    溫馨提示:易賢網(wǎng)小編為您整理了“java實(shí)現(xiàn)屏幕取色”,方便廣大網(wǎng)友查閱!

    代碼1。在屏幕上輸出當(dāng)前鼠標(biāo)所在的屏幕顏色。

    import java.awt.*;

    public class PickColor {

    public static void main(String[] args) {

    PickColor pc = new PickColor();

    Color color = pc.pickColor();

    System.out.println("color = "+color);

    }

    public Color pickColor() {

    Color pixel = new Color(0,0,0);

    Robot robot = null;

    Point mousepoint;

    int R,G,B;

    // MouseInfo mouseinfo = new MouseInfo();

    try {

    robot = new Robot();

    } catch (AWTException e) {

    e.printStackTrace();

    System.exit(1);

    }

    mousepoint = MouseInfo.getPointerInfo().getLocation();

    pixel = robot.getPixelColor(mousepoint.x,mousepoint.y);

    R = pixel.getRed();

    G = pixel.getGreen();

    return pixel;

    }

    }

    代碼2。使用一個(gè)GUI,輸出當(dāng)前鼠標(biāo)所在的屏幕顏色,并改變GUI的背景色。
