Python3 Tkinter and Pillow:如何在画布上旋转图像

from tkinter import *
from PIL import Image, ImageTk

root = Tk()
canvas = Canvas(root, width=500, height=500)
canvas.pack()

image = Image.open("image.jpg")

def rotate_image(angle):
    rotated_image = image.rotate(angle)
    tk_image = ImageTk.PhotoImage(rotated_image)
    canvas.create_image(250, 250, image=tk_image)
    canvas.image = tk_image

rotate_button = Button(root, text="旋转", command=lambda: rotate_image(45))
rotate_button.pack()

angle_slider = Scale(root, from_=0, to=360, orient=HORIZONTAL)
angle_slider.pack()

root.mainloop()
