如何使用PIL在Tkinter中显示在线.webp文件

Question

我有一个在线托管的动画。webp文件，我试图使用Tkinter显示它。这是我的代码。

import urllib.request
from PIL import Image, ImageTk
root=tkinter.Tk()
u = urllib.request.urlopen("https://..../.....webp")
raw_data = u.read()
u.close()
im = Image.open(BytesIO(raw_data))
image = ImageTk.PhotoImage(im.resize((470,210)))
Label(root,image=image).pack()
root.mainloop()

这不会引发任何错误，但只显示一帧。为什么会这样呢?有什么办法可以解决这个问题吗?

根据@Atlas435的评论，我编写了一个可以在tkinter中显示webp文件而无需下载的代码。这是代码:

from io import BytesIO
from tkinter import *
import tkinter
import urllib.request
from PIL import Image, ImageTk
root=tkinter.Tk()

ar=0
import tkinter as tk
from PIL import Image, ImageTk



u = urllib.request.urlopen(url)
raw_data = u.read()
u.close()

im = Image.open(BytesIO(raw_data))

from itertools import count

class ImageLabel(tk.Label):
"""a label that displays images, and plays them if they are gifs"""
def load(self, im):
if isinstance(im, str):
im = im
self.loc = 0
self.frames = []

try:
for i in count(1):
self.frames.append(ImageTk.PhotoImage(im.copy().resize((470,210))))
im.seek(i)
except EOFError:
pass

try:
self.delay = im.info['duration']
except:
self.delay = 100

if len(self.frames) == 1:
self.config(image=self.frames[0])
else:
self.next_frame()

def unload(self):
self.config(image="")
self.frames = None

def next_frame(self):
if self.frames:
self.loc += 1
self.loc %= len(self.frames)
self.config(image=self.frames[self.loc])
self.after(self.delay, self.next_frame)
lbl = ImageLabel(root)
lbl.pack()
lbl.load(im)
root.mainloop()
