How to run gif one time in tkinter?
问题
以下是代码的翻译部分：
from tkinter import *
import time
import os
root = Tk()
frameCnt = 12
frames = [PhotoImage(file='mygif.gif', format='gif -index %i' % (i)) for i in range(frameCnt)]
def update(ind):
frame = frames[ind]
ind += 1
if ind == frameCnt:
ind = 0
label.configure(image=frame)
root.after(100, update, ind)
label = Label(root)
label.pack()
root.after(0, update, 0)
root.mainloop()
请注意，代码部分未进行翻译。

frames = [PhotoImage(file='mygif.gif',format = 'gif -index %i' %(i)) for i in range(frameCnt)]
def update(ind):
frame = frames[ind]
ind += 1
if ind == frameCnt:
ind = 0
label.configure(image=frame)
root.after(100, update, ind)
label = Label(root)
label.pack()
root.after(0, update, 0)
root.mainloop()
I want to run file gif one time when i opened window .

如果您只想播放GIF一次，就像Bryan的评论所说，无需重置索引。
硬编码的frameCnt不够灵活，因为如果使用另一个GIF图像，它需要进行更改。
此外，与Pillow模块相比，使用tkinter.PhotoImage()从GIF图像加载帧速度较慢，所以我建议使用Pillow模块。
import tkinter as tk
from PIL import Image, ImageTk, ImageSequence
root = tk.Tk()
label = tk.Label(root)
label.pack()
im = Image.open('mygif.gif')
frames = [ImageTk.PhotoImage(frame) for frame in ImageSequence.Iterator(im)]
def update(idx=0):
if idx < len(frames):
label.configure(image=frames[idx])
root.after(100, update, idx+1)
update() # 开始动画
root.mainloop()
英文:
If you want to animate the GIF only once, you don't need to reset the index as said by Bryan's comment.
Hard-coded frameCnt is not flexible because it need to be changed if another GIF image is used.
Also using tkinter.PhotoImage() to load frames from a GIF image is a bit slow when comparing with Pillow module, so I would suggest to use Pillow module.
import tkinter as tk
from PIL import Image, ImageTk, ImageSequence
root = tk.Tk()
label = tk.Label(root)
label.pack()
im = Image.open('mygif.gif')
frames = [ImageTk.PhotoImage(frame) for frame in ImageSequence.Iterator(im)]
def update(idx=0):
if idx < len(frames):
label.configure(image=frames[idx])
root.after(100, update, idx+1)
update() # start the animation
root.mainloop()

如Bryan Oakley评论所述，我们已经在检查计数，所以我们只是退出函数。
from tkinter import *
import time
import os
root = Tk()
frameCnt = 12
frames = [PhotoImage(file='mygif.gif', format='gif -index %i' % (i)) for i in range(frameCnt)]
def update(ind):
frame = frames[ind]
ind += 1
label.configure(image=frame)
if ind == frameCnt:
return
root.after(500, update, ind)
label = Label(root)
label.pack()
root.after(0, update, 0)
root.mainloop()
英文:
As Bryan Oakley commented, we're already checking the count, so we just exit the function.
from tkinter import *
import time
import os
root = Tk()
frameCnt = 12
frames = [PhotoImage(file='mygif.gif',format = 'gif -index %i' %(i)) for i in range(frameCnt)]
def update(ind):
frame = frames[ind]
ind += 1
label.configure(image=frame)
if ind == frameCnt:
return
root.after(500, update, ind)
label = Label(root)
label.pack()
root.after(0, update, 0)
root.mainloop()
