[comp.sys.mac.hypercard] Lighten menu

Some one here wants to be able to display pictures on the screen and
then degrade them a certain amount. We are looking at using the
Lighten menu. The problem is we don't know exactly what its doing.
He will want to degrade the picture 5% then 10%, etc. The manuals
we have just say it switchs some pixels. We need more info than
that. If you know or know where we can look please email to one
of the addresses below.       
 
Thanks
