pdfGetDocInfoCount

Purpose — Number of document-info fields currently set.

Declarations

int32_t __stdcall pdfGetDocInfoCount(PPDF IPDF);

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

Return value — Count of in-memory entries (0 if the handle is invalid). Seeded to 1 immediately after document creation — see Remarks.

Remarks — A fresh document always starts with one entry already present: diProducer is seeded to "Lumas PDF Engine" at creation time (matching the XMP pdf:Producer value this engine writes for PDF/A conformance), so pdfGetDocInfoCount returns 1, not 0, before you set anything.
