menentukan intensitas rgb Menggunakan Delphi 7 Fisika Komputasi

Pembahasan kali ini yaitu tentang cara menentukan intensitas RGB dengan delphi desain yang akan kita buat, , , , menampilkan foto dan dengan menggerakkan scrole kita dapat secara langsung melihat intensitas RGB nya. Cukupp simple kan. . . . Nah berikut adalah tampilan awalnya pada delphi;

series 1 menunjukkan red



series 2 menunjukkan green

series 3 menunjukkan blue

Berikut adalah syntaknya >>>>>

unit Unit1;
interface uses Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms, Dialogs, StdCtrls, TeEngine, Series, ExtCtrls, TeeProcs, Chart, jpeg;
type TForm1 = class(TForm)
Image1: TImage;
OpenDialog1: TOpenDialog;
Chart1: TChart;
Series1: TLineSeries;
Series2: TLineSeries;
Series3: TLineSeries;
Label1: TLabel;
Label2: TLabel;
Label3: TLabel;

ScrollBar1: TScrollBar;
Button1: TButton;
procedure Button1Click(Sender: TObject);
procedure ScrollBar1Change(Sender: TObject);
procedure Button2Click(Sender: TObject);
procedure FormCreate(Sender: TObject);
procedure Image1Click(Sender: TObject);
procedure Image1MouseMove(Sender: TObject;Shift: TShiftState; X, Y: Integer);
procedure FormClose(Sender: TObject; var Action: TCloseAction);
private { Private declarations } public { Public declarations } end;

var
Form1: TForm1;
gambar2 :Tbitmap;
implementation
{$R *.dfm}
procedure TForm1.Button1Click(Sender: TObject);
var red,green,blue:byte;
a,b,lebar:Integer;
warna:TColor;
open:string;
begin OpenDialog1.Execute;
open:=OpenDialog1.FileName;
Image1.Picture.LoadFromFile(open);
scrollbar1.Enabled := True;
gambar2.Assign(Image1.Picture);
ScrollBar1.Max:=Image1.Picture.Height;
end;


procedure TForm1.FormCreate(Sender: TObject);
begin gambar2:=TBitmap.Create;
// ScrollBar1.Max:=Image1.Picture.Height;
end;

procedure TForm1.ScrollBar1Change(Sender: TObject);
var red,green,blue:byte;
a,b,lebar:Integer;
warna:TColor;
garis:TBitmap;
begin Series1.Clear;
Series2.Clear;
Series3.Clear;
b:=ScrollBar1.Position;
lebar:=Image1.Picture.Bitmap.Width;
garis:=TBitmap.Create;
garis.Assign(gambar2);
garis.Canvas.MoveTo(0,b);
garis.Canvas.LineTo(lebar,b);
for a:=0 to lebar -1 do
begin warna:=Image1.Picture.Bitmap.Canvas.Pixels[a,b];
red:=GetRValue(warna);
green:=GetGValue(warna);
blue:=GetBValue(warna);
Series1.AddXY(a,red);
Series2.AddXY(a,green);
Series3.AddXY(a,blue);
end;

Image1.Picture.Assign(garis);
garis.Free;
end;

procedure TForm1.Button2Click(Sender: TObject);
var open:string;
begin OpenDialog1.Execute;
open:=OpenDialog1.FileName;
Image1.Picture.LoadFromFile(open);
end;

procedure TForm1.Image1MouseMove(Sender: TObject;Shift: TShiftState; X,Y: Integer); var warna:TColor;
begin warna:=Image1.Picture.Bitmap.Canvas.Pixels[X,Y];
Label1.Caption:= inttostr(GetRValue(warna));
Label2.Caption:= IntToStr(GetGValue(warna));
Label3.Caption:= IntToStr(GetBValue(warna));
end;
procedure TForm1.Image1Click(Sender: TObject);
begin gambar2:=TBitmap.Create;
ScrollBar1.Max:=Image1.Picture.Height;
end;
procedure TForm1.FormClose(Sender: TObject; var Action: TCloseAction);
begin gambar2.Free;
end;
end.

setelah itu, coba kita jalankan dan hasilnya seperti berikut >>>>> pada saat kita run, ada perintah untuk memasukkan foto, masukkan foto anda dalam tipe Bitmapp,

Selamat Mencoba ^^
