for i := 13 downto 1 do
while (decimal >= arabics[i]) do begin
Decimal:= Decimal – Arabics[i];
scratch:= scratch + Romans[i];

Решение 1
Попробуйте:
var
Icon: TIcon;
Bitmap: TBitmap;
begin
Icon:= TIcon.Create;
Bitmap:= TBitmap.Create;
Icon.LoadFromFile('c:\picture.ico');
Bitmap.Width:= Icon.Width;
Bitmap.Height:= Icon.Height;
Bitmap.Canvas.Draw(0, 0, Icon);
Bitmap.SaveToFile('c:\picture.bmp');
Icon.Free;
Bitmap.Free;
end;
