Barcode Read Error

Post by benoy » Thu Apr 22, 2010 7:16 pm

Hello,

For some reason, when I create the JPG using GdPicture.net , barcode seems much smaller than the actual barcode on the page. Test.jpg is the one I created using your application and the other one is from Adobe Acrobat pro 9-> save as jpg.

test.jpg
test.jpg (7.4 KiB) Viewed 2066 times

Also I am trying to read barcode from PDF files, on the first page. I open the PDF file in the viewer and save the first page as jpg file and open it in the viewer again and scan for barcode.

I believe this process is very slow and inefficient, I need to process 100K + PDFs, please let me know what is the best way to get this done

Can you send me some code samples, please.

Maybe you should adjust output resolution ? If you want investigation from us you can send your file and the code you are using here: http://support.gdpicture.com/index.php? ... rtmentid=4

You re right, it is not the best option. Using our latest GdPicture.NET edition you can do that with very acceptable performances. I will post a code snippet into the code sample section...

Kind regards,
