Public interface
The WCIntersection class is a specialization of class WCCompound . It makes it possible to take the intersection of 2 or more image regions. Note that only world coordinate regions can be used in a compound, thus an LCSlicer object is not allowed in an intersection.
The intersection of regions is the collection of the pixels masked-on in all regions.
The regions in a intersection can have different axes and dimensionalities. The axes and dimensionality of a intersection are determined by the collection of all different axes in its regions. Each individual region will be auto-extended along the axes not being part of the region. E.g. one can define a WCBox with axis RA and another WCBox with axis DEC. The intersection will be 2-dim with axes RA and DEC. The first box will be auto-extended to cover the DEC axis, which results in a 2-dim box with its DEC axis the length of the image's DEC axis. Similarly the second box will be auto-extended to cover the RA axis.

casacore::WCIntersection::WCIntersection | ( | const ImageRegion & | region1, | |
const ImageRegion & | region2 | |||
) |
Construct the intersection of one or more image regions.
The image regions have to contain WCRegion objects, otherwise an exception is thrown.

casacore::WCIntersection::WCIntersection | ( | Bool | takeOver, | |
const PtrBlock< const WCRegion * > & | regions | |||
) |
Construct from multiple regions given as a Block.
When takeOver
is True, the destructor will delete the given regions. Otherwise a copy of the regions is made.
