bias
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.
