整体处理并不理想，原始图片80KB，大图gif 1.3M,小图gif 801KB。

回头试试另一种方案：frame保存为jpg,降低quality到60，再合并jpg文件生成gif，最后移除jpg文件

2022-08-10实验后记录：

保存jpg再合并的方案不合理，jpg单个文件10kb左右，85个文件合并后是2.7M。

庆幸有pygifsicle

第一种方案生成gif是1.3M,压缩后70kb

pip install pygifsicle

使用：

from pygifsicle import optimizeoptimize(destFile, colors=32)#新文件,color视情况而定optimize(destFile, "newFilePath", colors=32)
