// 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
// http://www.pdftron.com/webviewer/licensing.html.
