ImageWindow Magnification

[Sullivan, Michael J (College of Med.)]

hay All. I'm writing a plugin that will open two copies of the same image
side by side on the screen -- one is to be an "original" and the other a
working image. Unfortunately, The images open at a magnification of 0.75
and I cannot position them without them overlaping. I've been searching for
a way to affect the ImageWindows magnification but can't seem to find the
access point.  Any Ideas would be appreciated. --- Mike

Have you looked at the ImageCanvas.(set/get)Magnification methods. These
can be accessed from the ImageWindow

Use run("In") and run("Out") to change the magnification and getZoom()
to find out what it is. In a plugin, use IJ.run("In"), IJ.run("Out")
and

     ImagePlus imp = IJ.getImage();
     ImageWindow win = imp.getWindow();
     double magnification = win.getCanvas().getMagnification();
