The IDLanROI object class represents a region of interest.

Note: The IDLan* naming convention is used for objects in the analysis domain.

Regions of interest are described as a set of vertices that may be connected to generate a path or a polygon, or may be treated as separate points. This object may be used as a source for analytical computations on regions. (For additional information about display of ROIs in Object Graphics, refer to the IDLgrROI object class.)
