I've an image located at here, Using below code. I am able to contgrol any things on the text that i wanted to write (Eg,signature,Transparent Water mark, Text with differnt Font and size).

 import java.awt.Font;
    import java.awt.Graphics2D;
    import java.awt.Point;
    import java.awt.font.TextAttribute;
    import java.awt.image.BufferedImage;
    import java.io.ByteArrayOutputStream;
    import java.io.FileOutputStream;
    import java.io.IOException;
    import java.net.URL;
    import java.util.HashMap;
    import java.util.Map;

    import javax.imageio.ImageIO;

    public class ImagingTest {

        public static void main(String[] args) throws IOException {
            String url = "http://images.all-free-download.com/images/graphiclarge/bay_beach_coast_coastline_landscape_nature_nobody_601234.jpg";
            String text = "I am appending This text!";
            byte[] b = mergeImageAndText(url, text, new Point(100, 100));
            FileOutputStream fos = new FileOutputStream("so2.png");
            fos.write(b);
            fos.close();
        }

        public static byte[] mergeImageAndText(String imageFilePath,
                String text, Point textPosition) throws IOException {
            BufferedImage im = ImageIO.read(new URL(imageFilePath));
            Graphics2D g2 = im.createGraphics();
            Font currentFont = g2.getFont();
            Font newFont = currentFont.deriveFont(currentFont.getSize() * 1.4F);
            g2.setFont(newFont);


            Map attributes = new HashMap<>();

            attributes.put(TextAttribute.FAMILY, currentFont.getFamily());
            attributes.put(TextAttribute.WEIGHT, TextAttribute.WEIGHT_SEMIBOLD);
            attributes.put(TextAttribute.SIZE, (int) (currentFont.getSize() * 2.8));
            newFont = Font.getFont(attributes);

            g2.setFont(newFont);
            g2.drawString(text, textPosition.x, textPosition.y);
            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            ImageIO.write(im, "png", baos);
            return baos.toByteArray();
        }
    }
