Hi mabri, What I want is to read destinations(bookmarks) from PDF documents. Though I would prefer later pdf versions to be my input(later than 1.2) ,I guess even later PDF version could be produced with backward compatibility in mind, so having Destinations with PdfName object.
Having support for destinations with PdfName object would make the class even more complete.

So this isn't for making an entirely new destination, but reading it from a document (which is required to be at least a PDF 1.2 one). Associating a string with a destination and writing it into a document (of at least version PDF 1.2) is done by the (abstract base class) method PdfDocument::AddNamedDestination(const PdfDestination & rDest, const PdfString & rsName) with rDest not constructed from a string PdfObject (and a document), because otherwise the internal PdfObject of the PdfDestination would become a string one, thus that PdfDocument method recording a reference to that string, which isn't conforming to the PDF 1.7 spec clause 12.3.2.3 (allowing only array and some dictionary). I consider this ("otherwise ...") to be a bug in PdfDestination's Init method. According to Note 3 in that clause making a Named Destination with a name object (in PoDoFo: a PdfName), then recorded in the "Dests" entry in the document catalogue, should be used only if backward compatibility is a consideration. So, please inform me about what you (Ali) want: - reading destinations from documents using the PDF 1.1 form of storing them - writing destinations to documents in a form conforming to PDF 1.1 - both - neither (this post contains enough info for you, Ali, to proceed)? I would fix the bug I mentioned anyway if you (PoDoFo developer/s) don't give me convincing reasons for that being no bug. To give you time for this I'll tend to another PoDoFo issue first, I hope today.

Where did you get that from, please? With a better understanding of this I might be able to produce a patch to add what you require (I'm sorry for answering so late), so could you please explain a bit more?

I checked the PoDoFo destination class. It seems to be only supporting string and array. Any reason why this is the case? And is there any way to create named destination with PdfName object (through PoDoFo, or any other methods)?
