Jam*_*ers 2 java swing screen-resolution sikuli
我有一个程序,它使用可视化脚本(sikuli-script)来允许用户创建自己的可视化脚本。该程序需要跨多个可能具有不同屏幕分辨率的系统运行。
Sikuli 逐像素匹配突出显示的图像,因此在不同分辨率的系统上将无法找到图像。
那么有没有一种方法可以通过java代码更改Windows中的分辨率设置?
不能选择全屏,因为需要捕获的图像来自不同的软件包,即我的软件包位于图像需要来自的上方(并且在捕获时最小化)
那么有没有一种方法可以通过java代码更改Windows中的分辨率设置?
1.是的,这是可能的,为什么不呢

2.不要这样做,可能会惹恼用户,并且在代码上缺乏可以更改分辨率的功能Native OS(我的同事在三个屏幕上有超过100个快捷方式,任何更改分辨率都可以更改截图size,location结果很简单)
3.使用JLabelfor Icons(与适当的LayoutManager放入容器中),或放入Icons或JList,JTable那么你永远/不关心某事
4.仅使用而不是定位或更改屏幕分辨率,您可以在屏幕上LayoutManager设置较小Size(为),让用户在她/他的屏幕上决定最终结果JFrameApps start_upDimmension
