This article explains how to crop and display an image using tkinter. The function used is crop. Note that a method for simply displaying an image is explained here.

■An example of the crop function
The "crop" part below corresponds to the process of cutting out an image.

import tkinter as tk
from PIL import Image, ImageTk

app = tk.Tk()
img = Image.open('test.jpg')

crop_img = img.crop((100, 100, 300, 300)) # Crop the image to the range 100,100~300,300

tk_img = ImageTk.PhotoImage(crop_img)
img_width, img_height = img.size

canvas = tk.Canvas(app, width=img_width, height=img_height) # Creating an image display area
canvas.pack()
canvas.create_image(0, 0 , anchor = tk.NW, image=tk_img) # Image display

app.mainloop()

The results are below, with the original image on the left.
