    Reorder pages

    GroupDocs.Viewer preserves the page order in the source document. Instead, you may reorder pages in the output PDF document.

    To reorder pages, follow these steps:

    1. Instantiate the Viewer object.
    2. Create the PdfViewOptions object.
    3. Call the View method of the Viewer object. Specify the new page order in the last parameters.

    The following code snippet shows how to reorder pages:

    using GroupDocs.Viewer.Options;
using GroupDocs.Viewer;
// ...

using (Viewer viewer = new Viewer("sample.docx"))            
{     
    // Create view options.
    PdfViewOptions viewOptions = new PdfViewOptions();

    // Pass page numbers in the order you want to render them.                
    viewer.View(viewOptions, 2, 1);
}

    Imports GroupDocs.Viewer.Options
Imports GroupDocs.Viewer
' ...

Module Program
    Sub Main(args As String())
        Using viewer As Viewer = New Viewer("sample.docx")
            ' Create view options.
            Dim viewOptions As PdfViewOptions = New PdfViewOptions()

            ' Pass page numbers in the order you want to render them.                
            viewer.View(viewOptions, 2, 1)
        End Using
    End Sub
End Module
