批量修改图片大小好像用PS也可以,不过我不会,程序猿就用程序来解决。
这段时间学了下Python,很强大,之前一些不知道怎么处理的东西在Python里面都能找到解决方法。
工具界面如下图
这个工具需要用到第三方库 Pillow 和 Pyqt5,可通过命令行安装。
pip install pillow pip install pyqt5
代码:
#!-*-coding:utf-8-*- from PIL import Image import hashlib, os, sys from PyQt5.QtGui import QFont, QIcon from PyQt5.QtWidgets import (QFileDialog, QMessageBox, QGridLayout, QLineEdit, QTextEdit,

整个工具比较简陋,能用就好。有什么不正确的地方请指出。
以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持。

稳了!魔兽国服回归的3条重磅消息!官宣时间再确认!
昨天有一位朋友在大神群里分享,自己亚服账号被封号之后居然弹出了国服的封号信息对话框。
这里面让他访问的是一个国服的战网网址,com.cn和后面的zh都非常明白地表明这就是国服战网。
而他在复制这个网址并且进行登录之后,确实是网易的网址,也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情,因为以前都没有出现这样的情况,现在突然提示跳转到国服战网的网址,是不是说明了简体中文客户端已经开始进行更新了呢?
