How exactly does the method getPixelColor(int x,int y) from the Robot class work? I tried this code fragment:
try
{
Robot robos = new Robot();
}
catch (AWTException e)
{
}
for (int i = 0; i < 100; i++)
robos.getPixelColor(0, 0);
System.out.println("fsadf");
on my PC, which is a core 2 duo, and it took one second or less to execute the print statement. However, when I ran this same code on my laptop, which is a core i3, it took much more time (about 2-3 seconds).
What is the reason behind this? Does it have to do with the screen quality or something like that? How can I solve this problem?
Don’t use the Robot to get the colors pixel by pixel. Use the Robot the create a BufferedImage of the screen. Then you can use the getRGB() method of the BufferedImage to get the int value that represents the color of the pixel. You can then create a Color Object using this int or parse out the red/green/blue values directly.
