Create a ByteArrayInputStream from your byte array and then use ImageIO class to read image from that stream.

InputStream in = new ByteArrayInputStream(bytearray);
BufferedImage image = ImageIO.read(in);

The TexturePaint class can be used to achieve that.

public void paintComponent(Graphics g)
{
   if(paint == null)
   {
      try
      {
          // Create TexturePaint instance the first time

          int height = image.getHeight(this);
          int width = image.getWidth(this);
          bi = (BufferedImage) createImage(width, height);
          Graphics2D biG2d = (Graphics2D) bi.getGraphics();
          biG2d.drawImage(image, 0, 0, Color.black, this);
          paint = new TexturePaint(bi,
             new Rectangle(0,0,width,height));
      }
      catch (Exception ex)
      {
          ex.printStackTrace();
      }
   }

   // Now actually do the painting

   Graphics2D g2d = (Graphics2D) g;
   if(paint != null)
   {
      g2d.setPaint(paint);
      g2d.fill(g2d.getClip());
   }
}

The ImageIO class can be used to write an image as a PNG encoded stream.If you write that stream to a ByteArrayOutputStream then you will end up with a byte array that contains the PNG encoded image.

ByteArrayOutputStream out = new ByteArrayOutputStream();
ImageIO.write(image, "PNG", out);
byte[] imageBytes = out.toByteArray();
