Re: Compositing math in SVG

Thanks for helping Rik.

Hmm, so you suggest I should do that for the result I get from this:

A*aa*(1-ba) + B*ba*(1-aa) + aa*ba*Blend(A, B)

In your example, the pre-multiplied color does not have green and blue
components and after the modification we have .5 for green and blue. This
does not make sense to me.
