I am trying to find all of the relevant information about links within a tagged PDF that either go to a place in the same document or go to a url. I tried traversing the tree of StructElements starting from the StructTreeRoot like this: Catalog *catalog = doc->getCatalog(); StructTreeRoot *root = catalog->getStructTreeRoot(); unsigned numChildren = root->getNumChildren(); for (unsigned i = 0; i < numChildren; i++) { StructElement *child = root->getChild(i); printChild(child); // recursive } Partial output from a version 1.4 PDF looks like: Document L (block) LI (block) LBody (block) P (block): Link (inline): Object 86 0 LI (block) LBody (block) P (block): Link (inline): Object 89 0 L (block) LI (block) LBody (block) P (block): Link (inline): Object 88 0 LI (block) LBody (block) P (block): Link (inline): Object 87 0 This finds the links which seem to have an object ref num (87 for example). How can I find out the URI or destination location in the document for this link? I have tried code similar to these 3 blocks: (I don't really understand the difference between the first two as the naming is confusing.) // 1. DestNameTreeDest int numDests = doc->getCatalog()->numDestNameTree(); for (int i = 0; i < numDests; i++) { LinkDest *dest = doc->getCatalog()->getDestNameTreeDest(i); // printf } // 2. DestsDest numDests = doc->getCatalog()->numDests(); for (int i = 0; i < numDests; i++) { LinkDest *dest = doc->getCatalog()->getDestsDest(i); // printf } // 3. Annot for (int i = firstPage; i <= lastPage; i++) { Page *p = doc->getPage(i); Annots *annots = p->getAnnots(); int numAnnots = annots->getNumAnnots(); for (int x = 0; x < numAnnots; x++) { Annot *a = annots->getAnnot(x); int type = a->getType(); if (type == Annot::typeLink) { AnnotLink *link = static_cast<AnnotLink *>(a); int kind = link->getAction()->getKind(); if (kind == 0) { // GoTo } else if (kind == 3) { // URI } } int id = a->getId(); const GooString *name = a->getName(); const GooString *contents = a->getContents(); // printf } } When I run the code on a version 1.4 PDF containing both internal links and web links the first 2 blocks don't seem to find anything. The last block finds the following: Annot 0 Type 2 (Link) Kind 0 (GoTo) Id: 86 Contents: Annot 1 Type 2 (Link) Kind 3 (URI) Id: 87 Contents: Annot 2 Type 2 (Link) Kind 3 (URI) Id: 88 Contents: Annot 3 Type 2 (Link) Kind 0 (GoTo) Id: 89 Contents: When I run the code on a different version 1.5 PDF containing both internal and web links I see the following: Page Destination Name 1 [ XYZ 346 209 null ] "EN-05-10531.indd:Application Number:1832" 1 [ XYZ 343 593 null ] "EN-05-10531.indd:Welcome to the Social Security Benefit Application:1830" ---vvv--- Begin Page 1 Annots ---vvv--- Printing 5 Annots.

Can anyone help point me in the right direction? Thanks. Shawn </div><div> </div></div></div></body></html>
