additive - SVG: Scalable Vector Graphics 编辑

The additive attribute controls whether or not an animation is additive.

It is frequently useful to define animation as an offset or delta to an attribute's value, rather than as absolute values.

Four elements are using this attribute: <animate>, <animateColor>, <animateMotion>, and <animateTransform>

Usage notes

sum

Specifies that the animation will add to the underlying value of the attribute and other lower priority animations.

replace

Specifies that the animation will override the underlying value of the attribute and other lower priority animations. This is the default, however the behavior is also affected by the animation value attributes by and to, as described in SMIL Animation: How from, to and by attributes affect additive behavior.
