]If you request an algorithm that wasn't calculated for the image:
[

]Example SVG Mask
How to embed SVG mask or image to HTML
Without JavaScript
Using object tag, just insert the generated signed URL into data attribute.
✅ Pros: Retains SVG scalability and interactions.
❌ Cons: Limited browser support and no direct CSS styling.
<object
type="image/svg+xml"
data="https://storage.googleapis.com/...">
</object>With JavaScript
Download SVG content from the signed URL and inject it into your div container.
✅ Pros: Allows direct manipulation via CSS and JS.
❌ Cons: Requires JavaScript to fetch and insert the SVG.
<div id="svg-container"></div>
<script>
fetch("https://storage.googleapis.com/...")
.then(response => response.text())
.then(data => {
document.getElementById("svg-container").innerHTML = data;
});
</script>CSS mask customization example
For example I have the svg mask for eye bags algorithm.
The mask consists of 3 masks actually:
eye_bags-dark_circles_mask(yellow)eye_bags-eye_bags_mask(green)eye_bags-lacrimal_grooves_mask(white)
And it will look like this:
For example, I would like to override the fill color of eye_bags-eye_bags_mask.
In order to achieve it, I need to add this CSS rule:
polygon.vectorEffectClass.eye_bags-eye_bags_mask {
fill: blueviolet;
}So the result would look like this:
