public class SoScaleGestureRecognizer
extends SoGestureRecognizer
```
Scale (pinch) gesture recognizer. SoScaleGestureRecognizer analyses touch events and recognizes a scale (two finger pinch) gesture. It returns an SoScaleGestureEvent (pinch) event if this gesture is recognized. The scale event contains the scale factor between the current state and the initial one. This recognizer generates a BEGIN event, followed by DELTA events and finishing with an END event (SoGestureEvent.getGestureState()).
Note:
- In order to get touch events for the gesture recognizer(s) to recognize, the application must explicitly register a touch screen device (SoWinTouchScreen, SoQtTouchScreen, etc).
- In order to get gesture events, the application must explicitly register gesture recognizers with the touch screen device's touch manager (SoTouchManager).
