Help! Bitmap transparency problems!

[untitled]

Stumped... i'm loading an external png file into a MovieClip then drawing it to a BitmapData object, problem is the BitmapData object isn't keeping the transparency on the original png. Am i out of luck here?

You need to ensure that the BitmapData object you create, supports transparency:

import flash.display.BitmapData
var b=new BitmapData(mc._width,mc._height,true,0x00000000)
b.draw(mc)
