SaveAsPadesDss - TPdf

Component: TPdf · Unit: PDFium

Tallentaa aktiivisen PDF:n tiedostoon upottaen PAdES Document Security Store (DSS) -validointivarmenteet

Syntax

function SaveAsPadesDss(const FileName: string; const Options: TPadesDssOptions): Boolean; overload;

Description

Tallentaa nykyisen asiakirjan tavut tiedostoon samalla kun X.509-validointimateriaaleja lisätään asiakirjan globaaliin /DSS-sanakirjaan

Edellyttää Active-arvon True; palauttaa False, jos tallennus epäonnistuu

Parameters

FileName	Absolute or relative path to the destination file
Options	DSS configuration structure containing arrays of X.509 DER-encoded blobs and extension settings

Remarks

This represents stage 4 of validation-material embedding, necessary to transition a B-T signature level to a long-term B-LT or B-LTA level
The original document is saved as a new file via an incremental update containing the added /DSS markers
The incremental update preserves the source xref table or xref-stream representation and uses 64-bit offsets in 64-bit builds

Example

var
  DssOpts: TPadesDssOptions;
begin
  if not Pdf1.Active then Exit;
  DssOpts := TPadesDssOptions.Default;
  // populate DssOpts.Certs with DER validation certificates
  Pdf1.SaveAsPadesDss('signed-blt.pdf', DssOpts);
end;
