[Jaspreet Singh]

From the above two image only one with flip is decoded but the straight one does not decodes.Please help me what should i do.It is both encoded and decoded using zxing.

Could you show your code? Did you set to true the AutoRotate var when initializing the BarcodeReader?

Mirror-imaged QR codes are not valid. One works, the other one doesn't, as expected. Only one is a correct barcode.

Those two barcodes are the exact same code, no mirror. The second one is first one rotated to the left 90 degrees. I can scan both.

LuminanceSource source = new BufferedImageLuminanceSource(bufferedImage);
BinaryBitmap bitmap = new BinaryBitmap(new GlobalHistogramBinarizer(source));
Reader mReader = new MultiFormatReader();
GenericMultipleBarcodeReader reader = new GenericMultipleBarcodeReader(mReader);
results = reader.decodeMultiple(bitmap, hints);
I am using above code.
And both are scanning from any android app but not through the java application and also not from the online zxing decoder.

I would rather use this instead:

var barcodeReader = new ZXing.BarcodeReader();
barcodeReader.AutoRotate = true;

The code you are using is for reading several codes in one single file, do you really need this or you will only read one code by file? I didn't try it but I guess you cannot use the property barcodeReader.AutoRotate = true; for reading multiple codes in a single file.

Sean could help you better in this, I think he misunderstood your question.
