LinearZoomManager

All Implemented Interfaces:

it.unibo.alchemist.boundary.ui.api.SlideInputManager , it.unibo.alchemist.boundary.ui.api.ZoomManager
```
public final class LinearZoomManager
extends AbstractSlideInputManager implements ZoomManager
                    
```
A LinearZoomManager converts the sliding of any physical/virtual device/control into a zoom rate through a linear function. Zoom = amount of slides * rate.
