How to apply alpah to BitmapFill when drawing image to stage??

Question

I'm just starting with AS3 from AS2, but understand basics of code, so bear with me.
I got this code from www.kirupa.com; it writes an image to stage as a way of tile it.
holidaytile is an instance of a Gif Image.
But I want to change the Alpha so that my top layer shows through it, and I can't seem
to figure out how to do that.
import flash.display.BitmapData;
var tile:BitmapData = BitmapData.loadBitmap("holidaytile");
this.beginBitmapFill(tile);
this.lineTo(Stage.width,0);
this.lineTo(Stage.width, Stage.height);
this.lineTo(0, Stage.height);
this.lineTo(0, 0);
this.endFill();
Thanks if you can help, I'll keep looking

Well I created the Class using the import.flash.display.BitmapData
then created a var: tile to hold the instance with var tile:BitmapData = BitmapData.loadBitmap("holidaytile");
Then this.beginBitmapFill(tile);  I believe loads the Bitmap with the instance
And the following code writes it all to stage
this.lineTo(Stage.width,0);
this.lineTo(Stage.width, Stage.height);
this.lineTo(0, Stage.height);
this.lineTo(0, 0);
this.endFill();
But where would I put the alpha control?? I've tried in a few places e.g
BitmapFill.alpah = 0.5; But there is no change.
