如何在tkinter窗口中查找特定像素

import tkinter as tk
from PIL import Image

def find_pixel(image_path, target_pixel):
    # 创建tkinter窗口
    window = tk.Tk()
    window.title("Pixel Finder")
    
    # 加载图像
    img = Image.open(image_path)
    pixels = img.load()
    
    # 遍历图像的每个像素
    for y in range(img.height):
        for x in range(img.width):
            # 获取当前像素的RGB值
            r, g, b = pixels[x, y]
            
            # 判断当前像素是否为目标像素
            if (r, g, b) == target_pixel:
                # 找到目标像素，执行相应操作（这里仅打印坐标）
                print("Found target pixel at ({}, {})".format(x, y))
    
    # 更新tkinter窗口显示的图像
    img_tk = ImageTk.PhotoImage(img)
    label = tk.Label(window, image=img_tk)
    label.pack()
    
    # 运行tkinter窗口的主循环
    window.mainloop()

# 示例调用
image_path = "path/to/your/image.jpg"
target_pixel = (255, 0, 0)  # 目标像素为红色
find_pixel(image_path, target_pixel)
