The clipPathUnits attribute indicates which coordinate system to use for the contents of the {{ SVGElement("clipPath") }} element.
You can use this attribute with the following SVG elements:
html,
body,
svg {
height: 100%;
}
<svg viewBox="0 0 100 100">
<clipPath id="myClip1" clipPathUnits="userSpaceOnUse">
<circle cx="50" cy="50" r="35" />
</clipPath>
<clipPath id="myClip2" clipPathUnits="objectBoundingBox">
<circle cx=".5" cy=".5" r=".35" />
</clipPath>
<!-- Some reference rect to materialized to clip path -->
<rect id="r1" x="0" y="0" width="45" height="45" />
<rect id="r2" x="0" y="55" width="45" height="45" />
<rect id="r3" x="55" y="55" width="45" height="45" />
<rect id="r4" x="55" y="0" width="45" height="45" />
<!-- The first 3 rect are clipped with userSpaceOnUse units -->
<use clip-path="url(#myClip1)" href="#r1" fill="red" />
<use clip-path="url(#myClip1)" href="#r2" fill="red" />
<use clip-path="url(#myClip1)" href="#r3" fill="red" />
<!-- The last rect is clipped with objectBoundingBox units -->
<use clip-path="url(#myClip2)" href="#r4" fill="red" />
</svg>
{{EmbedLiveSample("Example", '100%', 200)}}
