Answer 1

the problem is if you use this with the bad image
     public static void main(String[] args) {
        Test g = new Test();
           //          bad image
     g.saveImage("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");
       public String saveImage(String codigoEntrada){
          byte[] data=hexStringToByteArray(codigoEntrada);
          try {
               File myFile = new File("C:/imagen.tif");
               FileOutputStream fout = new FileOutputStream(myFile);
               fout.write(data);
               fout.close();
               } catch (IOException e) {
               e.printStackTrace();
     }the image is saved into a file and you can open to see with a external viewer like paint, it's possible this, if the image it's corrupted?
