下面是如何使用PIL (install with: pip install Pillow):

import glob
import contextlib
from PIL import Image

# filepaths
fp_in = "/path/to/image_*.png"
fp_out = "/path/to/image.gif"

# use exit stack to automatically close opened images
with contextlib.ExitStack() as stack:

    # lazily load images
    imgs = (stack.enter_context(Image.open(f))
            for f in sorted(glob.glob(fp_in)))

    # extract  first image from iterator
    img = next(imgs)

    # https://pillow.readthedocs.io/en/stable/handbook/image-file-formats.html#gif
    img.save(fp=fp_out, format='GIF', append_images=imgs,
             save_all=True, duration=200, loop=0)

我看到这篇文章，没有一个解决方案是有效的，所以这里是我的解决方案是有效的

到目前为止，其他解决方案存在的问题: 1)对于如何修改持续时间没有明确的解决方案 2)对于乱序目录迭代没有解决方案，而乱序目录迭代对于动图是必不可少的 3)没有说明如何为python3安装imageio

像这样安装imageio: python3 -m PIP Install imageio

注意:你要确保你的帧在文件名中有某种索引，这样它们就可以排序，否则你就无法知道GIF从哪里开始或结束

import imageio
import os

path = '/Users/myusername/Desktop/Pics/' # on Mac: right click on a folder, hold down option, and click "copy as pathname"

image_folder = os.fsencode(path)

filenames = []

for file in os.listdir(image_folder):
    filename = os.fsdecode(file)
    if filename.endswith( ('.jpeg', '.png', '.gif') ):
        filenames.append(filename)

filenames.sort() # this iteration technique has no built in order, so sort the frames

images = list(map(lambda filename: imageio.imread(filename), filenames))

imageio.mimsave(os.path.join('movie.gif'), images, duration = 0.04) # modify duration as needed

该任务可以通过在与图片文件序列相同的文件夹中运行两行python脚本来完成。对于png格式的文件，脚本是-

from scitools.std import movie
movie('*.png',fps=1,output_file='thisismygif.gif')

老问题，有很多很好的答案，但可能仍然对另一种选择感兴趣……

我最近在github (https://github.com/WarrenWeckesser/numpngw)上发布的numpngw模块可以从numpy数组写入动画PNG文件。(更新:numpngw现在在pypi: https://pypi.python.org/pypi/numpngw。)

例如，这个脚本:

import numpy as np
import numpngw


img0 = np.zeros((64, 64, 3), dtype=np.uint8)
img0[:32, :32, :] = 255
img1 = np.zeros((64, 64, 3), dtype=np.uint8)
img1[32:, :32, 0] = 255
img2 = np.zeros((64, 64, 3), dtype=np.uint8)
img2[32:, 32:, 1] = 255
img3 = np.zeros((64, 64, 3), dtype=np.uint8)
img3[:32, 32:, 2] = 255
seq = [img0, img1, img2, img3]
for img in seq:
    img[16:-16, 16:-16] = 127
    img[0, :] = 127
    img[-1, :] = 127
    img[:, 0] = 127
    img[:, -1] = 127

numpngw.write_apng('foo.png', seq, delay=250, use_palette=True)

创建:

你需要一个支持动画PNG的浏览器(直接或带有插件)才能看到动画。

我建议不要使用visvis的images2gif，因为它有PIL/Pillow的问题，并且没有积极维护(我应该知道，因为我是作者)。

相反，请使用imageio，它是为解决这个问题而开发的，并打算保留。

快速而肮脏的解决方案:

import imageio
images = []
for filename in filenames:
    images.append(imageio.imread(filename))
imageio.mimsave('/path/to/movie.gif', images)

对于较长的电影，使用流媒体方法:

import imageio
with imageio.get_writer('/path/to/movie.gif', mode='I') as writer:
    for filename in filenames:
        image = imageio.imread(filename)
        writer.append_data(image)

我偶然发现了PIL的ImageSequence模块，它提供了更好(更标准)的GIF动画。这次我也使用了Tk的after()方法，这比time.sleep()更好。

from Tkinter import * 
from PIL import Image, ImageTk, ImageSequence

def stop(event):
  global play
  play = False
  exit() 

root = Tk()
root.bind("<Key>", stop) # Press any key to stop
GIFfile = {path_to_your_GIF_file}
im = Image.open(GIFfile); img = ImageTk.PhotoImage(im)
delay = im.info['duration'] # Delay used in the GIF file 
lbl = Label(image=img); lbl.pack() # Create a label where to display images
play = True;
while play:
  for frame in ImageSequence.Iterator(im):
    if not play: break 
    root.after(delay);
    img = ImageTk.PhotoImage(frame)
    lbl.config(image=img); root.update() # Show the new frame/image

root.mainloop()
