Python：IOError: image file is truncated 的解決辦法

代碼以下：

#coding:utf-8
from PIL import Image
import pytesseract
def test():
    im = Image.open(r"pic.gif")
    vcode = pytesseract.image_to_string(im)
    print vcode

執行以上代碼進行簡單驗證碼識別的時候會拋出一個異常：

Traceback (most recent call last):
  File "D:\test\vcode.py", line 15, in <module>
    main()
  File "D:\test\vcode.py", line 9, in main
    test()
  File "D:\test\test.py", line 8, in test
    vcode = pytesseract.image_to_string(im)
  File "build\bdist.win32\egg\pytesseract\pytesseract.py", line 143, in image_to_string
  File "D:\Program Files (x86)\Python\Python27\lib\site-packages\PIL\Image.py", line 1749, in split
    self.load()
  File "D:\Program Files (x86)\Python\Python27\lib\site-packages\PIL\ImageFile.py", line 232, in load
    "(%d bytes not processed)" % len(b))
IOError: image file is truncated (5 bytes not processed)

解決辦法是，再添加以下2句代碼：

from PIL import ImageFile
ImageFile.LOAD_TRUNCATED_IMAGES = True

最終，完整的代碼以下：

#coding:utf-8
from PIL import Image
import pytesseract
from PIL import ImageFile
ImageFile.LOAD_TRUNCATED_IMAGES = True
def test():
    im = Image.open(r"pic.gif")
    vcode = pytesseract.image_to_string(im)
    print vcode
