Flash - Black and white image as mask

I'm unsure if Flash CS3 has this option but there's no reason for not having it.

In Flash 8 it's as follows:

1. Import your image to the stage (Ctrl+R).
2. Select your imported bitmap.
3. Go to the Modify menu -> Bitmap -> Trace bitmap.
4. Depending on how much detail you want, change around the options. If you want full detail use this:
    a) Color threshold: 1
    b) Minimum area: 1
    c) Curve fit: Very Smooth
    d) Corner threshold: Many Corners
5. It will probably take a bit if it's too detailed, once it's finished, it'll be turned into a Shape.
6. Select either the black or white bits of the image (just click on them) and delete them.
7. Voilá, you have a Shape that you can now use as a mask.

Hope this helps, there shouldn't really be much trouble porting this to CS3, it must be almost identical.

Good Luck.

Thanks for that idea!  Although the source image has gradients and blurs in it (key part of the mask effect).

Thoughts?
