Animation Addition Attributes¶
'replace | sum'
Controls whether or not the animation is additive.
||Specifies that the animation will add to the underlying value of the attribute and other lower priority animations.|
||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.|
'none | sum'
Controls whether or not the animation is cumulative.
||Specifies that each repeat iteration after the first builds upon the last value of the previous iteration.|
||Specifies that repeat iterations are not cumulative. This is the default.|
This attribute is ignored if the target attribute value does not support addition, or if the animation element does not repeat.
Cumulative animation is not defined for “to animation”.
This attribute will be ignored if the animation function is specified with only the to attribute.
