pdfGetInDocInfoCount

Purpose — Number of entries in the import source's /Info dictionary.

Declarations

int32_t __stdcall pdfGetInDocInfoCount(PPDF IPDF);

function pdfGetInDocInfoCount(const IPDF: PPDF): Integer; stdcall; external 'LumasPdf.dll';

Return value — Entry count of the import file's raw /Info dictionary (counts *every* key present in the source PDF, including nonstandard ones — unlike pdfGetInDocInfoEx, which can only surface the ones with a recognized TDocumentInfo mapping). Returns the sentinel NO_IMPORT_ERR (-1073742011) — not 0 — when no import source is open; check pdfHaveOpenDoc-style import-open state, or expect a large negative value rather than zero, if you call this before opening an import file.
