Usage notes
- Enumerate annotations with
THotPDF.GetLoadedAnnotationCountand fetch each one withTHotPDF.GetLoadedAnnotationInfo; afalseresult leaves the record set to zero - Use
ObjectNumberwithTHotPDF.GetLoadedAnnotationDictwhen you need entries that go beyond the summary fields - The FDF interchange exporter consumes this record when serialising annotations, so its fields define exactly what round-trips through FDF
