decode hints combination

[junfei wang]

I think I have to open a brand new thread about my problem so far.

https://docs.google.com/file/d/0B6mDg0MzJ8fpVGlCWmx0aktqeEE/edit

the link above is the image I want to decode. This is a random byte array encoded with ISO-8859-1. When I used the barcode scanner app, it has no problem;

when I want to decode it with my own app, it throws notfound exception.

This is my code for decoding: 

                           LuminanceSource source = new PlanarYUVLuminanceSource(data,640,480,0,0,640,480,false);

   bmtobedecoded = new BinaryBitmap(new HybridBinarizer(source));

   Map<DecodeHintType,Object> mp=new HashMap<DecodeHintType, Object>();

   mp.put(DecodeHintType.CHARACTER_SET, "ISO-8859-1");

   mp.put(DecodeHintType.PURE_BARCODE, true);

    //Vector formats = new Vector();

   // formats.addElement(BarcodeFormat.QR_CODE);

   // mp.put(DecodeHintType.POSSIBLE_FORMATS, formats);

   // mp.put(DecodeHintType.TRY_HARDER, true);

  // mp.put(DecodeHintType.ASSUME_CODE_39_CHECK_DIGIT, true);

   qrr.setHints(mp);

   try {

result= qrr.decodeWithState(bmtobedecoded);

// Log.i("123","decoded byte array "+java.util.Arrays.toString(result.getRawBytes()));

} catch (NotFoundException e) {

Log.i("123","not found");

e.printStackTrace();

}  

I can't see any difference between my code with the one in Barcode Scanner app, can someone help me with this issue?

btw, qrr is just a MultiFormatReader, initially I used QRCodeReader, then I decided to follow the barcode scanner app.
