Examples

The following example shows how to obtain an IXpsFixedPageReader collection from an IXpsFixedDocumentReader. The sample also shows how to use the fixed-page reader to add a new StoryFragment that defines the document structure of the page.

ShowStatus("   Getting FixedDocumentSequenceReader.");
IXpsFixedDocumentSequenceReader fixedDocSeqReader =
    xpsDocument.FixedDocumentSequenceReader;

ShowStatus("   Getting FixedDocumentReaders.");
ICollection<IXpsFixedDocumentReader> fixedDocuments =
    fixedDocSeqReader.FixedDocuments;

ShowStatus("   Getting FixedPageReaders.");
IEnumerator<IXpsFixedDocumentReader> enumerator =
    fixedDocuments.GetEnumerator();
enumerator.MoveNext();
ICollection<IXpsFixedPageReader> fixedPages =
    enumerator.Current.FixedPages;

// Add a document structure to each fixed page.
int i = 0;
foreach (IXpsFixedPageReader fixedPageReader in fixedPages)
{
    XpsResource pageStructure;
    ShowStatus("   Adding page structure resource:\n       '" +
                       Filename(_fixedPageStructures[i]) + "'");
    try
    {   // Add a new StoryFragment to hold the page structure.
        pageStructure = fixedPageReader.AddStoryFragment();
    }
    catch (System.InvalidOperationException)
    {
        MessageBox.Show(xpsUnstructuredFile +
            "\n\nDocument structure cannot be added.\n\n" +
            Filename(xpsUnstructuredFile) + " might already " +
            "contain an existing document structure.",
            "Cannot Add Document Structure",
            MessageBoxButton.OK, MessageBoxImage.Error);
        break;
    }

    // Copy the page structure to the new StoryFragment.
    WriteResource(pageStructure, _fixedPageStructures[i++]);
}

ShowStatus("   Saving and closing the new document.\n");
xpsDocument.Close();

ShowStatus("   Getting FixedDocumentSequenceReader.")
Dim fixedDocSeqReader As IXpsFixedDocumentSequenceReader = xpsDocument.FixedDocumentSequenceReader

ShowStatus("   Getting FixedDocumentReaders.")
Dim fixedDocuments As ICollection(Of IXpsFixedDocumentReader) = fixedDocSeqReader.FixedDocuments

ShowStatus("   Getting FixedPageReaders.")
Dim enumerator As IEnumerator(Of IXpsFixedDocumentReader) = fixedDocuments.GetEnumerator()
enumerator.MoveNext()
Dim fixedPages As ICollection(Of IXpsFixedPageReader) = enumerator.Current.FixedPages


' Add a document structure to each fixed page.
Dim i As Integer = 0
For Each fixedPageReader As IXpsFixedPageReader In fixedPages
    Dim pageStructure As XpsResource
    ShowStatus("   Adding page structure resource:" & vbLf & "       '" & Filename(_fixedPageStructures(i)) & "'")
    Try
        pageStructure = fixedPageReader.AddStoryFragment()
    Catch e2 As InvalidOperationException
        System.Windows.MessageBox.Show(xpsUnstructuredFile & vbLf & vbLf & "Document structure cannot be added." & vbLf & vbLf & Filename(xpsUnstructuredFile) & " might already " & "contain an existing document structure.",
                        "Cannot Add Document Structure",
                        MessageBoxButton.OK,
                        MessageBoxImage.Error)
        Exit For
    End Try

    ' Copy the page structure to the new StoryFragment.
    WriteResource(pageStructure, _fixedPageStructures(i))
    i += 1
Next fixedPageReader

ShowStatus("   Saving and closing the new document." & vbLf)
xpsDocument.Close()
