Native PDFium FPDF_DOCUMENT handle for direct low-level access.

Syntax

property Document;

Description

Native PDFium FPDF_DOCUMENT handle for direct low-level access.

Use only when calling FPdfApi / FPdfEdit functions that PDFiumVCL does not wrap.

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

Remarks

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.

Example

if Pdf1.Active then
Pdf1.Document;
