com.google.zxing.NotFoundException for all possibility to decode image containing barcode

Question

i'm using zxing core and integrated with my android app which takes picture. I'm giving bitmap picture input to RGBLuminanceSource. But every time i'm getting NOTFoundException. I do not want to integrate with zxing barcode scanner via intents or CaptureActivity. Here is the code.

       Map<DecodeHintType,Object> HINTS;
       Map<DecodeHintType,Object> HINTS_PURE;
       HINTS = new EnumMap<DecodeHintType,Object>(DecodeHintType.class);
       HINTS.put(DecodeHintType.TRY_HARDER, Boolean.TRUE);
       HINTS.put(DecodeHintType.POSSIBLE_FORMATS, EnumSet.allOf(BarcodeFormat.class));
       HINTS_PURE = new EnumMap<DecodeHintType,Object>(HINTS);
       HINTS_PURE.put(DecodeHintType.PURE_BARCODE, Boolean.TRUE);
       ImageView mImg;

       if (requestCode == SCANNER_REQUEST_CODE && resultCode == RESULT_OK) {  
          // Bitmap bMap = (Bitmap) data.getExtras().get("data");

        Bitmap bMap=BitmapFactory.decodeStream(getContentResolver().openInputStream(outputFileUri));


            // creating binary bitmap from source image


           int length=bMap.getWidth()*bMap.getHeight()*10;
           int[] intArray = new int[bMap.getWidth()*bMap.getHeight()]; 
           bMap.getPixels(intArray, 0, bMap.getWidth(), 0, 0, bMap.getWidth(),                bMap.getHeight());

           //test view to display captured image 
           mImg = (ImageView) findViewById(R.id.imageView);
           mImg.setImageBitmap(bMap);


           // zxing decoding of bitmap image
           Reader reader = new MultiFormatReader();
           String msg=bMap.getWidth()+" * "+bMap.getHeight();
           Log.e("DEBUGGG", msg);
           LuminanceSource source = new RGBLuminanceSource(bMap.getWidth(), bMap.getHeight(),intArray);


           BinaryBitmap bitmap = new BinaryBitmap(new GlobalHistogramBinarizer(source));


           Collection<Result> results = new ArrayList<Result>(1);
           ReaderException savedException = null;



           try {
                  // Look for multiple barcodes
                  MultipleBarcodeReader multiReader = new GenericMultipleBarcodeReader(reader);

                  Result[] theResults = multiReader.decodeMultiple(bitmap, HINTS);
                  if (theResults != null) {
                    results.addAll(Arrays.asList(theResults));
                  }
                } catch (ReaderException re) {
                    re.printStackTrace();
                  savedException = re;
                  re.printStackTrace();
                }


                if (results.isEmpty()) {
                    try {
                      // Look for pure barcode
                      Result theResult = reader.decode(bitmap, HINTS_PURE);
                      if (theResult != null) {
                        results.add(theResult);
                      }
                    } catch (ReaderException re) {
                      savedException = re;
                      re.printStackTrace();

                    }
                  }

                  if (results.isEmpty()) {
                    try {
                      // Look for normal barcode in photo
                      Result theResult = reader.decode(bitmap, HINTS);
                      if (theResult != null) {
                        results.add(theResult);
                      }
                    } catch (ReaderException re) {
                      savedException = re;
                      re.printStackTrace();
                    }
                  }

                  if (results.isEmpty()) {
                    try {
                      // Try again with other binarizer
                      BinaryBitmap hybridBitmap = new BinaryBitmap(new HybridBinarizer(source));
                      Result theResult = reader.decode(hybridBitmap, HINTS);
                      if (theResult != null) {
                        results.add(theResult);
                      }
                    } catch (ReaderException re) {
                      savedException = re;
                      re.printStackTrace();
                    }
                  }
                String barcoderesult="";
                  for (Result result : results) {
                      barcoderesult=barcoderesult+result.getText();
                      Log.e("Debugger","code:  " +result.getText() );
                    }

                //result is empty and notfound exception in logs

Answer 1

I had to create bitmap in rgb from inputstream using bitmap.config.
