pdfGetAnnotCount

int32_t __stdcall pdfGetAnnotCount(PPDF IPDF);

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

Purpose. Return the total number of annotations across every page in the document.

Description. Sums CreatedAnnots.Count over every page — not FAnnotByHandle.Count. These two counts can diverge: pdfDeleteAnnotationFromPage (below) removes an annotation from a page's list (decrementing this count) without removing its entry from FAnnotByHandle, so a handle can remain resolvable via pdfGetAnnot for an annotation this count no longer includes.

Parameters.

Return value. The total per-page annotation count summed across the document; 0 if IPDF is invalid.
