Detailed Description

Extend an LCRegion along straight lines to other dimensions

Intended use:

Public interface

Prerequisite

LCRegion

Synopsis

The LCExtension 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. It can be used for a lattice of any dimensionality as long as the dimensionality of the (hyper-)extension matches the dimensionality of the lattice.

Example

To Do

Extend along (slanted) cone lines

Constructor & Destructor Documentation

◆ LCExtension() [1/4]

casacore::LCExtension::LCExtension ( )

◆ LCExtension() [2/4]

casacore::LCExtension::LCExtension	(	const LCRegion &	region,
		const IPosition &	extendAxes,
		const LCBox &	extendBox
	)

Extend the given region along axes as given by extendAxes from the bottom left corner (blc) to the top right corner (trc) as given by extendBox.

Every kind of box (absolute, relative, fractional, unspecified) can be used to define the extension blc and trc. The sum of the dimensionality of the region and the extend box make up the dimensionality of the LCExtension region. Similarly the lattice shapes in region and box are combined.
The second version takes over the pointer when the switch is true.
