[M4IF Technotes] [M4IF Infolist] MPEG-4 Question about alpha values

[axel.binder philips.com]

Hi,
I found several places where alpha values are calculated
for gray level shapes and during BIFS lighting. However,
I couldn't find any place where these values (from the frame
buffer, composed scene) are used again. Did I miss something
or are the calculations of the destination alpha values
obsolete?
Thanks in advance
Axel
