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.
