Set Magnification and Display Location of New Image

[Richard VanMetter]

I am image processing an existing (original) image.

I create a new ImagePlus for the results of the processing. I would like
to display the new ImagePlus at the same location and magnification as
the original image, which has been zoomed and panned prior to applying
the plugin.

Are there methods that would help me accomplish this? I have perused
methods for ImagePlus, ImageCanvas and ImageWindow without finding  
anything that appears to help.

Any suggestions would be appreciated.

Thanks

Rich

Probably the easiest solution would be to create a two image stack containing both the original and processed images. Here is a JavaScript example:

  imp = IJ.openImage("http://imagej.nih.gov/ij/images/boats.gif");
  imp.show();
  IJ.run("Set... ", "zoom=400");
  imp2 = imp.duplicate();
  IJ.run(imp2, "Find Edges", "slice");
  stack = imp.getStack();
  stack.addSlice("edges", imp2.getProcessor());
  imp.setStack(stack);
  imp.setSlice(2);
