    viewOptions.PdfOptimizationOptions = new PdfOptimizationOptions();
    viewOptions.PdfOptimizationOptions.RemoveAnnotations = true;

    viewer.View(viewOptions);
}
Imports GroupDocs.Viewer
Imports GroupDocs.Viewer.Options
' ...

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