Is there an algorithm or routine to convert 32x32 bit Bitmaps to ICO's?

--------------------------------------------------------------------------------

unit main;

interface

  Windows, Messages, SysUtils, Classes, Graphics, Controls,

  Forms,Dialogs,ExtCtrls, StdCtrls;

  TForm1 = class(TForm)

    Image1: TImage;

    Image2: TImage;

    procedure FormCreate(Sender: TObject);

var winDC, srcdc, destdc : HDC;

    oldBitmap : HBitmap;

    iinfo : TICONINFO;

begin

    GetIconInfo(Image1.Picture.Icon.Handle, iinfo);

    WinDC := getDC(handle);

    srcDC := CreateCompatibleDC(WinDC);

    oldBitmap := SelectObject(srcDC, iinfo.hbmMask);

    BitBlt(destdc, 0, 0, Image1.picture.icon.width,

            Image1.picture.icon.height,

           srcdc, 0, 0, SRCPAINT);

    Image2.picture.bitmap.handle := SelectObject(destDC, oldBitmap);

    DeleteDC(destDC);

    DeleteDC(srcDC);

    DeleteDC(WinDC);

 image2.Picture.Bitmap.savetofile(ExtractFilePath(Application.ExeName)

          + 'myfile.bmp');

end;

procedure TForm1.FormCreate(Sender: TObject);
