If the annotation is a "Link" annotation then the GetAnnotDest function is used to get the destination (the DestID). If the DestID is zero it means there is no destination only an action for that Link annotation.

So this means, if DestID is a positive number then the GetDestPage function is used to get the page that the destination points to, but if the DestID is zero then the GetAnnotIntProperty is used to get the action's page.

Another way of doing it for annotations with actions is using these functions:

GetAnnotActionID

GetActionDest

GetDestPage

In addition, for retrieving the destination zoom and location, the GetDestValue function can be used.

If you're working with named destinations then use the GetNamedDestination function. It locates the named destination with the specified name and returns a DestID that can be used with the GetDestPage, GetDestType and GetDestValue functions.

Thank you very much for your reply.

The key is how can I get the specified name where a certain annotation links?

I still need your help.

Hello Rowan

Is there a "SetNamedDestination" to give a name to an outline link (bookmark) or an annotation?

I wish to retrieve a page in a PDF document not by the pageNumber, but by a named destination. So I have to build such a Dests outline tree :
1 0 obj
<</Type/Catalog
/Names 2 0 R
>>
endobj

2 0 obj
<</Dests 3 0 R
>>
endobj

3 0 obj
<</Names [
(intro) 15 0 R
(conclusion) 16 0 R
(contact) 17 0 R
]
>>

Is it possible (and how) to do it?

Many thanks for your reply.

Hi gege,

There isn't currently a SetNamedDestination function, but in the beta release that we're releasing tonight we've added some new functions that let you add named destinations to documents.

We'll post it on http://www.quickpdflibrary.com/blog/ - our blog within the next 12 hours.

Cheers,

- Rowan.
