Bookmarks / outline extraction #4

Hi, I'm able to add an outline to a PDF using pdfmarks, as described here.

For example:

pdfmarks:

[ /Count -3
    /Title (chapter 1)
    /Page 1
    /OUT pdfmark
[ /Title (chapter 1.1)
  /Page 3
  /OUT pdfmark
[ /Count -1
    /Title (chapter 1.2)
    /Page 4
    /OUT pdfmark
[ /Title (chapter 1.2.1)
  /Page 4
  /OUT pdfmark
[ /Count -1
    /Title (chapter 1.3)
    /Page 8
    /OUT pdfmark
[ /Title (chapter 1.3.1)
  /Page 9
  /OUT pdfmark
[ /Title (chapter 2)
  /Page 11
  /OUT pdfmark
[ /Title (chapter 3)
  /Page 30
  /OUT pdfmark
[ /Title (chapter 4)
  /Page 35
  /OUT pdfmark
[ /Title (chapter 5)
  /Page 40
  /OUT pdfmark

and:

gs -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile={output_file}  ./pdfmarks {input_file}

will result in an outline like:

Is this program able to extract this type of pdfmarks?

I tried as described in the README, but I got only:

% Extract PDFmark 1.1.1 (with poppler-cpp)
% https://github.com/trueroad/extractpdfmark

[ /PageMode /UseNone /DOCVIEW pdfmark

As described at the beginning of README.md, Extract PDFmark extracts page mode and named destinations. It cannot extract other things like outlines or bookmarks.

Is it possible to add this functionality?
