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. 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:...

Re: StackOverflowException using CreateGdPictureImageFromFil
Hi Loïc,
I have this error in a procedure called by a web service.
It seems appear with .doc files.
I can try to create a simple application with the same code to reproduce the problem.
Thanks for your attention.

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.
