making gif from images using imageio in python

Question

I have tried reading a lot of examples online and found imageio is the perfect package for it. Also found examples written in here.

I have just followed the example as shown and tried the following

import imageio as io
import os
file_names = sorted((fn for fn in os.listdir('.') if fn.startswith('surface')))
#making animation
with io.get_writer('surface.gif', mode='I', duration=0.5) as writer:
    for filename in file_names:
        image = io.imread(filename)
        writer.append_data(image)
writer.close()

and another example.

images = []
for filename in file_names:
    images.append(io.imread(filename))
io.mimsave('surface1.gif', images, duration = 0.5)

both of these do not work. And basically i only see the first frame from the gif and a blink and finish. The duration is set 0.5secs, so it should work fine. I might have been missing out something here.

Both approaches work on Python 2.7.1 and [´imageio´ 2.1.2](https://anaconda.org/conda-forge/imageio) ([1](https://drive.google.com/open?id=0By7vRQt-oAVdZXhtbU1yNUlQN0E) [2](https://drive.google.com/open?id=0By7vRQt-oAVdaUhhbmxVRnotT1U)), using several .png images. Are you sure all the images you want to use are being selected? Check the `file_names` list to see if they are all there. — berna1111, Mar 28 '17 at 10:18
I have tried the first approach. it works for about 758 .png files. But I have around 3000 .png files and the files after 758 are not appended in the .gif file. Is there any reason for that? I know the file_names array has those files. Refer https://stackoverflow.com/questions/44650649/why-is-my-gif-missing-png-files-after-250-iterations for more on my question. Thanks!! — user77005, Jun 21 '17 at 02:17

This works for me:

import os
import imageio

png_dir = '../animation/png'
images = []
for file_name in sorted(os.listdir(png_dir)):
    if file_name.endswith('.png'):
        file_path = os.path.join(png_dir, file_name)
        images.append(imageio.imread(file_path))

# Make it pause at the end so that the viewers can ponder
for _ in range(10):
    images.append(imageio.imread(file_path))

imageio.mimsave('../animation/gif/movie.gif', images)

This is the most easy and elegant solution I've found so far. One suggestion, add the sorted function before the list_dir function: `sorted(os.listdir(png_dir))` – Comos Feb 12 '21 at 14:38
I'm trying this solution, but the issue here is image transparency, while creating GIF some image color changed – Dhyn amicable Jul 23 '21 at 11:21
@Kunal you need to school yourself on getting a consistent color pallet across each gif before you combine them. – Dave Babbitt Jul 28 '21 at 08:30

@DaveBabbitt I am using this solution but facing color change issue in the image. Please use PIL but only one thing remember 1 second==100 mili second. – Dhyn amicable Jul 30 '21 at 10:47

How can we slow down the gif? – Mohamed Hachaichi Mar 31 '22 at 09:22

`imageio.mimsave` has a `duration=` parameter in seconds – Dave Babbitt Apr 01 '22 at 11:22

in case anyone needs it, for python 3.6.8, it needed fps

imageio.mimsave('/path/file.gif',images,fps=55)
