Detailed Description

Make the complement of an image region.

Intended use:

Public interface

Prerequisite

WCCompound

Synopsis

The WCComplement class is a specialization of class WCCompound . It makes it possible to take the complement of the given region (which can be a simple WCBox, but also a complex compound region). Note that only world coordinate regions can be used in a compound, thus an LCSlicer object is not allowed in an intersection.

Note that a region consists of all its masked-on pixels inside the bounding box of the region. Thus the complement consists of all pixels outside the bounding box and all masked-off pixels inside the bounding box. So the complement of the complement of a region is the region itself.

Constructor & Destructor Documentation

casa::WCComplement::WCComplement ( )

casa::WCComplement::WCComplement ( const ImageRegion & region1 )

Construct the complement of the given region.

casa::WCComplement::WCComplement ( const WCComplement & other )

Copy constructor (copy semantics).

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

casa::WCComplement::WCComplement	(	Bool	takeOver,
		const PtrBlock< const WCRegion * > &	regions
	)

Construct from multiple regions.

When takeOver is True, the destructor will delete the given regions. Otherwise a copy of the regions is made.

Member Function Documentation

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

Get the class name (to store in the record).

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

Make a copy of the derived object.

cloneRegion needs to return a WCRegion * because the SGI compiler is smart enough to do the right thing.

Implements casa::WCRegion.

virtual LCRegion* casa::WCComplement::doToLCRegion	(	const CoordinateSystem &	cSys,
		const IPosition &	shape,
		const IPosition &	pixelAxesMap,
		const IPosition &	outOrder
	)		const `[protected, virtual]`
