这是一个关于把多图片合成GIF动图的python实现方法一文，完成这项操作的大体思路如下，源码供参考，如有不足能自行修改后再使用。

#type 合成GIF分类

#0：图片缩放到最大宽度*最大高度(长方形)、并粘贴到最大宽度*最大高度(长方形)的白色背景图片中、居中后合成

#1：图片缩放到最大长度(正方形)、并粘贴到最大长度(正方形)的白色背景图片中、居中后合成

#2：图片不缩放、并粘贴到最大宽度*最大高度(长方形)的白色背景图片中、居中后合成

#3：图片不缩放、并粘贴到最大长度(正方形)的白色背景图片中、居中后合成

#4：原图直接合成(按宽度排序、不缩放也不粘贴到新的白色背景图片中)

#5：原图直接合成(按高度排序、不缩放也不粘贴到新的白色背景图片中)
