XAML2PDFTest - C#

This example shows how to use PDFNet Convert Add-on (i.e. 'pdftron.PDF.Convert' namespace) to dynamically generate PDF or XPS directly from a FlowDocument, XAML, or WPF. Converting XAML/FlowDocument to PDF is not only easy, but is also very flexible in terms of how content is paginated and flowed into a fixed document such as PDF or XPS.

    /// This sample shows how use pdftron.Xaml.Convert to convert .xaml files 
    /// into PDF documents with control over headers and footers, main body placement,
    /// and column widths.  Pagination is controlled by specifying the page size and 
    /// body size (margins) and all pages are appended to a PDFDoc which can then be
    /// further manipulated using the PDFNet API.
    /// 
    /// Three types of XAML objects are convertible using pdftron.Xaml.Convert:
    /// - FlowDocument's which describe content that is reflowable from page to page
    /// - FixedDocument's which describe content that has been placed on a fixed page
    /// - Blocks such as Canvas, RichTextBox, Section etc which can be wrapped or inserted 
    ///     directly into a FlowDocument
    ///     
    /// This sample has three example uses of pdftron.Xaml.Convert:
    /// - CreateXamlFlowDocumentFromCanvas() demonstrates how to read in a Canvas
    ///   described in a .xaml file and convert it to PDF.
    /// - CreateXamlTableAndConvert() demonstrates how to programmatically create
    ///   a FlowDocument with a table, and then convert it to PDF as a single column
    ///   document.
    /// - ConvertXamlFlowDocumentsFromFiles() demonstrates how to define functions to
    ///   create page headers and footers.
    ///   
    /// Limitations:
    /// Requires Microsoft .NET 3.5
    /// 
    /// There are many Xaml classes that cannot be added to FlowDocument or FixedDocuments and
    /// therefore this sample converter cannot convert Page, Window or Frame objects.
