Implementing Hardware ROI
For hardware ROI, the user defines the ROI on the device. The device returns only the
data in the specified ROI.
To implement hardware ROI, you must overload both the IAdaptor's getROI() and
setROI() member functions in your implementation of your adaptor class. By default, if
the IAdaptor object's getROI() member function is not overloaded, ROI configurations
will be handled in software by imaqkit::IEngine.
