python - ImageChops.duplicate - python

Question

我正在尝试使用 PIL 模块中的 ImageChops.dulpicate 函数，但我收到一个我不明白的错误:

这是代码

import PIL
import Image
import ImageChops
import os

PathDemo4a='C:/Documents and Settings/Ariel/My Documents/My Dropbox/lecture/demo4a'
PathDemo4b='C:/Documents and Settings/Ariel/My Documents/My Dropbox/lecture/demo4b'
PathDemo4c='C:/Documents and Settings/Ariel/My Documents/My Dropbox/lecture/demo4c'
PathBlackBoard='C:/Documents and Settings/Ariel/My Documents/My Dropbox/lecture/BlackBoard.bmp'

Slides=os.listdir(PathDemo4a)

for slide in Slides:
    #BB=Image.open(PathBlackBoard)
    BB=ImageChops.duplicate(PathBlackBoard) #BB=BlackBoard

这是错误；

Traceback (most recent call last):
  File "<pyshell#4>", line 1, in <module>
    ImageChops.duplicate('c:/1.BMP')
  File "C:\Python26\lib\site-packages\PIL\ImageChops.py", line 57, in duplicate
    return image.copy()
AttributeError: 'str' object has no attribute 'copy'

任何帮助将不胜感激

您需要将 Image 对象而不是字符串传递给复制函数。像这样的东西:

img = Image.open(PathBlackBoard)
BB = ImageChops.duplicate(img)
