求助代码报错'NoneType' object is not subscriptable

from PIL import Image, ImageDraw, ImageFont
import cv2
import os

def draw(pic):
    img = cv2.imread('pic/' + pic)
    img = img[:, :, (2, 1, 0)]

    blank = Image.new("RGB", ), len(img)], "white")
    drawObj = ImageDraw.Draw(blank)

    n = 10

    font = ImageFont.truetype('C:/Windows/Fonts/Microsoft YaHei UI/msyhbd.ttc', size = n - 1)

    for i in range(0, len(img), n):
      for j in range(0, len(img), n):
            text = '武汉加油'
            drawObj.ink = img + img * 256 + img * 256 * 256
            drawObj.text(, text, font=font)
            print('完成处理——', i, j)

    blank.save('new/new_' + pic, 'jpeg')


filelist = os.listdir('pic')
for file in filelist:
    draw(file)


运行报错
