Detailed Description

Class to convert a region to a boolean node.

Prerequisite

• Lattice
• LatticeExprNode
• LELInterface

Etymology

This derived LEL letter class handles a region as a boolean lattice.

Synopsis

This class makes it possible to handle a region as a true boolean lattice without the need to apply the region to an image. It means that it is only possible if the region has absolute lattice coordinates.

A description of the implementation details of the LEL classes can be found in Note 216

Motivation

It is useful to be able to handle a mask as a boolean lattice.
