Usage

From source file:Main.java

    g.setColor(Color.BLUE);//from w  w w  .jav  a2s  .  c  om
    for (int i = 0; i < size; i += 5) {
        g.drawOval(i, i, size - i, size - i);
    }
    g.dispose();

    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    ImageIO.write(image, "png", baos);

    String data = DatatypeConverter.printBase64Binary(baos.toByteArray());
    String imageString = "data:image/png;base64," + data;
    String html = "<html><body><img src='" + imageString + "'></body></html>";
    System.out.println(html);
