Hi, Actuallu I tried this code but I got following error "Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: Coordinate out of bounds!"
even if I minimize image size but it shows me same error...
import java.io.*;
import java.awt.*;
import javax.imageio.ImageIO;
import java.awt.image.BufferedImage;
public class GetPixelColor
  public static void main(String args[]) throws IOException{
    File file= new File("C:\\LVII-176_01_l.jpg");
    BufferedImage image = ImageIO.read(file);
    // Getting pixel color by position x=100 and y=40
    int height=image.getHeight();
    int width=image.getWidth();
    System.out.println("Height=>"+height);
    System.out.println("width=>"+width);
   // int clr=  image.getRGB(height,width);
    int clr=  image.getRGB(width,height);
    int  red   = (clr & 0x00ff0000) >> 16;
    int  green = (clr & 0x0000ff00) >> 8;
    int  blue  =  clr & 0x000000ff;
    System.out.println("Red Color value = "+ red);
    System.out.println("Green Color value = "+ green);
    System.out.println("Blue Color value = "+ blue);
}
