[源码]Python Tkiner 写的截图小工具 实现了大部分基础功能

本文主要是介绍[源码]Python Tkiner 写的截图小工具 实现了大部分基础功能,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!
最近在写一些小工具,因为是给别人用的需要界面,刚开始使用pyQT5 功能强大,但是打包后一个小工具 就有几十兆 有点蛋疼而且还很消耗资源;后面改用TK,TK明显简洁很多,功能同样也若很多!
因为有截图需求,就抽空写了这个工具,全当练习。过程当中遇到过好多蛋疼的事情,功能基本实现后发出来给大家分享一下,我个人还是比较喜欢python这门语言的!
实现思路:
3.1.新建一个最小化窗口,利用线程启动监听"ctrl+a"启动截图窗口
3.2.截图窗口初始化时利用 pyautogui.screenshot 截取全屏(类似PRTSC)作为子窗口的背景(在这搞了好久,后面没办法只有利用canvas设置背景),子窗口最大化取消菜单栏
3.3.在主窗口上的canvas上用绑定鼠标事件,根据鼠标选取截图范围,和鼠标操作相关功能
3.4.保存功能是根据截图范围重新截图生成文件保存
