SVGPatternElement: preserveAspectRatio property
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The preserveAspectRatio read-only property of the SVGPatternElement interface reflects the preserveAspectRatio attribute of the given element. It defines how the pattern's content should be scaled to fit the given space, preserving its aspect ratio.
Value
An SVGAnimatedPreserveAspectRatio object.
Example
Given the following SVG, we can use the preserveAspectRatio property to retrieve the scaling behavior for the pattern element:
html
<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 200 200">
<defs>
<pattern
id="pattern1"
width="10"
height="10"
preserveAspectRatio="xMidYMid meet">
<circle cx="5" cy="5" r="5" fill="blue" />
</pattern>
</defs>
<rect x="0" y="0" width="100" height="100" fill="url(#pattern1)" />
</svg>
We can access the preserveAspectRatio attribute:
js
const pattern = document.querySelector("pattern");
console.log(pattern.preserveAspectRatio.baseVal); // output: SVGPreserveAspectRatio {align: 1, meetOrSlice: 1}
