I’ve been experimenting with an implementation of a radio dial in a window (to be displayed through an antique radio window). I have the circular dial image that would normally be a round plastic disc inside the radio. I can use cv2 to rotate the dial on the screen, but if I show the entire image, then I have to mount the display in the radio with the top half showing. I’d like to display it as a semicircle at the bottom of an OpenCV window.
I can’t figure out how to place the circular image at the bottom of the window and rotate it around the midpoint of the bottom of the screen. When I try making the screen half as large as the circle and setting the center at the bottom, the screen just resizes and shows the entire circle again.
Help?
