如何使用tkinter添加背景图像

from tkinter import *
from PIL import ImageTk, Image

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

image = Image.open("background.jpg")  # 替换为你的背景图像文件路径
background_image = ImageTk.PhotoImage(image)
canvas.create_image(0, 0, anchor=NW, image=background_image)

button = Button(root, text="点击按钮")
canvas.create_window(250, 250, window=button)  # 将按钮添加到画布上

root.mainloop()
