Need help getting function that returns a window's display image

Is there a function similar to Robot.getScreenCapture() that can return an image from a running program for the display it shows on the monitor? For example I've been trying to take a screenshot of a fullscreen game, but it returns black. I need something with that does the same thing as OBS recorder's gameCapture option, to get an image of a specific window.

edit: To clarify I want to take a screenshot of windows that are not part of this application
