	/// <summary>
	/// The following sample illustrates how to convert PDF, XPS, image, MS Office, and 
	/// other image document formats to XOD format.
	/// Certain file formats such as PDF, generic XPS, EMF, and raster image formats can 
	/// be directly converted to XOD. Other formats such as MS Office 
	/// (Word, Excel, Publisher, Powerpoint, etc) can be directly converted via interop. 
	/// These types of conversions guarantee optimal output, while preserving important 
	/// information such as document metadata, intra document links and hyper-links, 
	/// bookmarks etc. 
	/// In case there is no direct conversion available, PDFNet can still convert from 
	/// any printable document to XOD using a virtual printer driver. To check 
	/// if a virtual printer is required use Convert::RequiresPrinter(filename). In this 
	/// case the installing application must be run as administrator. The manifest for this 
	/// sample specifies appropriate the UAC elevation. The administrator privileges are 
	/// not required for direct or interop conversions. 
	/// Please note that PDFNet Publisher (i.e. 'pdftron.PDF.Convert.ToXod') is an
	/// optionally licensable add-on to PDFNet Core SDK. For details, please see
	/// </summary>
