Good, I am trying to join 2 images in java, one of them is a number that is in one image and the other is a black background with a small white hole to put the number, I would like to know if it is possible to place that number number in the hole and then save the image, thanks! Example:
I have this barcode:
And, I have to put it in this image:
We can use BufferedImage to make the combination
BufferedImage biUno= ImageIO.read(new File("uno.png"));
BufferedImage biDos = ImageIO.read(new File("dos.png"));
BufferedImage biResultado = new BufferedImage(1024, 256, BufferedImage.TYPE_INT_ARGB); //suponiendo tamaño de imagen y ARGB que soporta trasparencia
Graphics g = biResultado.getGraphics();
g.drawImage(biUno, 0, 0, null); //se rellena con imagen uno
g.drawImage(biDos, 5, 5, null); //se rellena con imagen dos con un supuesto margen de 5 (habria que ver cual es el real)
ImageIO.write(biResultado, "PNG", new File("resultado.png"));
