{{APIRef("SVG")}}
The in2 read-only property of the {{domxref("SVGFEBlendElement")}} interface reflects the {{SVGAttr("in2")}} attribute of the given element.
An {{domxref("SVGAnimatedString")}} object.
In this example, two {{SVGElement("feBlend")}} elements are defined in a filter, each with a different in2 attribute.
<svg viewBox="0 0 200 200" xmlns="http://www.w3.org/2000/svg">
<filter id="blend-filter">
<feBlend in="SourceGraphic" in2="SourceAlpha" operator="over" />
<feBlend in="SourceGraphic" in2="BackgroundImage" operator="in" />
</filter>
<rect
x="20"
y="20"
width="100"
height="100"
fill="red"
filter="url(#blend-filter)" />
<circle cx="100" cy="100" r="50" fill="blue" filter="url(#blend-filter)" />
</svg>
We can access the in2 attribute:
const feBlends = document.querySelectorAll("feBlend");
console.log(feBlends[0].in2.baseVal); // Output: "SourceAlpha"
console.log(feBlends[1].in2.baseVal); // Output: "BackgroundImage"
