Python为PPT文件进行截图操作的代码

下面的代码可以为powerpoint文件ppt进行截图，可以指定要截取的幻灯片页面，需要本机安装了powerpoint，可以指定截图的大小分辨率

import os
import comtypes.client

def export_presentation(path_to_ppt, path_to_folder):
    if not (os.path.isfile(path_to_ppt) and os.path.isdir(path_to_folder)):
        raise "Please give valid paths!"

    powerpoint = comtypes.client.CreateObject("Powerpoint.Application")

    # Needed for script to work, though I don't see any reason why...
    powerpoint.Visible = True

    powerpoint.Open(path_to_ppt)

    # Or some other image types
    powerpoint.ActivePresentation.Export(path_to_folder, "JPG")
    #这里可以写成：Presentation.Slides[1].Export("C:/path/to/jpg.jpg", "JPG", 800, 600);

    powerpoint.Presentations[1].Close()
    powerpoint.Quit()
