Welcome,

(You may not understand what I mean in the above if you don't know the platform BUT)
What I need is to convert the image (below), to hex triplet array.

Answer 1

    Path path = Paths.get("... .png");

    System.out.println("Image: " + path);
    try {
        BufferedImage image = ImageIO.read(path.toFile());

        int w = image.getWidth();
        int h = image.getHeight();
        for (int x = 0; x < w; ++x) {
            for (int y = 0; y < h; ++y) {
                int rgb = image.getRGB(x, y);
                System.out.printf("%06X%n", rgb & 0xFF_FF_FF);
            }
            System.out.println();
        }
        System.out.println("Done");

getRGB delivers the color in ARGB format.
