Method Detail

translate

public void translate(int deltaX,
                      int deltaY)

clone

public Object clone()
             throws CloneNotSupportedException

Overrides:

clone in class Object

Throws:

CloneNotSupportedException

toString

public String toString()

Overrides:

toString in class Object

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)
