[Swftools-common] blending mode 'value'?

[peter kostov]

Hello,

I have an idea for a design that I have to implement as a flash movie.
It consists basically of a stack of three images on top of each other.
The second layer is using a 'value' blending mode (in GIMP).
Unfortunately for me 'value' is not listed in the documentation of swfc 
under the 'blending modes' chapter. I know there are some cool features 
that are not documented yet, but it looks this is not the case, so is 
there any other way to achieve the same visual effect?

Greetings
Peter
