UnloadLibrary method

Component: TPdf · Unit: PDFium

Otpušta PDFium runtime DLL i oslobađa sav globalni stanje

Syntax

procedure UnloadLibrary;

Description

Unloads the PDFium runtime DLL and releases all global state.

Optional — useful when the host process keeps the DLL pinned but wants the memory back. Cannot be called while TPdf instances are still active.

Omotava odgovarajući PDFium API i izlaže ga kao član instance TPdf tako da korisnici ne moraju izravno upravljati FPDF_DOCUMENT ručkama.

Remarks

Uvijek provjerite Pdf1.Active prije pozivanja operacija na razini stranice; metode koje zahtijevaju otvoreni dokument inače podižu EPdfError.
Metode uređivanja dokumenta (AddPage / DeletePage / UpdatePage / CreateAnnotation) ostavljaju dokument u memoriji prljavim — ne zaboravite pozvati SaveToFile za trajno spremanje.
Metode klase (LoadLibrary / UnloadLibrary / GetRecommendedV8Flags) mogu se pozvati bez instance TPdf.

Example

begin
TPdf.UnloadLibrary;
end;
