox object.

Implements casa::WCRegion.

void casa::QtWCBox::convertPixel	(	Double &	pixel,
		const Quantum< Double > &	value,
		const Int	absRel,
