如何使用Python检查存储为URL的图像的透明度？

pip install pillow

from PIL import Image
from io import BytesIO
import requests

def check_transparency(url):
    response = requests.get(url)
    image = Image.open(BytesIO(response.content))
    
    # 判断图像是否包含透明度
    if image.mode in ('RGBA', 'LA') or (image.mode == 'P' and 'transparency' in image.info):
        return True
    else:
        return False

# 示例用法
url = "https://example.com/image.png"
result = check_transparency(url)
print(result)
