NReco HTML to PDF turn off Table of Contents generation

Question

I'm trying to set up NReco HTML to PDF generation and having an issue. It generates the PDF but when I open the PDF with adobe reader, it automatically opens the "Bookmarks" side tab consuming quite a bit of screen real estate (about 1/3 of the window).

This is unnecessary, because the PDF is one page long. From what I can tell, this is because the PDF has a table of contents generated by taking the HTML header elements.

I updated my code to attempt to turn of table of contents generation:

        var htmlToPdf = new NReco.PdfGenerator.HtmlToPdfConverter
        {
            GenerateToc = false
        };

        var byteArray = htmlToPdf.GeneratePdf(emailHtmlBody);

        var memStream = new MemoryStream(byteArray);

        return memStream;

but making this change seems to have no effect. Any help with this would be greatly appreciated.

it automatically opens the "Bookmarks" side tab

this is not a table of contents in fact; in terms of wkhtmltopdf (which is internally used by NReco.PdfGenerator) this is called 'outline' and you can disable its generation by H1-H6 tags in the following way:

htmlToPdf.CustomWkHtmlArgs = " --no-outline ";
