Method Detail
- clone
```
public Object clone()
             throws CloneNotSupportedException
```
  Overrides:
  
  clone in class Object
  
  Throws:
  
  CloneNotSupportedException
- setPixelMagnificationRatio
```
public void setPixelMagnificationRatio(double pixelMagnificationRatio)
```
  Change the selection to use the specified magnification ratio. Turns off fitToWindow if previously selected, since we have requested explicit magnification
  
  Parameters:
  
  pixelMagnificationRatio - the magnification factor of display pixels relative to the image pixels (i.e., 1.0 means 1 display pixel per 1 image pixel)
- toString
```
public String toString()
```
  Overrides:
  
  toString in class Object
- translate
```
public void translate(int deltaX,
                      int deltaY)
