Details¶

class Poppler.StructureElementIter¶

Since 24.10 this type supports g_autoptr

classmethod new(poppler_document)¶

Parameters:: poppler_document (Poppler.Document) – a Poppler.Document.
Returns:: a new Poppler.StructureElementIter, or None if document doesn’t have structure tree.
Return type:: Poppler.StructureElementIter

Returns the root Poppler.StructureElementIter for document, or None. The returned value must be freed with Poppler.StructureElementIter.free().

Documents may have an associated structure tree —mostly, 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 Poppler.StructureElement.

Here is a simple example that walks the whole tree:

<informalexample><programlisting> static void walk_structure (Poppler.StructureElementIter *iter) { do { /<!– –>* Get the element and do something with it *<!– –>/ Poppler.StructureElementIter *child = Poppler.StructureElementIter.get_child (iter); if (child) walk_structure (child); Poppler.StructureElementIter.free (child); } while (Poppler.StructureElementIter.next (iter)); } … { iter = Poppler.StructureElementIter.new (document); walk_structure (iter); Poppler.StructureElementIter.free (iter); } </programlisting></informalexample>

copy()¶

Returns:: a new Poppler.StructureElementIter
Return type:: Poppler.StructureElementIter

Creates a new Poppler.StructureElementIter as a copy of self. The returned value must be freed with Poppler.StructureElementIter.free().

New in version 0.26.

free()¶: Frees self.

New in version 0.26.

get_child()¶

Returns:: a new Poppler.StructureElementIter
Return type:: Poppler.StructureElementIter

Returns a new iterator to the children elements of the Poppler.StructureElement associated with iter. The returned value must be freed with Poppler.StructureElementIter.free().

New in version 0.26.

get_element()¶

Returns:: a new Poppler.StructureElementIter
Return type:: Poppler.StructureElement

Returns the Poppler.StructureElementIter associated with self.

New in version 0.26.

next()¶

Returns:: True, if self was set to the next structure element
Return type:: bool

Sets self to point to the next structure element at the current level of the tree, if valid. See Poppler.StructureElementIter.new() for more information.
