During the SVG telcon this morning, we talked about what it would mean to allow additive animation of filter functions in the 'filter' property, and I said I would send a mail with some more details (this is my ACTION-3520). Remember that "additive animations" in SVG are those that layer on top of other animations for the same attribute/property. So if you had: <g> <animate attributeName="filter" dur="10s" values="grayscale(0.5) blur(0px); grayscale(1) blur(4px)"/> <animate attributeName="filter" dur="10s" values="opacity(1); opacity(0.5)" additive="sum"/> </g> what is the animated value of 'filter' at a given point during the animation? I think it makes sense for the "adding" operation to be "concatenate the lists". So the value at t=5s would be: grayscale(0.75) blur(2px) opacity(0.75)
