<feDisplacementMap>

The <feDisplacementMap> SVG filter primitive uses the pixel values from the image from in2 to spatially displace the image from in.

The formula for the transformation looks like this:

P'(x,y) ← P(x + scale * (XC(x,y) - 0.5), y + scale * (YC(x,y) - 0.5))

where P(x,y) is the input image, in, and P'(x,y) is the destination. XC(x,y) and YC(x,y) are the component values of the channel designated by xChannelSelector and yChannelSelector.

Like other filter primitives, it handles color components in the linearRGB color space by default. You can use color-interpolation-filters to use sRGB instead.
