// The following sample illustrates how to use the PDF::Convert utility class to convert 
// documents and files to PDF, XPS, SVG, or EMF.
//
// Certain file formats such as XPS, EMF, PDF, and raster image formats can be directly 
// converted to PDF or XPS. Other formats are converted using a virtual driver. To check 
// if ToPDF (or ToXPS) require that PDFNet printer is installed use Convert::RequiresPrinter(filename). 
// The installing application must be run as administrator. The manifest for this sample 
// specifies appropriate the UAC elevation.
//
// Note: the PDFNet printer is a virtual XPS printer supported on Vista SP1 and Windows 7.
// For Windows XP SP2 or higher, or Vista SP0 you need to install the XPS Essentials Pack (or 
// equivalent redistributables). You can download the XPS Essentials Pack from:
//		http://www.microsoft.com/downloads/details.aspx?FamilyId=B8DCFFDD-E3A5-44CC-8021-7649FD37FFEE&displaylang=en
// Windows XP Sp2 will also need the Microsoft Core XML Services (MSXML) 6.0:
// 		http://www.microsoft.com/downloads/details.aspx?familyid=993C0BCF-3BCF-4009-BE21-27E85E1857B1&displaylang=en
//
// Note: Convert.FromEmf and Convert.ToEmf will only work on Windows and require GDI+.
//
// Please contact us if you have any questions.
