Java如何获取屏幕像素的颜色？
此处的示例向我们展示了如何获取屏幕上像素的颜色。我们使用该Robot.getPixelColor(intx,inty)方法获得Color像素的。
package org.nhooo.example.awt;
import java.awt.Color;
import java.awt.Robot;
import java.awt.AWTException;
public class ColorPickerDemo {
public static void main(String[] args) {
try {
Robot robot = new Robot();
//20、20处的像素颜色信息
Color color = robot.getPixelColor(20, 20);
//打印像素颜色的RGB信息
System.out.println("Red = " + color.getRed());
System.out.println("Green = " + color.getGreen());
System.out.println("Blue = " + color.getBlue());
} catch (AWTException e) {
e.printStackTrace();
}
}
}
