Unable to detect barcode in PDF

Post by mdelbene » Thu Jun 27, 2013 3:07 pm

Hi all,
I'm using GDPicture 9.0 and I'm unable to detect barcode in a PDF document with 12 pages.
I splitted the document with you PDF Splitter in 12 distinct documents, and with your sample Barcode Recognition I tried to find the barcode, but not always I get satisfactory results.

I upload the PDF documents "undetectable" (DetectKO_1.pdf, DetectKO_2.pdf, DetectKO_3.pdf) and one document correct (DetectOK.pdf).

Anyone can check these documents and help me?
Thanks in advance.
Michela

Hi,

Our engine indeed detects them but they are seen as corrupted and cannot be read. Even the symbology (which seems to be Code39) cannot be recognized.
To be sure I tried your samples into competitor's engines and I did not find any capable of reading them so my guess is those barcodes are invalid.

Cheers!
