How to get the color of a point in a JPanel? [closed]

Answer 1

Draw the content of the panel inside a Graphics2D object created from a BufferedImage and then retrieve the pixel color:

BufferedImage image = new BufferedImage(width, height, BufferedImage.TYPE_4BYTE_ABGR);
Graphics2D g2 = image.createGraphics();
_mainPanel.paint(g2);
image.getColorModel().getRGB(pixel);
g2.dispose();
