title: Parameter 'Nameddest' in PDF files
body: <p>I'd like to open a PDF at a specific bookmark/outline location by means of the nameddest parameter.
  For instance, the following link opens a PDF at the bookmark "Contents":</p>
  
  <p><a href="https://www.adobe.com/content/dam/acom/en/devnet/acrobat/pdfs/pdf_open_parameters.pdf#nameddest=Contents" rel="nofollow noreferrer">https://www.adobe.com/content/dam/acom/en/devnet/acrobat/pdfs/pdf_open_parameters.pdf#nameddest=Contents</a></p>
  
  <p>The following link opens the file at the bookmark "Parameters":
  <a href="https://www.adobe.com/content/dam/acom/en/devnet/acrobat/pdfs/pdf_open_parameters.pdf#nameddest=Parameters" rel="nofollow noreferrer">https://www.adobe.com/content/dam/acom/en/devnet/acrobat/pdfs/pdf_open_parameters.pdf#nameddest=Parameters</a></p>
  
  <p>The following link also opens the file at the bookmark "Parameters":
  <a href="https://www.adobe.com/content/dam/acom/en/devnet/acrobat/pdfs/pdf_open_parameters.pdf#nameddest=G4.1501771" rel="nofollow noreferrer">https://www.adobe.com/content/dam/acom/en/devnet/acrobat/pdfs/pdf_open_parameters.pdf#nameddest=G4.1501771</a> </p>
  
  <p><strong>From the example above, why nameddest=G4.150177?</strong></p>
  
  <p>If I already have a PDF file how can I retrieve all the possible values for the nameddest parameter?</p>
  
  <p>Is there a section in the PDF file where I can retrieve all the bookmarks so that I can use them in the nameddest parameter?</p>
  
  <p>I know that the names displayed in the bookmark section are can be different than their actual destinition (PDF specification <a href="https://www.adobe.com/content/dam/acom/en/devnet/acrobat/pdfs/pdf_open_parameters.pdf#nameddest=G4.1501771" rel="nofollow noreferrer">https://www.adobe.com/content/dam/acom/en/devnet/acrobat/pdfs/pdf_open_parameters.pdf#nameddest=G4.1501771</a>)</p>
