Undeclared Picture1 ?

[taktaky]

Hallo

warum muss ich Picture1 deklarieren ?

Delphi-Quellcode:

procedure TForm1.BitBtn2Click(Sender: TObject);
begin
  if OpenPictureDialog1.Execute then
  begin
Image1.Picture.LoadFromFile('vorschau.bmp');
Image1.Height:=Picture1.Height * Image1.Height / Picture1.Width; // undeclared Picture1 !
Image1.Stretch  := true;
 end;
end;

Picture1 ist das Bild in Image1. warum Undeclaed ?
