Class StructureElementIter

Documents may have an associated structure tree &mdashmostly, Tagged-PDF compliant documents— which can be used to obtain information about the document structure and its contents. Each node in the tree contains a #PopplerStructureElement.

Here is a simple example that walks the whole tree:

static void walk_structure (PopplerStructureElementIter iter) { do { / Get the element and do something with it */ PopplerStructureElementIter *child = poppler_structure_element_iter_get_child (iter); if (child) walk_structure (child); poppler_structure_element_iter_free (child); } while (poppler_structure_element_iter_next (iter)); } ... { iter = poppler_structure_element_iter_new (document); walk_structure (iter); poppler_structure_element_iter_free (iter); }
