A ERectangle object is fully defined knowing its nominal position (given by the coordinates of its center), its nominal size, its rotation angle and its outline tolerance. By default, the width and height values are 100, which means 100 pixels when the field of view is not calibrated and 100 "units" in case of a calibrated field of view.
