RSACryptoServiceProvider rsa = (RSACryptoServiceProvider)pk.PrivateKey; CspParameters cspp = new CspParameters(); cspp.KeyContainerName = rsa.CspKeyContainerInfo

Using the answers in How to merge PDFs into a PDF Portfolio? , I've been able to create an PDF portfolio using iTextSharp. However, using Adobe Acrobat I'm able to create folders, and I'm able to put files in those folders. How do I create folders and how do I put files in those folders in a PDF portfolio using iTextSharp? I've tried using a pdf inspector program to see the differences between a portfolio with and without folders, but I haven't been able to see any. I guess I'm looking in the wrong places EDIT For this specific use case of mine it is actually possible to create the PDF

Summary: How can I reduce the amount of time it takes to convert tifs to pdfs using itextsharp ? Background: I'm converting some fairly large tif's to pdf using C# and itextsharp , and I am getting extremely bad performance. The tif files are approximately 50kb a piece, and some documents have up to 150 seperate tif files (each representing a page). For one 132 page document (~6500 kb) it took about 13 minutes to convert. During the conversion, the single CPU server it was running on was running at 100%, leading me to believe the process was CPU bound. The output pdf file was 3.5 MB. I'm ok
