feDisplacementMap element | SVGFEDisplacementMapElement object
Spatially displaces an image (in) using the pixel values of a second image (in2). The transformation uses the equation: P'(x,y) <- P( x + scale * ((XC(x,y) - .5), y + scale * (YC(x,y) - .5)) where P(x,y) is the source image, image1, and P'(x,y) is the destination. XC(x,y) and YC(x,y) are the component values of the designated by the x-channel-selector and y-channel-selector. For example, to use the red (R) component of image2 to control displacement in x and the green (G) component of image2 to control displacement in y, set x-channel-selector to "R" and y-channel-selector to "G". The displacement map defines the inverse of the mapping performed.
