how can I split a large image into small pieces in python

Question

I need to create 30 * 30 px small images from splitting a large image. I need these parts separately saved in separate files after being split up like so:

Answer 1

Here you go:

import cv2
img = cv2.imread('image.png')
for r in range(0,img.shape[0],30):
    for c in range(0,img.shape[1],30):
        cv2.imwrite(f"img{r}_{c}.png",img[r:r+30, c:c+30,:])

Answer 2

Try use image_slicer. (8 x 8 from your description)

import image_slicer

image_slicer.slice('C:\\files\\cars.png', 64)

This' how the outputs looked like.
