# The following sample illustrates how to use the PDF::Convert utility class to convert 
# documents and files to PDF, XPS, or SVG, or EMF. The sample also shows how to convert MS Office files 
# using our built in conversion.
#
# Certain file formats such as XPS, EMF, PDF, and raster image formats can be directly 
# converted to PDF or XPS.
