18	/// The following sample illustrates how to convert PDF, XPS, image, MS Office, and 
19	/// other image document formats to XOD format.
20	/// 
21	/// Certain file formats such as PDF, generic XPS, EMF, and raster image formats can 
22	/// be directly converted to XOD. Other formats such as MS Office 
23	/// (Word, Excel, Publisher, Powerpoint, etc) can be directly converted via interop. 
24	/// These types of conversions guarantee optimal output, while preserving important 
25	/// information such as document metadata, intra document links and hyper-links, 
26	/// bookmarks etc. 
27	/// 
28	/// In case there is no direct conversion available, PDFNet can still convert from 
29	/// any printable document to XOD using a virtual printer driver. To check 
30	/// if a virtual printer is required use Convert::RequiresPrinter(filename). In this 
31	/// case the installing application must be run as administrator. The manifest for this 
32	/// sample specifies appropriate the UAC elevation. The administrator privileges are 
33	/// not required for direct or interop conversions. 
34	/// 
35	/// Please note that PDFNet Publisher (i.e. 'pdftron.PDF.Convert.ToXod') is an
36	/// optionally licensable add-on to PDFNet Core SDK. For details, please see
37	/// https://apryse.com/pricing
