convertOneStopGradients

Converts the <linearGradient> and <radialGradient> nodes that are effectively a solid color to the color.

These nodes contain <stop> elements, which represent various colors to transition between. However, if a gradient only contains a single <stop>, then it's effecitively a solid fill.

Definitions of the gradients are removed, and the parent <defs> node is removed if it has no children after optimization. The xlink:href namespace is also removed if there are no remaining elements using this attribute.

Usage

svgo.config.js
module.exports = {
  plugins: [
    "convertOneStopGradients"
  ]
}
