# 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.
