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

◆ WCComplement() [1/4]

casacore::WCComplement::WCComplement ( )

Referenced by fromRecord(), operator=(), and WCComplement().

◆ WCComplement() [2/4]

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

Construct the complement of the given region.

◆ WCComplement() [3/4]

casacore::WCComplement::WCComplement ( const WCComplement & other )

Copy constructor (copy semantics).

References WCComplement().

◆ ~WCComplement()

virtual casacore::WCComplement::~WCComplement ( )

virtual

◆ WCComplement() [4/4]

casacore::WCComplement::WCComplement	(	Bool	takeOver,
		const Block< 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.

References casacore::WCCompound::regions().

Member Function Documentation

◆ className()

String casacore::WCComplement::className ( )

static

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

◆ cloneRegion()

virtual WCRegion * casacore::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 casacore::WCRegion.

◆ doToLCRegion()

virtual LCRegion * casacore::WCComplement::doToLCRegion	(	const CoordinateSystem &	cSys,
		const IPosition &	shape,
		const IPosition &	pixelAxesMap,
		const IPosition &	outOrder ) const

protectedvirtual

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

pixelAxesMap(i) gives the pixel axis in cSys of axes i in the axesDesc.

Implements casacore::WCRegion.

References casacore::shape().

◆ fromRecord()

WCComplement * casacore::WCComplement::fromRecord	(	const TableRecord &	,
		const String &	tableName )

static

Convert correct object from a record.

References WCComplement().

◆ operator=()

WCComplement & casacore::WCComplement::operator= ( const WCComplement & other )

Assignment (copy semantics).

References WCComplement().

◆ operator==()

virtual Bool casacore::WCComplement::operator== ( const WCRegion & other ) const

virtual

Comparison.

Reimplemented from casacore::WCCompound.

◆ toRecord()

virtual TableRecord casacore::WCComplement::toRecord ( const String & tableName ) const

virtual

Convert the (derived) object to a record.

Implements casacore::WCRegion.

◆ type()

virtual String casacore::WCComplement::type ( ) const

virtual

Get the region type.

Returns className()

Implements casacore::WCRegion.
