I implemented something that I call "pixel spy". It opens a second image
that is a copy of the region under the mouse pointer and that is updated
as you move the mouse. You can zoom in and out as for any other image in
imagej.
It is not an imagej plugin. But you could make one out of it easily.
It is quite clumpsy. To keep the zoom set by the user it maximizes the
pixel spy window and zooms in or out again. On slow computers you might
see this. It works fine enough for the application it was created for
but there is certainly a better way to do this. Besides I added
something to the method ImageWindow>>windowActivated to get informed
when the active window changes. If you know or find out how to this
without changing the imagej base code please tell me.
If you want to have a look at it, I can send you the source code.
