How to define the filter for the PDF file in iTextSharp?

[my4color]

Hello everyone,

we are creating the PDF file using the iTextSharp.
After creating that file we are using the Acrobat's iFilter for extracting text from that PDF file.

But we get the exception "No Filter defined for the PDF file",

So how can we define the Filter for PDF file, so that iFilter can extract it's text.

Thanks in advance,

Jay.

Hello,

I am getting problem due to following reason, that i found, so posting this information for sharing the knowledge.

After working with this wrapper for IFilter.I found that i get the exception due to threading.

When the object of this class is initialize during one thread, and after that if any another thread tries to initialize the object of that class than it creates a exception.

I donot know how this wrapperis designed around the DLL, but if possible it need to release the resources when the thread is going to aborted or completed.

By the way this is what I found, if it is wrong than please point me.
Thanks again.

Best Reagrds,
Jay.
