byte []到bufferedImage的转换为null

Question

I am trying to convert byte[] array to buffered image so than i can resize the image..but problem is conversion always turned into null.here is my code..

 ByteArrayInputStream bais = new ByteArrayInputStream(user.getUser_image());
 //Here user.getUser_image() returns byte[] returned from server..
 try {
      BufferedImage image = ImageIO.read(bais);
      System.out.println("============><================"+image);//Here it prints null
      BufferedImage scaledImage = Scalr.resize(image,48);
 }
 .....and so on

Answer 1

It means that the ImageIO class is not able to select an appropriate ImageReader. The purpose of this could be corrupted byte array or unsupported image type. Try to debug it.
