  1. Hi zeeshan,

    I was reading one of your post on StackOverflow.

    I am working for a client and have to save signature images on the server.

    Do you have the jar file util.ImageUtils ?

    I tried downloading it but can’t find it.

    Thanks for your help.

      import sun.misc.BASE64Encoder;
      import sun.misc.BASE64Decoder;
      import java.awt.image.BufferedImage;
      import javax.imageio.ImageIO;

      public class ImageUtils {

      * Decode string to image
      * @param imageString The string to decode
      * @return decoded image
      public static BufferedImage decodeToImage(String imageString) {

      BufferedImage image = null;
      byte[] imageByte;
      try {
      BASE64Decoder decoder = new BASE64Decoder();
      imageByte = decoder.decodeBuffer(imageString);
      ByteArrayInputStream bis = new ByteArrayInputStream(imageByte);
      image =;
      } catch (Exception e) {
      return image;

      * Encode image to string
      * @param image The image to encode
      * @param type jpeg, bmp, …
      * @return encoded string
      public static String encodeToString(BufferedImage image, String type) {
      String imageString = null;
      ByteArrayOutputStream bos = new ByteArrayOutputStream();

      try {
      ImageIO.write(image, type, bos);
      byte[] imageBytes = bos.toByteArray();

      BASE64Encoder encoder = new BASE64Encoder();
      imageString = encoder.encode(imageBytes);

      } catch (IOException e) {
      return imageString;
