You can use PIL module to draw contours on an image, Load your image eg (img = Image.open("myImage.png")) Pass you image in ImageDraw

import math
from PIL import Image, ImageDraw
from PIL import ImagePath 
  
side = 8
xy = [
    ((math.cos(th) + 1) * 90,
     (math.sin(th) + 1) * 60)
    for th in [i * (2 * math.pi) / side for i in range(side)]
    ]  
  
image = ImagePath.Path(xy).getbbox()  
size = list(map(int, map(math.ceil, image[2:])))
  
img = Image.new("RGB", size, "# f9f9f9") 
img1 = ImageDraw.Draw(img)  
img1.polygon(xy, fill ="# eeeeff", outline ="blue") 
  
img.show()
