TImageList component used to draw a transparent bitmap.

var
bm : TBitmap;
il : TImageList;
begin
bm := TBitmap.Create;
bm.LoadFromFile('C:\DownLoad\TEST.BMP');
il := TImageList.CreateSize(bm.Width,
bm.Height);
il.DrawingStyle := dsTransparent;
il.Masked := true;
il.AddMasked(bm, clRed);
il.Draw(Form1.Canvas, 0, 0, 0);
bm.Free;
il.Free;
end;
