''' </summary>
''' <param name="inPdfFilename">The input PDF filename.</param>
''' <param name="outPdfFilename">The output PDF filename.</param>
Public Shared Sub RemoveUnsusedResources(inPdfFilename As String, outPdfFilename As String)
    ' create compressor with empty compression settings
    Dim compressor As Vintasoft.Imaging.Pdf.Processing.PdfDocumentCompressorCommand = Vintasoft.Imaging.Pdf.Processing.PdfDocumentCompressorCommand.CreateEmptyCompressor()

    ' specify that compressor must remove duplicate resources from PDF document
    compressor.RemoveDuplicateResources = True
    ' specify that compressor must remove unused names resources from PDF document
    compressor.RemoveUnusedNamedResources = True
    ' specify that compressor must remove unused names from PDF document
    compressor.RemoveUnusedNames = True
    ' specify that compressor must remove unused pages from PDF document
    compressor.RemoveUnusedPages = True
    ' specify that compressor must remove invalid bookmarks from PDF document
    compressor.RemoveInvalidBookmarks = True
    ' specify that compressor must remove invalid links from PDF document
    compressor.RemoveInvalidLinks = True

    ' compress PDF document
    compressor.Compress(inPdfFilename, outPdfFilename)
End Sub


/// <summary>
/// Removes unused and duplicated resources in the PDF document.
/// </summary>
/// <param name="inPdfFilename">The input PDF filename.</param>
/// <param name="outPdfFilename">The output PDF filename.</param>
public static void RemoveUnsusedResources(string inPdfFilename, string outPdfFilename)
{
    // create compressor with empty compression settings
    Vintasoft.Imaging.Pdf.Processing.PdfDocumentCompressorCommand compressor =
       Vintasoft.Imaging.Pdf.Processing.PdfDocumentCompressorCommand.CreateEmptyCompressor();

    // specify that compressor must remove duplicate resources from PDF document
    compressor.RemoveDuplicateResources = true;
    // specify that compressor must remove unused names resources from PDF document
    compressor.RemoveUnusedNamedResources = true;

    compressor.RemoveInvalidBookmarks = true;
