使用Python 3.4和Pillow以及方法转换：AttributeError：图像

Question

I have tried to make the following script running correctly:

def tftest():
    from PIL import Image
    picture = "ttamet3dim.png"
    impict = Image.open(picture)
    transf = impict.Image.transform((78,78), Image.QUAD, (78,41,178,27,183,91,81,91), Image.BICUBIC)
    imt = Image.open(transf)
    imt.show()

But I get the following error:

File "C:\Python34\tftest.py", line 5, in tftest
    transf = impict.Image.transform(...)
File "C:\Python34\lib\site-packages\pillow-3.0.0-py3.4-win32.egg\PIL\Image.py", line 626, in __getattr__
AttributeError: Image

It's the first time that I use "transform" . I wanted to have a look to the "transform" script to see if I could find out what's wrong but my Pillow is a .egg so I didn't find how to access to the code. Do you know why I get this error and how to fix it? Thank you, best regards

Answer 1

transform is a method for Image objects, and returns a new image:

from PIL import Image

def tftest():
    picture = "ttamet3dim.png"
    impict = Image.open(picture)
    imt = impict.transform((78,78), Image.QUAD, (78,41,178,27,183,91,81,91), Image.BICUBIC)
    imt.show()

Answer 2

尝试将transf = impict.Image.transform transf = impict.transform更改transf = impict.Image.transform transf = impict.transform

Answer 3

You've assigned the Image to the impict variable here:

impict = Image.open(picture)

you should reference this variable, that's the opened image, with the transform:

impict.transform

instead of what you're currently doing (basically Image.open(picture).Image.transform ).
