如何在python opencv GUI中打印某些功能？

import cv2
from tkinter import *

window = Tk()
window.title("OpenCV GUI")

canvas = Canvas(window, width=800, height=600)
canvas.pack()

image = cv2.imread("image.jpg")
image = cv2.cvtColor(image, cv2.COLOR_BGR2RGB)  # 转换颜色空间
image = cv2.resize(image, (800, 600))  # 调整图像大小
image = Image.fromarray(image)  # 转换为PIL图像对象
image = ImageTk.PhotoImage(image)  # 转换为Tkinter图像对象
canvas.create_image(0, 0, anchor=NW, image=image)

def print_function():
    print("这是一个打印功能！")

button = Button(window, text="打印", command=print_function)
button.pack()

window.mainloop()
