Change SVG path data into a range of 0 to 1 in order to utilize it as a clip path with objectBoundingBox

Question

Change SVG path data into a range of 0 to 1 in order to utilize it as a clip path with objectBoundingBox

My SVG shape, exported from Illustrator as a clipping path, is quite complex.

The issue I'm facing is that objectBoundingBox restricts path data to the 0-1 range, but my path data exceeds this range. Here is the current code 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>

I'm looking for a simple way to convert this path data to fit within the 0-1 range so that I can utilize objectBoundingBox. Any suggestions?

Regarding the comments, I have attempted various transformations on the SVG element, like:

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

Answer №1

After receiving feedback from @Robert Longson, I have adjusted the scale of the <clipPath>.

Utilizing a shape derived from Figma with dimensions of 248 x 239, I have applied a scale factor of (1/248, 1/239) to achieve the desired result:

transform="scale(0.004032258064516, 0.00418410041841)"

In addition, setting

clipPathUnits="objectBoundingBox"

enables the shape to be used for clipping at varying sizes and aspect ratios.

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

/* Ensure the SVG does not impact document layout */

svg {
  width: 0;
  height: 0;
}

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

<!-- Note: SVG width & height do not affect layout, retained for clarity -->
<svg width="248" height="239">
  <defs>
    <clipPath id="clip-shape" clipPathUnits="objectBoundingBox" transform="scale(0.0040, 0.0042)">

Use this PHP script to convert the paths:

$absolute_path = "M46.9819755,61.8637972 C42.0075109,66.8848566 35.0759468,70 27.4091794,70 C12.2715076,70 0,57.8557238 0,42.875 C0,32.9452436 5.3914988,24.2616832 13.4354963,19.534921 C14.8172134,8.52285244 24.3072531,0 35.8087666,0 C43.9305035,0 51.0492374,4.2498423 55.01819,10.6250065 C58.2376107,8.87215568 61.9363599,7.875 65.8704472,7.875 C78.322403,7.875 88.4167076,17.8646465 88.4167076,30.1875 C88.4167076,32.1602271 88.1580127,34.0731592 87.6723639,35.8948845 L87.6723639,35.8948845 C93.3534903,38.685457 97.2583784,44.4851888 97.2583784,51.1875 C97.2583784,60.6108585 89.5392042,68.25 80.0171204,68.25 C75.4841931,68.25 71.3598367,66.5188366 68.2822969,63.6881381 C65.5613034,65.4654463 62.3012892,66.5 58.7971106,66.5 C54.2246352,66.5 50.0678912,64.7384974 46.9819755,61.8637972 Z";

Make sure to adjust the width and height variables based on your specific bounding box.

In an effort to tackle this issue, I created a converter tool on CodePen. This tool draws inspiration from skywlkrs' solution but includes support for exponential floats and introduces some user interface enhancements:

Link to the Converter Tool

For instance, it can convert the following path:

M11.214377,3.55271368e-15 L64,0 L64,64 L11.214377,64 L1.88513642,41.4772208 C-0.628378807,35.4090582 -0.628378807,28.5909418 1.88513642,22.5227792 L11.214377,3.55271368e-15 Z

to

M0.17522,0 L1,0 L1,1 L0.17522,1 L0.02946,0.64808 C-0.00982,0.55327 -0.00982,0.44673 0.02946,0.35192 L0.17522,0 Z

It's worth noting the presence of exponents in some of the floating-point numbers due to how Sketch exports them.
