GetAnnotReplyTo

Annotations and hotspot links

Description

Returns the 1-based annotation index referenced by the selected annotation's /IRT entry

Use it to resolve the parent annotation for threaded replies and review-state annotations without reading generic annotation property tags directly

Syntax

Delphi

Function TPDFlib.GetAnnotReplyTo(Index: Integer): Integer;

Parameters

Index is the 1-based index of the annotation on the selected page

Return Values

Returns the 1-based target annotation index, or 0 when the annotation has no /IRT entry or the referenced annotation is not on the selected page

Remarks

Pair with GetAnnotReplyType to inspect the /RT relationship name. AddAnnotationReply writes normal replies with /RT /R
