/// font or image resources.</remarks>
public void Create(XpsDocument xpsDocument)
{
// Create the document sequence
IXpsFixedDocumentSequenceWriter docSeqWriter =
xpsDocument.AddFixedDocumentSequence();
// Create the document
IXpsFixedDocumentWriter docWriter = docSeqWriter.AddFixedDocument();
// Create the Page
IXpsFixedPageWriter pageWriter = docWriter.AddFixedPage();
// Get the XmlWriter
XmlWriter xmlWriter = pageWriter.XmlWriter;
// Write the mark up according the XPS Specifications
BeginFixedPage(xmlWriter);
AddGlyphRun(pageWriter, xmlWriter,
"This is a photo of the famous Notre Dame in Paris",
16, 50, 50, @"C:\Windows\fonts\arial.ttf");
AddImage(pageWriter, xmlWriter,
"ParisNotreDame.jpg", XpsImageType.JpegImageType,
100, 100, 600, 1100 );
// End the page.
EndFixedPage( xmlWriter );
// Close the page, document, and document sequence.
pageWriter.Commit();
docWriter.Commit();
docSeqWriter.Commit();
_fontDictionary.Clear();
}// end:Create()
