ConvertTest - Python

This sample shows how to use PDFNet Convert Add-on (i.e. 'pdftron.PDF.Convert' namespace) for direct, high-quality conversion between PDF, XPS, EMF, SVG, TIFF, PNG, JPEG, and other image formats. The sample also shows how to convert any printable document (e.g. Word, HTML, RTF, MS Office, DXF, DWG, etc) to PDF or XPS using a universal document converter.

# 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-8021-7649FD37FFEEE&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-BE21-27E85E1857B11&displaylang=en
#
# Note: Convert.fromEmf and Convert.toEmf will only work on Windows and require GDI+.
