Constructor & Destructor Documentation

DD::Image::PlanarReadInfo::PlanarReadInfo ( )

inline

The default constructor creates an invalid PlanarReadInfo object. Since the interface is read-only the created object cannot be subsequently modified to become valid. This should be used in appropriate situations to indicate that no valid image plane is possible (e.g., if the user has, via planarReadInfo(), requested channels that are not present in the source data).
