python之使用 image.merge 合并 tif 图像

我正在尝试将 4 个 tif 合并在一起以形成 CMYK 图像。

这是我目前的代码:-

import Image 
 
m = "C:\Documents and Settings\dbigwood\Desktop\TEST\magnew.tif" 
c = "C:\Documents and Settings\dbigwood\Desktop\TEST\cyannew.tif" 
y = "C:\Documents and Settings\dbigwood\Desktop\TEST\yellownew.tif" 
k = "C:\Documents and Settings\dbigwood\Desktop\TEST\knew.tif" 
 
im = Image.merge("CMYK",(c,m,y,k)) 
 
im.save("C:\Documents and Settings\dbigwood\Desktop\TEST\AAA.tif") 

运行时报错

Traceback (most recent call last): 
  File "C:\Documents and Settings\dbigwood\Desktop\TEST\try5.py", line 18, in <module> 
    im = Image.merge("CMYK",(c,m,y,k)) 
  File "C:\Python26\ArcGIS10.0\lib\site-packages\PIL\Image.py", line 1996, in merge 
    if im.mode != getmodetype(mode): 
AttributeError: 'str' object has no attribute 'mode' 

任何想法将不胜感激

请您参考如下方法:

m, c, y and k 需要是PIL Image 对象，例如

m = Image.open("C:\Documents and Settings\dbigwood\Desktop\TEST\magnew.tif")
