Cropping an image with Python Pillow

Question

I installed Python Pillow and am trying to crop an image.

Other effects work great (for example, thumbnail, blurring image, etc.)

Whenever I run the code below I get the error:

tile cannot extend outside image

test_image = test_media.file original = Image.open(test_image)  width, height = original.size   # Get dimensions left = width/2 top = height/2 right = width/2 bottom = height/2 cropped_example = original.crop((left, top, right, bottom))  cropped_example.show() 

I used a cropping example I found for PIL, because I couldn't find one for Pillow (which I assumed would be the same).

Answer 1

The problem is with logic, not Pillow. Pillow is nearly 100% PIL compatible. You created an image of 0 * 0 (left = right & top = bottom) size. No display can show that. My code is as follows

from PIL import Image  test_image = "Fedora_19_with_GNOME.jpg" original = Image.open(test_image) original.show()  width, height = original.size   # Get dimensions left = width/4 top = height/4 right = 3 * width/4 bottom = 3 * height/4 cropped_example = original.crop((left, top, right, bottom))  cropped_example.show() 

Most probably this is not what you want. But this should guide you towards a clear idea of what should be done.
