Basically, I have an image (rectangle) and a polygon coordinates within it. I want to paint the outside of the polygon area.

vrx = np.array(([20,80],[60,50],[100.80],[80,120],[40,120]), np.int32)
img = cv2.fillPoly(img, [vrx], 255)

This code fills the color (white) with in Polygon, I need the inverse part of it. I want to mask white color for that image except the polygon part.
