问题描述
我有一个使用可视化脚本()的程序,允许用户创建自己的可视脚本。该程序需要跨多个可能具有不同屏幕分辨率的系统工作。
I have a program that uses visual scripting (sikuli-script) to allow the users to create their own visual scripts. The program needs to work across multiple systems that could have different screen resolutions.
Sikuli在逐个像素的基础上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。
Sikuli matches highlighted images on a pixel-by-pixel basis, so on systems with different resolutions will fail to find images.
因此有没有办法可以通过java代码在Windows中更改分辨率设置?
Therefore is there a way that I can change the resolution settings in windows through java code?
全屏显示不是一个选项,因为需要的图像被捕获来自不同的软件包,即我的软件包位于图像需要来自的位置(并且在捕获时最小化)
Going full-screen is not an option as images that need to be captured come from different software packages, i.e. my software package sits above where the images need to come from (and is minimized when a capture is taking place)

1.是可能的,为什么不呢

2.不要这样做,可能会让用户烦恼,代码缺乏可以改变 Native OS
的分辨率(我的同事在三个屏幕上有超过100个切换,任何更改分辨率以更改切割大小
和 location
,结果很简单)
2.don't do that, could annoying users, and on code lack can to change resolution in Native OS
(my coworker has more than 100shortcuts on three screen, any change for resolution to change shotcuts size
and location
, result is simple mess)
3.use JLabel
for Icons
(使用适当的 LayoutManager
放入容器中),或者放图标
到 JList
或 JTable
,然后你永远/不要关心某事
3.use JLabel
for Icons
(layed with proper LayoutManager
into container), or put Icons
to the JList
or JTable
, then you never / don't care about something
4.只使用 LayoutManager
而不是为屏幕分辨率进行排序或改变,你可以设置 Apps start_up 大小
(对于 JFrame
) c>,让我们的用户在她/他的屏幕上决定最终的 Dimmension
4.use only LayoutManager
rather than possitioning or change for screen resolution, you can set for smaller Size
(for JFrame
) on the screen for Apps start_up
, let's user decide about final Dimmension
on her/his screen
