Java

I have a PNG image 200x100 pixels. And in it I need to write an array of pixels 200x100 (values ​​​​with a certain rgb color). How can this be implemented?

Answer 1

public static void main(String[] args) throws IOException {
    
    BufferedImage png = ImageIO.read(new File("image.png"));
    
    Color color = new Color(0, 0, 0);
    
    png.setRGB(2, 2, color.getRGB());
    
    ImageIO.write(png, "png", new File("image.png"));

  }
