The yChannelSelector attribute indicates which color channel from in2 to use to displace the pixels in in along the y-axis.

You can use this attribute with the following SVG elements:

<feDisplacementMap>

Example

html, body, svg {
  height: 100%;
}

<svg viewBox="0 0 440 160" xmlns="http://www.w3.org/2000/svg">
  <filter id="displacementFilter">
    <feImage xlink:href="mdn.svg"
        x="0" y="0" width="100%" height="100%" result="abc"/>
    <feDisplacementMap in2="abc" in="SourceGraphic"
        scale="30" yChannelSelector="R"/>
  </filter>
  <filter id="displacementFilter2">
    <feImage xlink:href="mdn.svg"
        x="0" y="0" width="100%" height="100%" result="abc"/>
    <feDisplacementMap in2="abc" in="SourceGraphic"
        scale="30" yChannelSelector="B"/>
  </filter>

  <text x="10" y="60" font-size="50"
      filter="url(#displacementFilter)">Some displaced text</text>
  <text x="10" y="120" font-size="50"
      filter="url(#displacementFilter2)">Some displaced text</text>
</svg>

R: This keyword specifies that the red color channel of the input image defined in in2 will be used to displace the pixels of the input image defined in in along the y-axis.
G: This keyword specifies that the green color channel of the input image defined in in2 will be used to displace the pixels of the input image defined in in along the y-axis.
B: This keyword specifies that the blue color channel of the input image defined in in2 will be used to displace the pixels of the input image defined in in along the y-axis.
A: This keyword specifies that the alpha channel of the input image defined in in2 will be used to displace the pixels of the input image defined in in along the y-axis.
