使用tkinter在python中播放动画GIF [英] Play an Animated GIF in python with tkinter

问题描述

我想使用python3和tkinter创建一个虚拟的宠物风格游戏.到目前为止，我已经有了主窗口并开始放入标签，但是我遇到的问题是播放动画gif.我在这里搜索并找到了一些答案，但是他们不断抛出错误.我发现使用PhotoImage的结果具有gif的索引位置，并在一定范围内继续.

I am wanting to create a virtual pet style game using python3 and tkinter. So far I have the main window and have started putting labels in, but the issue I am having is playing an animated gif. I have searched on here and have found some answers, but they keep throwing errors. The result I found has the index position of the gif using PhotoImage continue through a certain range.

    # Loop through the index of the animated gif
frame2 = [PhotoImage(file='images/ball-1.gif', format = 'gif -index %i' %i) for i in range(100)]

def update(ind):

    frame = frame2[ind]
    ind += 1
    img.configure(image=frame)
    ms.after(100, update, ind)

img = Label(ms)
img.place(x=250, y=250, anchor="center")

ms.after(0, update, 0)
ms.mainloop()

当我在终端中使用"pyhton3 main.py"运行此命令时，出现以下错误:

When I run this in terminal with "pyhton3 main.py" I get the following error:

_tkinter.TclError:该索引没有图像数据

_tkinter.TclError: no image data for this index

我俯视什么或完全忽略了什么?

What am I overlooking or completely leaving out?

推荐答案

该错误表示您尝试加载100帧，但是gif小于该帧.

The error means that you tried to load 100 frames, but the gif has less than that.

众所周知，tkinter中的gif动画效果很差.我很早以前就编写了这段代码，您可以从中窃取代码，但是除了小gif以外，其他任何东西都不会让您满意:

Animated gifs in tkinter are notoriously bad. I wrote this code an age ago that you can steal from, but will get laggy with anything but small gifs:

import tkinter as tk
from PIL import Image, ImageTk
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 = Image.open(im)
        self.loc = 0
        self.frames = []

        try:
            for i in count(1):
                self.frames.append(ImageTk.PhotoImage(im.copy()))
                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)

root = tk.Tk()
lbl = ImageLabel(root)
lbl.pack()
lbl.load('ball-1.gif')
root.mainloop()
