I am looking for a way to insert PresentationML and / or DrawingML into an open PowerPoint 2007/2010 presentation using the Open XML SDK or simply System.IO.Packaging. There is an article about doing this using Word , but in this example it uses a procedure Range.XMLin the Word Object Model, which I cannot find an equivalent in the PowerPoint Object Model.
The reason I want to do this is to keep in mind that the PowerPoint client does not support editing, but what Open XML does (and as a result, PowerPoint displays it). I want to install this myself through managed-addin (VSTO) in an open presentation. An example is text underlining (not that I'm looking for this, but this is an example) - in PowerPoint you cannot make text underline a picture <a:blip/>, but in Open XML you can.
Does anyone know how to do this?
