Thanks for your response.

I tested your code, and it working fine for reading bar-code values.

But it is also returning values where no bar-code present.

Hi Chinnu,

I used syncfusion library for reading barcode in pdf file, I'm able to read barcode created and pasted in file but i'm not able to read barcode from Pdf documents which have barcode printed on them and scanned through scanner.

Kindly find attached sample document.

Thanks and Regards,

Pravin Chopade

Hi Pravin, 

Thank you for your interest in Syncfusion Products. 

Our Barcode scanner rely on ZXing barcode decoder for detecting Barcode. On our analysis, ZXing could not detect the Barcode in the specific PDF, we have also tried with sharpening the input but still the Barcode is not detectable. As this issue occurs with the ZXing, we could not proceed further to fix this issue. 

Please let us know if you have any concerns.

hello, for a complete integration of your library in our software we would need a signed dll. Where can we find the dll "Syncfusion.BarcodeReader.OPX" digitally signed? Thanks
