10// The following sample illustrates how to use the PDF::Convert utility class to convert 
11// documents and files to PDF, XPS, SVG, or EMF.
12//
13// Certain file formats such as XPS, EMF, PDF, and raster image formats can be directly 
14// converted to PDF or XPS. Other formats are converted using a virtual driver. To check 
15// if ToPDF (or ToXPS) require that PDFNet printer is installed use Convert::RequiresPrinter(filename). 
16// The installing application must be run as administrator. The manifest for this sample 
17// specifies appropriate the UAC elevation.
18//
19// Note: the PDFNet printer is a virtual XPS printer supported on Vista SP1 and Windows 7.
20// For Windows XP SP2 or higher, or Vista SP0 you need to install the XPS Essentials Pack (or 
21// equivalent redistributables). You can download the XPS Essentials Pack from:
22//     http://www.microsoft.com/downloads/details.aspx?FamilyId=B8DCFFDD-E3A5-44CC-8021-7649FD37FFEE&displaylang=en
23// Windows XP Sp2 will also need the Microsoft Core XML Services (MSXML) 6.0:
24//     http://www.microsoft.com/downloads/details.aspx?familyid=993C0BCF-3BCF-4009-BE21-27E85E1857B1&displaylang=en
25//
26// Note: Convert.FromEmf and Convert.ToEmf will only work on Windows and require GDI+.
27//
28// Please contact us if you have any questions.
