我有一个程序使用可视化脚本 ( sikuli-script ) 来允许用户创建他们自己的可视化脚本。该程序需要跨多个可能具有不同屏幕分辨率的系统工作。
Sikuli 逐个像素地匹配突出显示的图像,因此在具有不同分辨率的系统上将无法找到图像。
有没有办法通过java代码改变windows的分辨率设置?
全屏不是一个选项,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位置上方(并且在捕获时最小化)
最佳答案
Therefore is there a way that I can change the resolution settings in windows through java code?
1.yes是可能的,为什么不

2.不要那样做,可能会惹恼用户,并且缺少代码可以在 Native OS
中更改分辨率(我的同事在三个屏幕上有超过 100 个快捷方式,任何更改分辨率都会更改shotcuts size
和 location
,结果很简单)
3.使用JLabel
作为Icons
(使用合适的LayoutManager
放置到容器中),或者把Icons
放到JList
或 JTable
,那么您永远/不关心某些事情
4.只使用 LayoutManager
而不是定位或更改屏幕分辨率,您可以在Apps start_up
的屏幕,让用户决定她/他的屏幕上的最终 Dimension
关于java - 在 Java 中更改屏幕分辨率,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/11225113/
