UserPermissions property

Component: TPdf · Unit: PDFium

Returns the user-password permission bits (a subset of Permissions).

Syntax

property UserPermissions;

Description

Returns the user-password permission bits (a subset of Permissions).

Equal to Permissions when the document is opened with the owner password.

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

if Pdf1.Active then
Pdf1.UserPermissions;
