Hi all,
I'm using GDPicture 9.0 and I'm unable to detect barcode in a PDF document from my C# application.

I have also tried to use you sample but the results are the same.

I upload the file: can you try and tell me where is the problem?

Thanks in advance.
Michela.

Hi Loïc,
thank you for your answer.
The file I'm trying to convert is already in black/white, but if you have any suggestions or any sample code to obtain more compression I can try it.

Regards.

Thank you again.

Hi all, I'm using C # applications, where I added reference to GdPicture rel. 8.5 component. My dll performs OCR of a PDF file, saved locally in c:\Windows\Temp folder on the server. My project contains also the referenced dll GdPicture, but only the 32-bit version, because my application runs x86. ...

Hi Loïc, I read your hint about OCR a Tiff multipage file, but I'm encountering some problems. I try to explain you. I'm using the sample C# project installed in GdViewerSamplesv8\OCR\ with some changes. I open a Tiff multipage, then I loop on the pages and I call OCR on each page. This is the code:...

Hi Loïc,

Hi Loïc,
I installed the newest version (8.3.0.5) and my problem has been solved!

Good work!
Thank you.
