Unable to detect barcode in PDF

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.

Re: Conversion PDF to PDF/A: very large file!

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.

Re: RenderPageToGdPictureImage very slow...

Thanks for the answer.
Can you can explain me what are the differences between the two files that generate this problem?
So I can do some preventive checks to the file I'm processing.

Thank you again.

Re: OCR Individual Pages

Hi Loïc, I read your hint about OCR a Tiff multipage file, but I'm encountering some problems. I try to explain you.

Re: NullReferenceException using RenderPageToGdPictureImage

Hi Loïc,
I installed the newest version (8.3.0.5) and my problem has been solved!
Fixing this error, you have also solved another one, which thrown an InvalidCastException.

Good work! :)
Thank you.
