Hi

Is there a way to show same area between two images according to the
mouse moves? For example, using imtool to open two images, which are
the same area but with different gray levels. I'd like to use pixel
region to see gray levels at the same sub area. But I need to find the
center of the interest area by clicking the mouse twice at both
windows. Say, I move the mouse in the left window and the right window
will move accordingly.

linkaxes or linkprop, or adjust the callbacks for the ButtonDownFcn so
as to update the CurrentPosition for both axes.

I check the example in linkaxes. It is usually used in subplot. But
what I have are two images.
I use imtool for the two images. Can linkaxes or linkprop be used in
linking two images?
