function pdfGetTemplHandle(const IPDF: PPDF): Integer; stdcall;

Purpose. Total template count; the most-recently-created template's handle; a specific template's dimensions.

Description. pdfGetTemplHandle returns a specific, deliberately convention-matched negative error sentinel (-67109019) when no template exists yet, rather than a generic 0/-1 — an explicit source comment confirms this mirrors "dyna['s] no-template error code" exactly, for callers that check against that specific magic number.

Parameters.

Return value. pdfGetTemplCount: total count; 0 if IPDF invalid. pdfGetTemplHandle: the most-recent template's handle, or the convention-matched sentinel -67109019 if none exists. pdfGetTemplHeight/ Width: the dimension; 0.0 if TmplHandle doesn't resolve.
