ImageTK.PhotoImage 仅显示浅灰色屏幕

如何解决ImageTK.PhotoImage 仅显示浅灰色屏幕

我正在努力让 ImageTK.PhotoImage 正确显示。我总是得到一个全屏浅灰色屏幕而不是图像。

我已经尝试了大约 20 次不同的迭代与类中的函数等，但这里是当前的 -- 现在已经被充分破坏 -- 代码：

baseball.py

#!/usr/bin/python3
from game import Game
from menu import Menu
from display import ShowSplash
import tkinter as tk
from tkinter import ttk,Canvas
from PIL import Image,ImageTk



root = tk.Tk()
root.title('Baseball')
root.wm_attributes('-type','splash')
root.geometry(str(root.winfo_screenwidth()) + 'x' + str(root.winfo_screenheight()) + '+0+0')    
root['background'] = '#000000'
canvas = Canvas(root,width = root.winfo_screenwidth(),height = root.winfo_screenheight())
canvas.pack()

ShowSplash(canvas)

root.mainloop()

和display.py

import os
import time
import tkinter as tk
from tkinter import ttk
from PIL import Image,ImageTk

class ShowSplash:
    def __init__(self,canvas):
        self.canvas = canvas
        self.image = Image.open(os.path.join(os.getcwd(),'images/splash-screen.jpg'))
        self.splashScreenImage = ImageTk.PhotoImage(self.image)
        self.canvas.create_image(0,anchor='center',image=self.splashScreenImage)
        time.sleep(5)

有关如何使其正常工作的任何想法？
