Detailed Description

Make the intersection of 2 or more regions.

Intended use:

Public interface

Prerequisite

Synopsis

The LCRegionMulti class is a specialization of class LCRegion. It makes it possible to extend a LCRegion along straight lines to other dimensions. E.g. a circle in the xy-plane can be extended to a cylinder in the xyz-space. includes the intersection border. It can only be used for a lattice of any dimensionality as long as the dimensionality of the (hyper-)intersection matches the dimensionality of the lattice.

The center of the intersection must be inside the lattice

◆ LCRegionMulti() [4/6]

casacore::LCRegionMulti::LCRegionMulti ( Bool  takeOver,
const PtrBlock< const LCRegion * > &  regions

casacore::LCRegionMulti::LCRegionMulti ( const LCRegion region,
const IPosition latticeShape 
)
protected

Construct from lattice shape and region pointer, which is taken over.

Primarily meant for LCExtension.
