Powerpoint Automation Services in SharePoint

Many of organization small or large, uses Microsoft SharePoint Server as a repository for document and  PowerPoint presentations. These businesses all have their particular needs for distributing , updating, and storing their presentations. Microsoft PowerPoint Automation Services is a new feature of Microsoft SharePoint Server 2013 that can help enterprises or business to manage their presentations.

It is a shared service that provides server-side conversion of PowerPoint presentations into other formats like pptx, ppt,  xps, jpg etc. It was designed from the outset to work on servers and can process many presentation files in a reliable and predictable manner.

Using PowerPoint Automation Services, you can convert from the PowerPoint binary file format (.ppt) and the PowerPoint Open XML file format (.pptx) to other formats. For example, you may want to upgrade a batch of PowerPoint 97–2003 files to Open XML presentation files.

All of these classes related to this are contained in Microsoft.Office.Server.PowerPoint.Conversion namespace.

1. Start the Microsoft Visual Studio 2012.

2. Create New Project dialog box, under Installed, expand Templates, expand Visual C#, and then chose Windows.

•   Add a reference to System.Web and Microsoft.SharePoint.
