如何在这个Python meme生成器中添加Stroke？

from PIL import Image, ImageDraw, ImageFont

image = Image.open('meme.jpg')

draw = ImageDraw.Draw(image)
font = ImageFont.truetype('arial.ttf', size=40)

text = "Hello, World!"
x = 10
y = 10

# Stroke文本
draw.text((x-2, y), text, font=font, fill='black')
draw.text((x+2, y), text, font=font, fill='black')
draw.text((x, y-2), text, font=font, fill='black')
draw.text((x, y+2), text, font=font, fill='black')

# 实际文本
draw.text((x, y), text, font=font, fill='white')

image.save('meme_with_stroke.jpg')
image.show()
