python+tkinter+pyautogui 自制截屏軟件

目標：雖然類似QQ等軟件帶有截屏功能，但還是感覺自造的好

使用說明：將以下代碼保存為如：截屏.pyw    並發送到 桌面快捷方式  然后修改快捷方式的屬性 增加快捷鍵。

現在可以用快捷鍵啟動腳本截屏了。

然而：win10自帶的  “Win+Shift+S”組合鍵便可進入截屏模式

代碼：

#! /usr/bin/env python

import tkinter as tk

# root.attributes("-alpha", 0.3)    # 窗口透明度70 %
root.attributes("-alpha", 0.4)      # 窗口透明度60 %
#root.geometry("300x200+10+10")      # 設置窗口大小與位置
root.geometry("{0}x{1}+0+0".format(root.winfo_screenwidth(), root.winfo_screenheight()))
