利用Python实现无损GIF动图的制作

import imageio

def create_gif(image_list, gif_name, duration=0.35):
    frames = []
    for image_name in image_list:
        frames.append(imageio.imread(image_name))
    imageio.mimsave(gif_name, frames, 'GIF', duration=duration)
    return

def main():
    image_list = ['car/10.jpg','car/15.jpg','car/8.jpg',]
    gif_name = 'car/car.gif'
    duration = 1.15
    create_gif(image_list, gif_name, duration)

if __name__ == '__main__':
    main()

import imageio
from PIL import Image, ImageSequence

rp = 1000   

img_list = []

# 读取原gif动图
img = Image.open("car/car.gif")

# 对原动图进行压缩，并存入img_list 
for i in ImageSequence.Iterator(img):
    i = i.convert('RGB')
    if max(i.size[0], i.size[1]) > rp:
        i.thumbnail((rp, rp))
    img_list.append(i)

# 计算帧的频率
durt = (img.info)['duration'] / 1000

# 读取img_list合成新的gif
imageio.mimsave('car/car1.gif', img_list, duration=durt )
