I installed PIL 1.1.7 using the executable for Python 2.7. But when I run this code :
我使用 Python 2.7 的可执行文件安装了 PIL 1.1.7。但是当我运行这段代码时：
import requests
from PIL import *
def main() :
target = "http://target/image.php" #returns binary data for a PNG.
cookies = {"mycookie1", "mycookie2"}
r = requests.get(target, cookies=cookies)
im = Image.open(r.content) #r.content contains binary data for the PNG.
print im
if __name__ == "__main__" :
main()
It gives the error :
它给出了错误：
Traceback (most recent call last):
File "D:\Programming\Python\code\eg_cc1.py", line 17, in <module>
main()
File "D:\Programming\Python\code\eg_cc1.py", line 13, in main
im = Image.open(r.content)

You need to explicitly import the Image module:
您需要显式导入 Image 模块：
>>> from PIL import *
>>> Image
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'Image' is not defined
>>> import PIL.Image
>>> Image
<module 'Image' from 'c:\Python27\lib\site-packages\PIL\Image.pyc'>
>>>
Or just
要不就
>>> import Image

Use
用
from PIL import Image
This way it will work, and your code will be forward-compatible with Pillow. On the other hand, import Imagewill notwork with Pillow.
这样它就可以工作，并且您的代码将与Pillow向前兼容。在另一方面，import Image将不与枕头工作。
The development of PIL has been stopped in mid 2011, without any official announcement or explication. Pillow is a fork of original PIL and is actively developed.
PIL的开发于2011年年中停止，没有任何官方公告或说明。Pillow 是原始 PIL 的一个分支，并且正在积极开发中。

If
如果
import Image
is not working. Try:
不管用。尝试：
from PIL import Image
There is compatibility issue with all the packages in PIL. Try downloading PIL package manually for the latest version. Actually worked with this in Python 3.2 Version, everything is working fine.
PIL 中的所有包都存在兼容性问题。尝试手动下载最新版本的 PIL 包。实际上在Python 3.2 版本中使用它，一切正常。
