Bitmap alpha problem

i am drawing a brain fart this morning.
how do i do this agian or does any one have a quick tutorial.

In flash 8 you can use the bitmap data class to create soft edges on your
masks (by storeing the mask as a bitmap and allowing the use of its alpha
channel)

Http://www.gotoandLearn.com. You can view the one for “Creating alhpa bitmaps” which I believe is exactly what you need. Or youc an see the one on Bitmap data class.

great
