The <feMerge> SVG element allows filter effects to be applied concurrently instead of sequentially. This is achieved by other filters storing their output via the result attribute and then accessing it in a <feMergeNode> child.
Usage context
| Categories | Filter primitive element |
|---|---|
| Permitted content | Any number of the following elements, in any order:<feMergeNode> |
