Base class for compound WCRegion objects.
Internal
WCCompound is the base class for world coordinate regions. It defines the functionality simply as conversion to an LCRegion. This is because you need an LCRegion to be able to access the pixels in a Lattice.
The conversion functions should be flexible in that the supplied CoordinateSystem does not have to be the same as that with which the derived class was constructed. This means that you can apply a WCCompound from one image to another, provided that operation has some meaning.

casa::WCCompound::WCCompound | ( | const ImageRegion & | region1, | |
const ImageRegion & | region2 | |||
) |
Construct from one or more image regions.
The image regions have to contain WCRegion objects, otherwise an exception is thrown.

casa::WCCompound::WCCompound | ( | const PtrBlock< const ImageRegion * > & | 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.
casa::WCCompound::WCCompound | ( | const WCCompound & | other | ) |
Copy constructor (copy semantics).

void casa::WCCompound::init | ( | Bool | takeOver | ) | [private] |
Check if the regions are correct.
If needed, make a copy of the region objects.
TableRecord casa::WCCompound::makeRecord | ( | const String & | tableName | ) | const [protected] |
Store the contributing regions in a record.
void casa::WCCompound::makeWCRegion | ( | const PtrBlock< const ImageRegion * > & | ) | [private] |
Check if the ImageRegion's contain WCRegion's and extract them.
