Thanks again for your response. I will review the samples you sent and get back if I have any more questions re watermarking.
On a side note when I run the demo on my localhost I can convert large PDF files to SWF without issue. I can also convert large files when running through your demo link
However then I try and convert PDFs greater then one page on my web server (IIS 6.0, ASP.NET 2.0) it errors out with: Object reference not set to an instance of an object.
I have both Aspose.Flash.dll and Aspose.Pdf.Kit.dll referenced in the bin (same copies as on my local machine where it works).
It seems to fail on this line: converter.SaveAsTIFF(ms);
Code on web page is as above in previous thread.

Are you aware of anything that may be causing this?
