I'm trying to display the position of the cursor and get the red, blue and green colors of each pixel of an image. My image is on a JPanel. Below is part of my code

imagePanel.addMouseMotionListener(handler);

And then further :

public void mouseMoved(MouseEvent arg0){
System.out.println("cursor at : "+arg0.getX()+" , "+arg0.getY());
}

How can I get the RGB values by adding code in the previous function ?

Why you cannot translate getX() and getY() to image coordinates and get the pixel value?
