如何定期更改图像和标签值

Question

我有两个问题是关于你定期更改图像的代码。我已经运行了你的代码和图像的变化非常好，但当我试图把你的补丁与我的图像是不按顺序和随机图像生成。我的代码是关于websocket程序的，其中rpi是客户机，esp32是服务器，数据是以sprintf格式来的

问题是，我必须采取的数据和粘贴的图像，我在我的目录。 共有4幅图像，每幅图像有4个不同的参数

我的第二个问题是，当图像改变时，数据也应该周期性地改变。我还可以设置图像的计时，比如哪个图像应该首先显示，以及它的数据

如果你能在这件事上启发我，那将是一个很大的帮助。 我把我的代码放在下面供你参考

代码：

import tkinter as Tk
import tkinter as tk
from tkinter import *
import websocket
from PIL import Image, ImageTk
from parse import *
import image
import itertools
import os
import sys
import shutil

def update_image(dst):
    test_image = '/home/pi/Desktop/kvar pix exb/KVAR PIX P1.jpg', '/home/pi/Desktop/kvar pix exb/KVAR PIX P2.jpg', '/home/pi/Desktop/kvar pix exb/KVAR PIX P3.jpg','/home/pi/Desktop/kvar pix exb/KVAR PIX P4.jpg'

    for src in itertools.cycle(test_image):
        shutil.copy(src, dst)
        time.sleep(1)  # pause between updates

def refresh_image(canvas,img,image_path,image_id):
    try:
        pil_img = Image.open(image_path).resize((width_value,height_value), Image.ANTIALIAS)
        img = ImageTk.PhotoImage(pil_img)
        canvas.itemconfigure(image_id,image=img)
    except IOError:
        img = None
    #repeat every half sec
    canvas.after(500,refresh_image,canvas,img,image_path,image_id)

image_path = 'test.png'

    while 1:
        result = ws.recv()
        incoming_data = result.split(',')
        while 1:
            if (incoming_data[1] != comparing_data[1]):
                print("unauthorised server")
            else:
                break
        print(incoming_data)
        labeltxt_1.set(' '+incoming_data[2])
        labeltxt_2.set(' '+incoming_data[3])
        labeltxt_3.set(' '+incoming_data[4])
        labeltxt_4.set(' '+incoming_data[5])
        labeltxt_5.set(' '+incoming_data[6])
        labeltxt_6.set(' '+incoming_data[7])
        labeltxt_7.set(' '+incoming_data[8])
    ws.close()
