Python实现对PPT文件进行截图操作的方法

import osimport comtypes.clientdef 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()
