Description Usage Arguments Details Value Author(s) References See Also

This filter primitive uses the pixels values from the image from input2 to spatially displace the image from input1.

feDisplacementMap(input1 = NA, input2 = NA,
                  scale = 0,
                  xChannelSelector = c("A", "R", "G", "B"),
                  yChannelSelector = c("A", "R", "G", "B"),
                  ...)

`input1`	Identifies an input for this filter primtive. See `filterInputs`.
`input2`	Identfies a second input for this filter primitive. See `filterInputs`.
`scale`	Displacement scale factor. The amount is expressed in the coordinate system established by attribute `primitiveUnits` on the parent filter container. When the value of `scale` is 0, this operation has no effect on the source image.
`xChannelSelector`	Indicates which channel from `input2` to use to displace the pixels in `input` along the x-axis.
`yChannelSelector`	Indicates which channel from `input2` to use to displace the pixels in `input` along the y-axis.
`...`	Further arguments to be passed onto `fe`.
