הערות

Each finding is one Level,Code,Object,Message line with level error, warning or info; the last line is a summary,... with error and warning counts, the number of objects and streams checked and the page resolution ratio. Reported conditions include objects that fail to parse (object-decode), plain Flate streams that are truncated or corrupt (stream-decode, verified strictly against the zlib end marker), a missing trailer or unresolvable document catalog, unsupported encryption handlers, unresolvable pages and documents whose cross-reference data was rebuilt from a byte scan (repaired).

Use it as an inexpensive pre-flight gate before archiving or batch processing; CheckFileCompliance covers standards conformance while this call covers structural integrity.

ListID:= PDF.CheckDocumentStructure;
Last:= PDF.GetStringListItem(ListID, PDF.GetStringListCount(ListID));
if Pos('summary,0 errors', Last)<> 1 then
  ShowMessage('structural problems found');
PDF.ReleaseStringList(ListID);
