Detailed Description

Stretch length 1 axes in an LCRegion along straight lines.

Intended use:

Public interface

Prerequisite

Synopsis

The LCStretch class is a specialization of class LCRegion. It makes it possible to stretch a LCRegion along straight lines to other dimensions. E.g. a circle in the xy-plane can be stretched 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-)stretch matches the dimensionality of the lattice.

Constructor & Destructor Documentation

casacore::LCStretch::LCStretch ( )
casacore::LCStretch::LCStretch ( const LCRegion region,
const IPosition stretchAxes,
const LCBox stretchBox 
)

Stretch the given region along axes as given by stretchAxes from the bottom left corner (blc) to the top right corner (trc) as given by stretchBox.

The axes to be stretched need to have length 1 in the original region. Every kind of box (absolute, relative, fractional, unspecified) can be used to define the stretch blc and trc. The dimensionality of the LCStretch region is the same as the dimensionality of the original region.
The second version takes over the pointer when the switch is true.

const LCRegion region,
const IPosition stretchAxes,
const LCBox stretchBox
