Thank you all for related replies.
I know , using your individual products (especially for .NET) that you can demonstrate adding watermark programmatically on related document format (ex: doc,ppt,xls, pdf....)
But, I just want to know ,using your Aspose Sharepoint related product, what will be your recommended solution for the following requirement :
Client put files into Sharepoint doc lib, and when the files is , thru Sharepoint UI, opened for viewing by authorized users, then I wish that I can ,on the Sharepoint server side, on-the-fly apply watermarking on the document file under request. (Note: the original file is still stored under Sharepoint doc lib, not NOT watermarked)
Is the above requirement be implemented using your Aspose Total for Sharepoint? If not, what will be your suggested solution?
