Its in flash, and a bit incomplete, but you may find it helpful.
EDIT: In case you were wondering, tileMapBitmap was defined as a class. It is a derivitive of the BitmapData class, and is created when a image is imported into flash. This LOC [LOC 3] basically made an instance of it.
Then I copied sections of it into another BitmapData object, compiled that into a Bitmap object and then added it to the display list.
