python to batch split each image in a folder into multiple images

I. Up front

Requirements: there is a length of 960, width of 96 pictures, the need to split it into 10 96 * 96 pictures and stored in another folder, by hand split time-consuming and not standardized, choose python to write a simple program to complete.

III. Writing on the back

The number of cut rows and columns is defined here:

If you need to change the size of the image, you can simply use the resize() function in the PIL library with the following code:

from PIL import Image
 
for i in range(1,100):
 img = ("C:/Users/Administrator/Desktop/test_results/"+str(i)+".png")
 img = ("L")
 img = ((960,96))
 
 ("C:/Users/Administrator/Desktop/test_results/"+str(i)+".png", "PNG")
