The exponent attribute defines the exponent of the gamma function.

You can use this attribute with the following SVG elements:

Example

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

<svg viewBox="0 0 420 200" xmlns="http://www.w3.org/2000/svg">
  <defs>
    <linearGradient id="gradient" gradientUnits="userSpaceOnUse"
        x1="0" y1="0" x2="200" y2="0">
      <stop offset="0" stop-color="#ff0000" />
      <stop offset="0.5" stop-color="#00ff00" />
      <stop offset="1" stop-color="#0000ff" />
    </linearGradient>
  </defs>

  <filter id="componentTransfer1" x="0" y="0" width="100%" height="100%">
    <feComponentTransfer>
      <feFuncR type="gamma" exponent="1"/>
      <feFuncG type="gamma" exponent="1"/>
      <feFuncB type="gamma" exponent="1"/>
    </feComponentTransfer>
  </filter>
  <filter id="componentTransfer2" x="0" y="0" width="100%" height="100%">
    <feComponentTransfer>
      <feFuncR type="gamma" exponent="5"/>
      <feFuncG type="gamma" exponent="5"/>
      <feFuncB type="gamma" exponent="5"/>
    </feComponentTransfer>
  </filter>

  <rect x="0" y="0" width="200" height="200" fill="url(#gradient)"
      style="filter: url(#componentTransfer1);" />
  <rect x="0" y="0" width="200" height="200" fill="url(#gradient)"
      style="filter: url(#componentTransfer2); transform: translateX(220px);" />
</svg>

Usage notes

Value	`<number>`
Default value	`1`
Animatable	Yes

<number>: If the type attribute of the component element is set to gamma, this value specifies the exponent of the gamma function
