Is it possible to have background images and changes based on where the window is?

For example in this image:

I am not asking how to make my terminal transparent, I am asking for the terminal's background to use an image of my choosing and as I move the terminal around it will show other part of the background based on the coordinates of the window, as shown in this gif:

Why I am asking this is because if I terminal goes over a window, it will show it in its background like this:

And I don't want this. I want to see just the wallpaper. Was wondering if this was possible?

I know that you have this background option which seems to be for parralax effect when scrolling up and down the emulator but was wondering if I can only apply it to where the window is positioned?
