`pdfAddObjRefToStruct`

Bind an annotation to the currently-open structure element

BOOL32 __stdcall pdfAddObjRefToStruct(PPDF IPDF, uint32_t Annot);

Delphi

function pdfAddObjRefToStruct(const IPDF: PPDF; Annot: Cardinal): LongBool; stdcall;

Purpose. Bind an annotation to the currently-open structure element as an /OBJR (object reference) child — the tagged-PDF mechanism for associating a non-text marked-content object (like an annotation) with its place in the accessibility structure tree.

Description. Requires a structure tag to already be open (via pdfOpenTag, V03) — operates on "the open struct element," not an explicit tag handle parameter.

Parameters.

Parameter	Description
`IPDF`	Document handle.
`Annot`	The annotation handle to bind as an `/OBJR` child of the currently-open tag.

Return value. True on success (a tag was open and the binding was added).
