python代码——批量将PPT转换成长图

语言：python 3

用法：点击运行后，弹出窗口，选择文件夹，程序运行会将文件夹内的所有PPT文件全部转换成PPT长图，图片名称与PPT文件名称相同，保存位置相同。

如运行中报错，需要自行根据报错内容按照缺失的库

共分享两种代码，可以尝试运行。

代码1，需安装库

#安装库
pip install pyautogui
#安装库
pip install  pillow

import os
import comtypes.client
from tkinter import Tk, filedialog
from PIL import Imagedef ppt_to_images(ppt_file):try:# 导入comtypes.client模块并创建PowerPoint应用程序对象powerpoint = comtypes.client.CreateObject("Powerpoint.Application")# 设置PowerPoint应用程序为可见状态，便于观察操作过程（可选）,修改为0后报错#powerpoint.Visible = 1# 打开PPT文件，并返回Presentation对象presentation = powerpoint.Presentations.Open(ppt_file)for i, slide in enumerate(presentation.slides):      #slide是幻灯片序列slide.Export(f"slide_{i}.png", "PNG")# 关闭PPT文件presentation.Close()# 退出PowerPoint应用程序powerpoint.Quit()presentation = Noneprint(ppt_file+"分图完成！")except Exception as e:print("分图时发生错误：", str(e))

select_directory()
