pdfGetInDocInfo

Purpose — Read a document-info field from the currently open import source (not the output document).

Description — Reads directly from the import file's parsed /Info dictionary — this is a live read of someone else's PDF, so unlike the output side, diCompany/diPDFX_Ver(7)/diCustom(8)/diPDFX_Conf(9) that lack a standard key name (Company and Custom have none in the reference /Info schema either) simply return nothing; there is no equivalent "silently dropped at write time" issue here since this path never writes.

Declarations

int32_t __stdcall pdfGetInDocInfo(PPDF IPDF, TDocumentInfo DInfo, const wchar_t* Value);

function pdfGetInDocInfo(const IPDF: PPDF; DInfo: TDocumentInfo; var Value: PWideChar): Integer; stdcall; external 'LumasPdf.dll';

Parameters

Return value — String length, or 0 if unset, no import source is open, or DInfo has no standard key.

Memory & buffers — Value points at an engine-owned buffer valid until the next call.
