- Method Detail
  - getZoomIncrement
```
double getZoomIncrement()
```
    Returns:
    
    The zoom increment used when zooming in/out.
  - getMaxZoom
```
double getMaxZoom()
```
    Returns:
    
    The maximal level of zooming allowed.
  - getMinZoom
```
double getMinZoom()
```
    Returns:
    
    The minimal level of zooming allowed.
  - getZoom
```
double getZoom()
```
    Returns:
    
    The zoom level.
  - setZoom
```
void setZoom(double x,
             double y,
             double zoomingLevel)
```
    Zooms in the zoomable object.
    
    Parameters:
    
    zoomingLevel - The zooming level.
    
    x - The X-coordinate of the location to zoom.
    
    y - The Y-coordinate of the location to zoom.
  - getZoomedPoint
```
Point2D getZoomedPoint(double x,
                       double y)
```
    Transforms the given point in a point which coordinates have been modified to take account of the zoom level.
    
    Parameters:
    
    x - The X-coordinate of the point to modify.
    
    y - The Y-coordinate of the point to modify.
    
    Returns:
    
    The transformed point.
  - getZoomedPoint
```
Point2D getZoomedPoint(Point pt)
```
    Transforms the given point in a point which coordinates have been modified to take account of the zoom level.
    
    Parameters:
    
    pt - The point to transform.
    
    Returns:
    
    The transformed point. Returns (0,0) if the given point is null.
