Starting with this image where the coloured part is 224x224 on a black background of 320x240.

enter image description here

I would just use numpy to crop like this:

#!/usr/local/bin/python3
from PIL import Image
import numpy as np

# Open the image and convert to numpy array
im=Image.open('start.png')
im=np.array(im)

# Work out where top left corner is
y=int((320-224)/2)
x=int((240-224)/2)

# Crop, convert back from numpy to PIL Image and and save
cropped=im[x:x+224,y:y+224]
Image.fromarray(cropped).save('result.png')

enter image description here
