Edit ada pada Standard ke form beri namenya dengan EditThreshold dan Text = 12. Seperti berikut ini.
Gambar 4.10 Edit Thresolding
13. Tambahkan program berikut ke UnitGlobalThressolding.
implementation {R .dfm}
uses ImageProses;
14. Doble klik button Global Thresolding lalu ketik program berikut
procedure TGlobalThreshold.btGlobalThresoldingClickSender: TObject; var thres:real;
begin Image2.Visible := True;
Image2.Picture.Graphic := Image1.Picture.Graphic; thres := StrToFloatDef EditThreshold.Text,5;
ImgGlobalThresholding Image2,thres,ProgressBar1; EditThreshold.Text := IntToStrRoundthres;
end;
15. Tambahkan button ke dalam form lalu captionnya diganti dengan Exit, namenya diberinama btExit.
Gambar 4.11 Button Exit
16. Doble klik button exit kemudin ketik program berikut.
procedure TFormGlobalThreshold.btExitClickSender: TObject; begin
FormGlobalThreshold.Close; end;
17. Simpan program dengan save all, kemudian jalankan progran dengan cara compile kemudian run. Hasilnya sebagai berikut.

18. Tutup program tekan button exit.
