Draw on the preview from IMX327 camera on Raspberry Pi

Question 1

Is it possible to draw a rectangle directly on the image in the Preview script (python or c++)? The video feed is put directly to HDMI so third party libraries drawn rectangle is below the camera preview.

Question 2

I'm sorry. I don't know how to do that right now.

I will study the problem further.

Question 3

Is it possible to access pixels values before the preview? If so, it should be possible to modify some values to get a rectangle on the preview.
