Error saving an image using PIL

Question

I am trying to use the getbbox to crop a picture and then save it. However I keep on getting a certain error that I don't know how to fix.

The code:

 import ImageOps
 import Image

 im=Image.open("b1.jpg")
 invert_im = ImageOps.invert(im) # because the boundary is white so I convert it to black so I can crop the photo
 im2 =invert_im.getbbox() 
 invert_im = ImageOps.invert(im2) # invert back
 invert_im.save("b1_cropped.jpg") 

The error I am receiving:

AttributeError: 'tuple' object has no attribute 'save'

Any ideas?

Answer 1

import ImageOps
import Image
im=Image.open("b1.jpg")
inverted = ImageOps.invert(im)
box = inverted.getbbox()
cropped_im = im.crop(box)
cropped_im.save("b1_cropped.jpg")

This should be the answer.
