Re: Compositing math in SVG

Rik,

1. "Where is the alpha coming from? Is it already in the image that you're
applying blending to?"

I created the images A and B in Photoshop, A has opacity
75% and B has 100%, so the alpha is coming
from the images yes.

2. "If so, you need to alpha blend with the background first and then
blend."

You mean alpha blend the top image A with bottom/background image B?
And then blend with...? I am confused, so I am not supposed to use that
formula?

Thanks
