我怎么能直接蟒蛇的Tkinter与他们的显示器之间的延迟,以显示顺序2个图像?

问题描述 投票:-1回答:1

我想说明使用Tkinter的一些延迟蟒蛇两个图像,但我不能。我用这个代码:

import sys
import time
if sys.version_info[0] == 2:  # the tkinter library changed it's name from Python 2 to 3.
    import Tkinter
    tkinter = Tkinter #I decided to use a library reference to avoid potential naming conflicts with people's programs.
else:
    import tkinter
from PIL import Image, ImageTk

def showPIL(pilImage):
    root = tkinter.Tk()
    w, h = root.winfo_screenwidth(), root.winfo_screenheight()
    root.overrideredirect(1)
    root.geometry("%dx%d+0+0" % (w, h))
    root.focus_set()    
    root.bind("<Escape>", lambda e: (e.widget.withdraw(), e.widget.quit()))
    canvas = tkinter.Canvas(root,width=w,height=h)
    canvas.pack()
    canvas.configure(background='black')
    imgWidth, imgHeight = pilImage.size
    if imgWidth > w or imgHeight > h:
        ratio = min(w/imgWidth, h/imgHeight)
        imgWidth = int(imgWidth*ratio)
        imgHeight = int(imgHeight*ratio)
        pilImage = pilImage.resize((imgWidth,imgHeight), Image.ANTIALIAS)
    image = ImageTk.PhotoImage(pilImage)
    imagesprite = canvas.create_image(w/2,h/2,image=image)
    root.mainloop()

和该功能后,用于显示图像:

pilImage = Image.open("colagem3.png")
showPIL(pilImage)
time.sleep(2)
pilImage = Image.open("colagem3.png")
showPIL(pilImage)
time.sleep(2)

为什么它不工作?

我不知道这是肯定你的问题在这里,但sleep()功能是不会,如果你还没有导入模块,它得到认可。您可以通过将from time import sleep导入。此外,如果你正在使用Python 3或没有运行您的Windows操作系统的程序则PIL库是不会得到支持。
