Description

This filter primitive composites input image layers on top of each other using the "over" operator with "input1" (corresponding to the first child merge node) on the bottom and the last specified input, "inputN" (corresponding to the last child merge node), on top.

Usage

feMerge(mergeNodes = NULL, ...)
addMergeNode(fe, mergeNode, after = NA)
feMergeNode(input = NA)

Arguments

mergeNodes	A list of fe.merge.node objects, produced by feMergeNode.
...	Further arguments to be passed onto fe.
fe	An fe.merge object, created by feMerge.
mergeNode	An fe.merge.node object, created by feMerge.
after	The position to add mergeNode to in the list of fe's children. When NA, appends to the end of the list of children.
input	Identifies an input for this filter primtive. See filterInputs.

Details

If you wish to add more merge nodes after an fe.merge object has been created, use addMergeNode to add merge nodes to the filter primitive.

For more information about the feMerge primitive, consult the reference to the SVG specification.

For feMerge, an fe.merge object.

For addMergeNode, an fe.merge object.
