Re: Compositing math in SVG

Ah, can't get it to work....

In the first case, what exactly is Cs and what is Cb?
Cb is the old background, but I am not clear with what Cs
is. From your example it seems it is B(Cb,Cs) but then
the formula:

c0 = ás x (1 - áb) x Cs + ás x áb x B(Cb, Cs) + (1 - ás) x áb x Cb

becomes:

c0 = á0 x (1 - áb) x B(Cb, Cs) + á0 x áb x B(Cb, B(Cb, Cs)) + (1 - á0) x áb x Cb

and that is confusing...
