The k2
attribute defines one of the values to be used within the arithmetic
operation of the <feComposite>
filter primitive.
The pixel composition is computed using the following formula:
result = k1*i1*i2 + k2*i1 + k3*i2 + k4
You can use this attribute with the following SVG elements:
Example
<svg viewBox="0 0 420 200" xmlns="http://www.w3.org/2000/svg">
<filter id="composite1" x="0" y="0" width="100%" height="100%">
<feComposite in2="SourceGraphic" operator="arithmetic" k1="1" k2="1" k3="0" k4="0" />
</filter>
<filter id="composite2" x="0" y="0" width="100%" height="100%">
<feComposite in2="SourceGraphic" operator="arithmetic" k1="1" k2="10" k3="0" k4="0" />
</filter>
<image href="mdn.svg" x="0" y="0"
width="200" height="200" style="filter: url(#composite1);" />
<image href="mdn.svg" x="0" y="0"
width="200" height="200" style="filter: url(#composite2); transform: translateX(220px);" />
</svg>
