I asked a version of this question earlier, but I'm in need of other solutions, so this is a more pointed question. I'm in need of a server-based solution for converting ppt files to pdf files. This solution can either sit on the current web server as a console command-triggered service, it can be integrated into the C# code of the web all, or it can be it's own server. It also can't be based off of Libreoffice or Openoffice, as those two have problems converting SmartArt. I'm currently using Libreoffice. I've tried Powerpoint console commands combined with a PDF driver but I can't get that to work from C#. I've tried a .vbs script, but that briefly opens the powerpoint window.
