Python 视频（连续图片）转gif动图_pil gif 循环

之前写了一个转gif格式的代码= = 。

import os
import cv2
from PIL import Image
 
def to_gif(video_path,save_path,name,start,time,timeF=1,end=-9999,ratio = 1,loop=0):
    '''
    parameter:
        video_path:视频路径
        save_path:gif保存路径
        name:保存gif的名字
        start:希望开始的时间
        end:希望结束的时间
        time:图片切换的时间
        timeF:隔多久拆帧，默认为1
        ratio:缩放比率，默认为1，原图大小
        loop:播放模式，默认为0，循环播放，1为只播放一次
    return:
        None
    
    '''
    capture = cv2.VideoCapture(video_path)       #生成视频读取对象
    width = int(capture.get(3))                  #获取视频的长度

    times = 0
    img_list = []                                #构建用于存放帧数组的空列表

代码经过调试了滴，可以直接用~
