FindDiff_Qt找不同项目

项目简介

• 开发平台

  • win10
  • Qt6.6
  • msvc2022

• 简介

  微信上有一些好玩的游戏, 找不同一种比较轻松有趣的游戏,也曾经在街机上被坑过N币, 玩了几次后,发现还是太难了,于是开始截屏放大,慢慢找,再然后就发展到截图发送到QQ的我的电脑里,用程序查找标记

  看效果:

  • 截屏的图

• FindDiff_Qt Qt 版本的找不同
  • 交互性强点
  • 用 ps 2019 切片比较方便
  • 默认 qq的 “我的电脑”的目录并自动监视该目录,当有新的文件出现时,会自动加载并查找不同处，而且每次对比前会自动删除该目录下的其他jpg图片，需要注意
