`ZoomEvent(Object source, long when, int modifiers, GestureHandler handler, MouseEvent pe, float zoom, float delta, float scale)`

Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`float`	`getDelta()`	Delta to last zoom value lies within [-1..1].
`float`	`getScale()`	Returns the scale used to determine the `zoom` and hence it's `delta` value, which semantics depends on the `pointer type's` `MouseEvent.PointerClass`.
`float`	`getZoom()`	Zoom value lies within [0..2], with 1 as 1:1.
`String`	`toString()`

```
- Method Detail
  - getZoom
```
public final float getZoom()
```
    Zoom value lies within [0..2], with 1 as 1:1.
  - getDelta
```
public final float getDelta()
```
    Delta to last zoom value lies within [-1..1].
  - getScale
```
public final float getScale()
```
    Returns the scale used to determine the zoom and hence it's delta value, which semantics depends on the pointer type's MouseEvent.PointerClass.
    For MouseEvent.PointerClass.Offscreen, the scale is usually 1.0f and denominates an abstract value without association to a physical value.
    
    For MouseEvent.PointerClass.Onscreen, the scale varies and denominates the divisor of the distance the finger[s] have moved on the screen. Hence scale * delta reproduces the screen distance in pixels the finger[s] have moved.
