Component: TPdf · Unit: PDFium
Returns the document XMP metadata packet as a wide string.
Syntax
property MetaText;
Description
Returns the document XMP metadata packet as a wide string.
Empty when the document has no /Metadata stream.
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.MetaText;
