Python resizing animated gif with PIL

Question

I follow the step at Resize GIF animation, pil/imagemagick, python to resize image using PIL and image2gif. However, I got the resized gif washed out like below:

How do I solve this problem?

Answer 1

Here is my code

from PIL import Image, ImageSequence

filename = "demo.gif"
new_width = 100
new_height = 100

with Image.open(filename) as im:
    frames = []
    for frame in ImageSequence.Iterator(im):
        frame = frame.resize((new_width, new_height))
        frames.append(frame)
    print(f"length of freames {len(frames)}")
    frames[0].save('resized_image.gif', save_all=True, append_images=frames[1:])
