WebViewerConvertTest - Java

These samples shows how to use integrate PDFNet WebViewer into any HTML5, Silverlight, or Flash web application. The sample is using 'pdftron.PDF.Convert.ToXod()' to convert/stream PDF, XPS, MS Office, RTF, HTML and other document formats to WebViewer 'pdftron.PDF.Convert.ToXod()' is an optional Add-On to the Core SDK and is part of PDFNet WebViewer Publishing Platform.

// The following sample illustrates how to convert PDF, XPS, image, MS Office, and 
// other image document formats to XOD format.
//
// Certain file formats such as PDF, generic XPS, EMF, and raster image formats can 
// be directly converted to XOD. Other formats such as MS Office 
// (Word, Excel, Publisher, Powerpoint, etc) can be directly converted via interop. 
// These types of conversions guarantee optimal output, while preserving important 
// information such as document metadata, intra document links and hyper-links, 
// bookmarks etc. 
//
// In case there is no direct conversion available, PDFNet can still convert from 
// any printable document to XOD using a virtual printer driver. To check 
// if a virtual printer is required use Convert::RequiresPrinter(filename). In this 
// case the installing application must be run as administrator. The manifest for this 
// sample specifies appropriate the UAC elevation. The administrator privileges are 
// not required for direct or interop conversions. 
//
// Please note that PDFNet Publisher (i.e. 'pdftron.PDF.Convert.ToXod') is an
// optionally licensable add-on to PDFNet Core SDK. For details, please see
// http://www.pdftron.com/webviewer/licensing.html.
