gradientTransform - SVG: Scalable Vector Graphics 编辑

The gradientTransform attribute contains the definition of an optional additional transformation from the gradient coordinate system onto the target coordinate system (i.e., userSpaceOnUse or objectBoundingBox). This allows for things such as skewing the gradient. This additional transformation matrix is post-multiplied to (i.e., inserted to the right of) any previously defined transformations, including the implicit transformation necessary to convert from object bounding box units to user space.

Two elements are using this attribute: <linearGradient> and <radialGradient>

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

<svg viewBox="0 0 420 200" xmlns="http://www.w3.org/2000/svg">
  <radialGradient id="gradient1" gradientUnits="userSpaceOnUse"
      cx="100" cy="100" r="100" fx="100" fy="100">
    <stop offset="0%" stop-color="darkblue" />
    <stop offset="50%" stop-color="skyblue" />
    <stop offset="100%" stop-color="darkblue" />
  </radialGradient>
  <radialGradient id="gradient2" gradientUnits="userSpaceOnUse"
      cx="100" cy="100" r="100" fx="100" fy="100"
      gradientTransform="skewX(20) translate(-35, 0)">
    <stop offset="0%" stop-color="darkblue" />
    <stop offset="50%" stop-color="skyblue" />
    <stop offset="100%" stop-color="darkblue" />
  </radialGradient>

  <rect x="0" y="0" width="200" height="200" fill="url(#gradient1)" />
  <rect x="0" y="0" width="200" height="200" fill="url(#gradient2)" style="transform: translateX(220px);" />
</svg>
