一、安装库
需要安装pywin32库
pip install pywin32
二、代码原理
WPS高清图片导出需要会员，就为了一个这个小需求开一个会员太亏了，因此就使用python对ppt进行高清图片导出。
设置format=19即可：
ppt.SaveAs(imgs_path, 19)
三、使用效果
输入一个文件路径
path = 'D:\\自动化\\课件.pptx'
最后的效果：
会在路径下创建一个‘’课件‘’文件夹
里面是所有转换后的图片
四、所有代码
完整代码如下
# -*- coding: UTF-8 -*-
import os
import sys
def get_all_ppts(path):
# 获取所有 ppt 文件
ppt_paths = []
for root, _, files in os.walk(path):
for f in files:
suffix = os.path.splitext(f)[-1].lower()
if 'ppt' in suffix:
ppt_paths.append(os.path.join(root,f))
return ppt_paths
