SetObjectJSON

Object model, document editing

Description

Validates one typed JSON value and replaces the selected existing indirect object while preserving its object and generation numbers. Dictionaries, arrays, streams, scalar values, and references retain their PDF types. Parsing and cloning complete before the object is changed, so malformed input leaves the original object intact

Syntax

Delphi

Function TPDFlib.SetObjectJSON(ObjectNumber: Integer; Const JSON: AnsiString; Options: Integer): Integer;

ActiveX

Function PDFlib::SetObjectJSON(ObjectNumber As Long, JSON As String, Options As Long) As Long

DLL

int DLSetObjectJSON(int InstanceID, int ObjectNumber, const char* JSON, int Options);

Parameters

ObjectNumber	Existing indirect object number to replace
JSON	Typed value returned by `GetObjectJSON` or extracted from an object graph
Options	Must be 0

Return values

1	The object was replaced
0	The object or JSON is invalid; `LastErrorCode` is 105
