Support for named destinations

Hi,

Named destination are useful in PDF documents as they act as bookmarks to access a specific part of the document (e.g. https://site.com/document.pdf#destination)
See: https://evermap.com/Tutorial_ABM_Destinations.asp

I see that SynPDF supports the TPdfDestination object which works fine from hyperlinks, but it looks like this doesn't create any entries in the Acrobat's "Destinations" pane. I suspect that it isn't supported ? Or perhaps I'm missing some kind of options to export them as named destinations ?

Thanks for your help.

Re: Support for named destinations

Did you try with mORMot 2?

Re: Support for named destinations

I'm not sure that this feature is part of SynPDF 2. Here is a very simple PDF with a named destination, which can be opened at that specific location using the following command line: "C:\Program Files (x86)\Adobe\Acrobat Reader\Reader\AcroRd32.exe" /A "nameddest=MyDest" "C:\Documents\example.pdf"

and for comparison the same one without any named destinations:
