bias
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2020.
The bias attribute shifts the range of the filter. After applying the kernelMatrix of the <feConvolveMatrix> element to the input image to yield a number and applied the divisor attribute, the bias attribute is added to each component. This allows representation of values that would otherwise be clamped to 0 or 1.
You can use this attribute with the following SVG elements:
Usage notes
| Value | <number> |
|---|---|
| Default value | 0 |
| Animatable | Yes |
One application of bias is when it is desirable to have 0.5 gray value be the zero response of the filter.
