QR code not recognized correctly


I have a scanned document with a QR barcode label (generated by Aspose.Barcode.NET) where the barcode is not recognized correctly (by Aspose.Barcode.NET).

The barcode contains the following string:

SYSLOGPPS:V:2;T:1;F:1;D0:2;D1:319222;D2:BE;D3:1;D4: ;D5: ;DT:0;DA: ;DO:0;TS:20110907T080132;;

I did tests with third-party barcode recognition tools and the code was recognized correctly.

Aspose.Barcode.Recognition (Version 4.4.1) says that it’s found the barcode but just returns a bunch of numbers as codetext:


Using the RotationAdjustmentFilter or the NeatImageFilter does not change the result.

I’ve attached one example PDF, but I’ve had a several cases of this happening.
