如何从 PowerPoint 导出高分辨率（高 dpi）幻灯片 - Office | Microsoft Learn
总结为：改注册表。
顺手写个脚本：
代码语言：javascript复制import tkinter as tk
from tkinter import ttk
import winreg
from tkinter import messagebox
class App(tk.Frame):

super().__init__(master)
self.master = master

"PowerPoint 2010": "14.0",
"PowerPoint 2007": "12.0",
"PowerPoint 2003": "11.0",
