html - Convert SVG path data to 0-1 range to use as clippath with objectBoundingBox

Question

I'm using a rather complex SVG shape exported from Illustrator as a clipping path.

The problem is that objectBoundingBox requires path data to be within the 0-1 range, and my path contains path data out of this range. Here is what I'm using:

<svg>
  <clippath id="clipping" clipPathUnits="objectBoundingBox">
    <path d="M228.6,94.8L176.8, 5.5c-2-3.5-5.8-5.5-9.9-5.5H63.2c-4.1, 0-7.8, 1.9-9.9,5.5L1.5,94.9c-2, 3.5-2,7.8,0, 11.4       l51.8, 89.8c2,3.5, 5.8,5.9,9.9,5.9h103.7c4.1, 0, 7.8-2.4,9.9-6l51.8-89.7C230.7, 102.8,230.7, 98.3,228.6,94.8z M192.8,104.4l-35.5, 
      61.5c-1.4,2.4-4,4.1-6.8, 4.1h-71c-2.8,0-5.4-1.7-6.8-4.1l-35.5-61.4c-1.4-2.4-1.4-5.5,0-7.9l35.5-61.5c1.4-2.4,4-4.1,6.8-4.1h71c2.8, 0, 5.4,1.7,6.8,4.1l35.5, 61.4C194.2,98.9, 194.2, 102, 192.8, 104.4z"/>
  </clippath>
</svg>

Is there an easy solution to convert this to the 0-1 range so that I can use objectBoundingBox?

RE: Comment. I am able to apply any number of transforms to the SVG element, but it still doesn't work with objectBoundingBox. For example:

<clippath id="clipping" transform="scale(1,1)" clipPathUnits="objectBoundingBox">

Answer 1

Following the comments from @Robert Longson, just transform the scale of the <clipPath>.

The shape I have taken from Figma for this example is 248 x 239, so I just apply the equivalent scale(1/248, 1/239). This gives:

transform="scale(0.004032258064516, 0.00418410041841)"

This along with clipPathUnits="objectBoundingBox" means that we can use this shape to clip at any size or aspect ratio.

.clipped {
  clip-path: url(#clip-shape);
}


/* make sure the svg doesn't take up any space in the document */

svg {
  width: 0;
  height: 0;
}

p {
  width: 200px;
  color: white;
  background: blue;
}

<!-- Note: SVG width & height have no effect here, but I've left them for reference -->
<svg width="248" height="239">
  <defs>
    <clipPath id="clip-shape" clipPathUnits="objectBoundingBox" transform="scale(0.0040, 0.0042)">
<path d="M199 30C110 36 2.03409 -46.9894 18 43C29 105 -7.39156 155.325 1.99998 197C18 268 69.8645 202.231 170 237C242 262 288 24 199 30Z" />
    </clipPath>
  </defs>
</svg>
