Exemplos

O exemplo seguinte mostra o uso da AnnotationDocumentPaginator classe.

PrintDialog prntDialog = new PrintDialog();
if ((bool)prntDialog.ShowDialog())
{
    // XpsDocumentWriter.Write() may change the current
    // directory to "My Documents" or another user selected
    // directory for storing the print document.  Save the
    // current directory and restore it after calling Write().
    string docDir = Directory.GetCurrentDirectory();

    // Create and XpsDocumentWriter for the selected printer.
    XpsDocumentWriter xdw = PrintQueue.CreateXpsDocumentWriter(
                                        prntDialog.PrintQueue);

    // Print the document with annotations.
    try
    {
        xdw.Write(_annotHelper.GetAnnotationDocumentPaginator(
            _xpsDocument.GetFixedDocumentSequence()));
    }
    catch (PrintingCanceledException)
    {
        // If in the PrintDialog the user chooses a file-based
        // output, such as the "MS Office Document Image Writer",
        // the user confirms or specifies the actual output
        // filename when the xdw.write operation executes.
        // If the user clicks "Cancel" in the filename
        // dialog a PrintingCanceledException is thrown
        // which we catch here and ignore.
        // MessageBox.Show("Print output cancelled");
    }

    // Restore the original document directory to "current".
    Directory.SetCurrentDirectory(docDir);
