How to run it in Unigui?

install pdftk in your environment


and you can use this code:
 

procedure MergeAndEncryptPDFs(const AInputFiles: string; const AOutputFile: string; const AUserPassword: string);
var
  CommandLine: string;
  StartupInfo: TStartupInfo;
  ProcessInfo: TProcessInformation;
begin
  CommandLine := 'pdftk ' + AInputFiles + ' cat output ' + AOutputFile + ' user_pw ' + AUserPassword;

  FillChar(StartupInfo, SizeOf(StartupInfo), 0);
  StartupInfo.cb := SizeOf(StartupInfo);

  if CreateProcess(nil, PChar(CommandLine), nil, nil, False, 0, nil, nil, StartupInfo, ProcessInfo) then
  begin
    WaitForSingleObject(ProcessInfo.hProcess, INFINITE);
    CloseHandle(ProcessInfo.hProcess);
    CloseHandle(ProcessInfo.hThread);
	end
	else
		raise Exception.Create('not created');
end;

to call it:

 

procedure TMainForm.UniButton1Click(Sender: TObject);
var 
	OutPdf: string;
begin
	OutPdf :=  UniServerModule.NewCacheFile('pdf', fileName);
	MergeAndEncryptPDFs('example1.pdf,example2.pdf', OutPdf, '');
end;

you can modify the code to omit the password protection for your pdf.

hope it helps
