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)

安装

pip install imageio-ffmpeg
pip install imageio

Code

import imageio
images = []
for filename in filenames:
    images.append(imageio.imread(filename))
imageio.mimsave('movie.mp4', images)

当保存为mp4而不是gif时，质量提高，大小从8Mb减少到80Kb

我使用images2gif.py，这很容易使用。它似乎是文件大小的两倍。

26个110kb的PNG文件，我期望26*110kb = 2860kb，但my_gif.GIF是5.7mb

另外，因为GIF是8位的，好看的png在GIF中变得有点模糊

下面是我使用的代码:

__author__ = 'Robert'
from images2gif import writeGif
from PIL import Image
import os

file_names = sorted((fn for fn in os.listdir('.') if fn.endswith('.png')))
#['animationframa.png', 'animationframb.png', 'animationframc.png', ...] "

images = [Image.open(fn) for fn in file_names]

print writeGif.__doc__
# writeGif(filename, images, duration=0.1, loops=0, dither=1)
#    Write an animated gif from the specified images.
#    images should be a list of numpy arrays of PIL images.
#    Numpy images of type float should have pixels between 0 and 1.
#    Numpy images of other types are expected to have values between 0 and 255.


#images.extend(reversed(images)) #infinit loop will go backwards and forwards.

filename = "my_gif.GIF"
writeGif(filename, images, duration=0.2)
#54 frames written
#
#Process finished with exit code 0

以下是26帧中的3帧:

缩小图像会减小尺寸:

size = (150,150)
for im in images:
    im.thumbnail(size, Image.ANTIALIAS)

Smart Manoj回答:从文件夹中的所有图像制作一个.mp4电影

安装:

pip install imageio-ffmpeg
pip install imageio

代码:

import os
import imageio

root = r'path_to_folder_with_images'

images = []    
for subdir, dirs, files in os.walk(root):
    for file in files:
        images.append(imageio.imread(os.path.join(root,file)))

savepath = r'path_to_save_folder'
imageio.mimsave(os.path.join(savepath,'movie.mp4'), images)

PS:确保你的“文件”列表按照你想要的方式排序，如果你已经相应地保存了你的图像，你会节省一些时间

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')

就像沃伦去年说的，这是一个老问题。由于人们似乎仍然在浏览页面，我想将他们重定向到一个更现代的解决方案。就像blakev说的，github上有一个枕头的例子。

 import ImageSequence
 import Image
 import gifmaker
 sequence = []

 im = Image.open(....)

 # im is your original image
 frames = [frame.copy() for frame in ImageSequence.Iterator(im)]

 # write GIF animation
 fp = open("out.gif", "wb")
 gifmaker.makedelta(fp, frames)
 fp.close()

注意:这个例子已经过时了(gifmaker不是一个可导入的模块，只是一个脚本)。Pillow有一个GifImagePlugin(其源代码在GitHub上)，但ImageSequence上的文档似乎表明有限的支持(只读)
