How can i get a larger area of pixels for the Robot.getPixelColor(x, y) method?
import java.awt.Color;
import java.awt.Robot;

public class Colour
{
    int    x, y;
    int    n    = 0;
    int    m    = 0;
    int    i    = 0;

    public Colour()
    {
        try
        {
            Robot robot = new Robot();
            Color targetColor = new Color(255, 25, 255);
            Color color = robot.getPixelColor(n, n);

            while (color.getRGB() != targetColor.getRGB() && i != 1000)
            {
                color = robot.getPixelColor(n, n);
                System.out.println("color = " + color);
                n++;
                i++;

                if (color.getRGB() == targetColor.getRGB())
                {
                    i = 1000;
                    System.out.println("colour found" + n + " " + n);
                }
            }
        }
        catch (Exception e)
        {
        }
    }

    public static void main(String[] args)
    {
        Colour color = new Colour();
    }
}

for(int i=0;i<=1000;i++){
    for(int j=0;j<=1000;j++){
        color = robot.getPixelColor(i, j);
        System.out.println("color = " + color);

        if(color.getRGB() == targetColor.getRGB()){
            System.out.println("colour found" + i + " " + j);
            i=1000;
            break;
        }
    }
}
