PDF Merge

Delphi-Quellcode:

procedure TForm1.Button2Click(Sender: TObject);
var
  argv: Array of PAnsiChar;
  instance: Pointer;
  x: Integer;
begin
  // new(instance);  //how many bytes, this really doesn't make sense with a untyped pointer!
  // setlength(argv, 4);
  // argv[0] := PANsiChar('ps2pdf');
  // argv[1] := PAnsiChar('-dNOPAUSE');
  // argv[2] := PAnsiChar('-dBATCH');
  // argv[3] := PAnsiChar('-dSAFER');
  // gsapi_init_with_args(instance, Length(argv), PPAnsiChar(argv));
  // gsapi_exit(instance);
  gsapi_new_instance(instance, instance);
  // ShowMessage(inttostr(x));
  // new(instance);  //how many bytes, this really doesn't make sense with a untyped pointer!
  setlength(argv, 5);
  argv[0] := PAnsiChar('');
  argv[1] := PAnsiChar('-dNOPAUSE');
  argv[2] := PAnsiChar('-sDEVICE=pdfwrite');
  argv[3] := PAnsiChar('-sOUTPUTFILE= ' + JvFilenameEdit3.Text);
  argv[4] := PAnsiChar(' -dBATCH ' + JvFilenameEdit1.Text + ' ' +
    JvFilenameEdit2.Text);
  gsapi_init_with_args(instance, Length(argv), PPAnsiChar(argv));
  gsapi_exit(instance);
  showmessage('fertig!');

end;

Danke HolgerX!
Das funktioniert aber nicht, kommt nicht mal ne Fehlermeldung!
