Loads the PDFium runtime DLL into the process. Called implicitly by Active := True.

Loads the PDFium runtime DLL into the process. Called implicitly by Active := True.

Pass a custom path to use a non-default DLL location; pass an empty string for the default search.

Wraps the corresponding PDFium API and exposes it as a TPdf instance member so consumers do not have to manage FPDF_DOCUMENT handles directly.

• Always check Pdf1.Active before calling page-scoped operations; methods that require an open document raise EPdfError otherwise.
• Document-edit methods (AddPage / DeletePage / UpdatePage / CreateAnnotation) leave the in-memory document dirty — remember to call SaveToFile to persist.
• Class methods (LoadLibrary / UnloadLibrary / GetRecommendedV8Flags) can be called without a TPdf instance.
