Python：IOError: image file is truncated 的解决办法

代码如下：

#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

执行以上代码进行简单验证码识别的时候会抛出一个异常：

Traceback (most recent call last):
  File "D:	estvcode.py", line 15, in <module>
    main()
  File "D:	estvcode.py", line 9, in main
    test()
  File "D:	est	est.py", line 8, in test
    vcode = pytesseract.image_to_string(im)
  File "builddist.win32eggpytesseractpytesseract.py", line 143, in image_to_string
  File "D:Program Files (x86)PythonPython27libsite-packagesPILImage.py", line 1749, in split
    self.load()
  File "D:Program Files (x86)PythonPython27libsite-packagesPILImageFile.py", line 232, in load
    "(%d bytes not processed)" % len(b))
IOError: image file is truncated (5 bytes not processed)

解决办法是，再添加如下2句代码：

from PIL import ImageFile
ImageFile.LOAD_TRUNCATED_IMAGES = True

最终，完整的代码如下：

#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
