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)

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

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.不要那样做，可能会惹恼用户，并且在缺少代码的情况下可以更改分辨率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快照size，location结果很简单）

3.JLabel使用 for Icons（放入容器中LayoutManager），或放入or ，然后你永远/不关心某事IconsJListJTable

4.只使用LayoutManager而不是定位或更改屏幕分辨率，您可以将屏幕上设置为较小Size（for JFrame）Apps start_up，让用户决定Dimmension她/他的屏幕上的最终
