在tkinter中拍摄应用程序窗口/标签的“屏幕截图”

from PIL import ImageGrab
import tkinter as tk

root = tk.Tk()

def take_screenshot():
    # 获取屏幕尺寸
    screen_width = root.winfo_screenwidth()
    screen_height = root.winfo_screenheight()
    
    # 获取窗口位置
    window_x = root.winfo_rootx()
    window_y = root.winfo_rooty()
    
    # 计算窗口在屏幕上的位置
    x = window_x
    y = window_y
    width = window_x + root.winfo_width()
    height = window_y + root.winfo_height()
    
    # 截取屏幕图像
    image = ImageGrab.grab(bbox=(x, y, width, height))
    
    # 保存图像
    image.save("screenshot.png")

button = tk.Button(root, text="Take Screenshot", command=take_screenshot)
button.pack()

root.mainloop()
