Cv2GetMouseWheelDelta Method

Gets the mouse-wheel motion delta, when handling mouse-wheel events cv::EVENT_MOUSEWHEEL and cv::EVENT_MOUSEHWHEEL. For regular mice with a scroll-wheel, delta will be a multiple of 120. The value 120 corresponds to a one notch rotation of the wheel or the threshold for action to be taken and one such action should occur for each delta.Some high-precision mice with higher-resolution freely-rotating wheels may generate smaller values. For cv::EVENT_MOUSEWHEEL positive and negative values mean forward and backward scrolling, respectively.For cv::EVENT_MOUSEHWHEEL, where available, positive and negative values mean right and left scrolling, respectively.
