SVGPatternElement: patternContentUnits property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2020.

The patternContentUnits read-only property of the SVGPatternElement interface reflects the patternContentUnits attribute of the given <pattern> element. It specifies the coordinate system for the pattern content and takes one of the constants defined in SVGUnitTypes.

Value

Example

Given the following SVG:

html
<svg viewBox="0 0 200 200" xmlns="http://www.w3.org/2000/svg">
  <defs>
    <pattern
      id="pattern1"
      width="10"
      height="10"
      patternContentUnits="userSpaceOnUse">
      <circle cx="5" cy="5" r="5" fill="blue" />
    </pattern>
    <pattern
      id="pattern2"
      width="10"
      height="10"
      patternContentUnits="objectBoundingBox">
      <circle cx="5" cy="5" r="5" fill="red" />
    </pattern>
  </defs>
  <rect x="0" y="0" width="100" height="100" fill="url(#pattern1)" />
  <rect x="100" y="0" width="100" height="100" fill="url(#pattern2)" />
</svg>

We can access the patternContentUnits attribute:

js
const patterns = document.querySelectorAll("pattern");

console.log(patterns[0].patternContentUnits.baseVal); // output: 1 (SVGUnitTypes.USERSPACEONUSE)
console.log(patterns[1].patternContentUnits.baseVal); // output: 2 (SVGUnitTypes.OBJECTBOUNDINGBOX)
