`pdfGetInDocInfoEx`

Enumerate the import source's document-info entries by index,

Category	Document metadata (import)

Purpose — Enumerate the import source's document-info entries by index, mapped back to TDocumentInfo where recognized.

Description — Walks the same fixed 12-slot key table as pdfGetInDocInfo (Author, Creator, Keywords, Producer, Subject, Title, *(no diCompany key)*, GTS_PDFXVersion, *(no diCustom key)*, GTS_PDFXConformance, CreationDate, ModDate) — Index here indexes into this fixed table by position, not into the raw /Info dictionary's actual key set (contrast with pdfGetInDocInfoCount, which counts the raw dictionary). On failure, Ord_ defaults to 8 (diCustom) as a sentinel.

Declarations

BOOL32 __stdcall pdfGetInDocInfoEx(PPDF IPDF, uint32_t Index, TDocumentInfo* DInfo, const char* Key, const char* Value, BOOL32* Unicode);

Delphi

function pdfGetInDocInfoEx(const IPDF: PPDF; Index: Cardinal; var DInfo: TDocumentInfo; var Key, Value: PAnsiChar; var Unicode: LongBool): LongBool; stdcall; external 'LumasPdf.dll';

Parameters

Parameter	Type	Description
`IPDF`	`PPDF`	Instance handle with an open import source.
`Index`	`Cardinal`	Position in the fixed 12-entry key table (not the raw dictionary's key order).
`DInfo`	`TDocumentInfo*`	Receives the ordinal; `8` (`diCustom`) on failure.
`Key`	`PAnsiChar*`	Always `NULL` in this build.
`Value`	`PAnsiChar*`	Receives the value (empty if this slot has no data in the source file).
`Unicode`	`BOOL32*`	Always `FALSE`.

Return value — TRUE if Index is 0..11 and the import source is open; FALSE otherwise (this call does not fail just because a given slot's value is empty — check Value for that).
