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 matches highlighted images on a pixel-by-pixel basis, so on systems with different resolutions will fail to find images.
Therefore is there a way that I can change the resolution settings in windows through java code?
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)
Therefore is there a way that I can change the resolution settings in windows through java code?
1.yes is possible, why not

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
(layed with proper LayoutManager
into container), or put Icons
to the JList
or JTable
, then you never / don't care about something
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
