a glyph is already an ordinary bitmap

to convert an icon to a bitmap,
just could use the stretchdraw mthod of a bitmap.canvas

I know it's a bitmap, but when i try input some *.bmp, it show very bad, i want to know what color of image will be transparent and save bitmap on 8 bit, 24 bit... is best.

Hi z27,
Use this code and let me if I've solved your problem ;)

procedure bmp2ico(Image: TImage; FileName: TFilename);
var
  Bmp: TBitmap;
  Icon: TIcon;
  ImageList: TImageList;
begin
  Bmp  := TBitmap.Create;
  Icon := TIcon.Create;
  try
    Bmp.Assign(Image.Picture);
    ImageList := TImageList.CreateSize(Bmp.Width, Bmp.Height);
    try
      ImageList.AddMasked(Bmp, Bmp.TransparentColor);
      ImageList.GetIcon(0, Icon);
      Icon.SaveToFile(FileName);
    finally
      ImageList.Free;
    end;
  finally
    Bmp.Free;
    Icon.Free;
  end;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
  bmp2ico(Image1, 'c:\test.ico');
end;

Bye till...
