用Java更改屏幕分辨率

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。

因此有没有办法可以通过java代码更改Windows中的分辨率设置?

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上方(并且在捕获发生时最小化)

因此有没有办法可以通过java代码更改Windows中的分辨率设置?

1.是可能的,为什么不呢

import java.awt.Color; import java.awt.DisplayMode; import java.awt.Frame; import java.awt.Graphics; import java.awt.GraphicsConfiguration; import java.awt.GraphicsDevice; import java.awt.GraphicsEnvironment; import java.awt.Rectangle; import java.awt.image.BufferStrategy; public class MultiBufferTest { private Frame mainFrame; private static Color[] COLORS = new Color[]{ Color.red, Color.blue, Color.green, Color.white, Color.black, Color.yellow, Color.gray, Color.cyan, Color.pink, Color.lightGray, Color.magenta, Color.orange, Color.darkGray}; private static DisplayMode[] BEST_DISPLAY_MODES = new DisplayMode[]{ new DisplayMode(640, 480, 32, 0), new DisplayMode(640, 480, 16, 0), new DisplayMode(640, 480, 8, 0)}; public MultiBufferTest(int numBuffers, GraphicsDevice device) { try { GraphicsConfiguration gc = device.getDefaultConfiguration(); mainFrame = new Frame(gc); mainFrame.setUndecorated(true); mainFrame.setIgnoreRepaint(true); device.setFullScreenWindow(mainFrame); if (device.isDisplayChangeSupported()) { chooseBestDisplayMode(device); } Rectangle bounds = mainFrame.getBounds(); mainFrame.createBufferStrategy(numBuffers); BufferStrategy bufferStrategy = mainFrame.getBufferStrategy(); for (float lag = 2000.0f; lag > 0.00000006f; lag = lag / 1.33f) { for (int i = 0; i < numBuffers; i++) { Graphics g = bufferStrategy.getDrawGraphics(); if (!bufferStrategy.contentsLost()) { g.setColor(COLORS[i]); g.fillRect(0, 0, bounds.width, bounds.height); bufferStrategy.show(); g.dispose(); } try { Thread.sleep((int) lag); } catch (InterruptedException e) { } } } } catch (Exception e) { e.printStackTrace(); } finally { device.setFullScreenWindow(null); } } private static DisplayMode getBestDisplayMode(GraphicsDevice device) { for (int x = 0; x < BEST_DISPLAY_MODES.length; x++) { DisplayMode[] modes = device.getDisplayModes(); for (int i = 0; i < modes.length; i++) { if (modes[i].getWidth() == BEST_DISPLAY_MODES[x].getWidth() && modes[i].getHeight() == BEST_DISPLAY_MODES[x].getHeight() && modes[i].getBitDepth() == BEST_DISPLAY_MODES[x].getBitDepth()) { return BEST_DISPLAY_MODES[x]; } } } return null; } public static void chooseBestDisplayMode(GraphicsDevice device) { DisplayMode best = getBestDisplayMode(device); if (best != null) { device.setDisplayMode(best); } } public static void main(String[] args) { try { int numBuffers = 2; if (args != null && args.length > 0) { numBuffers = Integer.parseInt(args[0]); if (numBuffers < 2 || numBuffers > COLORS.length) { System.err.println("Must specify between 2 and " + COLORS.length + " buffers"); System.exit(1); } } GraphicsEnvironment env = GraphicsEnvironment.getLocalGraphicsEnvironment(); GraphicsDevice device = env.getDefaultScreenDevice(); MultiBufferTest test = new MultiBufferTest(numBuffers, device); } catch (Exception e) { e.printStackTrace(); } System.exit(0); } } 

2.不要这样做,可能会烦恼用户,并且代码缺乏可以改变Native OS分辨率(我的同事在三个屏幕上有超过100个切换,任何改变分辨率来改变切割sizelocation ,结果很简单)

3.使用JLabel for Icons (在适当的LayoutManager放置容器),或者将Icons放到JListJTable ,然后你就不会/不关心某些东西

4.仅使用LayoutManager而不是为屏幕分辨率设置或更改,您可以在屏幕上为Apps start_up设置较小的Size (对于JFrame ),让用户决定她/他的屏幕上的最终Dimmension
