Python实现批量将PPT转换成长图

作者:谷雨之际

这篇文章主要为大家详细介绍了如何利用Python实现批量将PPT转换成长图,并且图片名称与PPT文件名称相同,保存位置相同,感兴趣的小伙伴可以了解下

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 Image

 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 = None
