The blendLevel seems a better solution in this case, but getting back to the handler posted at the URL below, could it not be simplified even further:

on mouseUp
  put empty into aData
  put numToChar(128) into ch

  repeat for the number of chars in the alphaData of image 1
    put ch after aData
  end repeat

  set the alphaData of image 1 of aData
end mouseUp

You'll need to use images and manipulate their alphadata. See

Subject: Opacity Percentage?



Hi there,
I wanted to create a bunch of different color filters
and to be able to change the opacity by percentages.
I thought I'd use a basic rectangle and see if I could
change the opacity so that the object beneath it
shows through.
So far I haven't found a way to do this in Revolution.
Is there a way?
Thanks in advance.
Rick
