### Specify background color when rotating an image using OpenCV in Python

I'm trying to rotate an image in Python using OpenCV with the following code:

import cv2

rows = img.shape[0]
cols = img.shape[1]

img_center = (cols / 2, rows / 2)
M = cv2.getRotationMatrix2D(img_center, 45, 1)

rotated_image = cv2.warpAffine(img, M, (cols, rows))


The code works as it should, but the background where the image is no longer visible turns black. I want the background to be white and I'm therefore wondering if it's possible to specify the color OpenCV should use for it when rotating.
