| class CCameraViewFinder : public CBase |
CCamera view finder base class is used to provide features common to both client view finders and direct view finders.
This class is not intended for stand alone use. One of the derived class shall be used instead. Features of this class will automatically be used when either direct view finder or client based view finder are created by clients.
If the class methods leave, the output type parameter value is not guaranteed to be valid.
