« SVG Attribute reference home

The radius attribute represent the radius for the operation on a given <feMorphology> filter primitive. If two <number>s are provided, the first number represents a x-radius and the second value represents a y-radius. If one number is provided, then that value is used for both X and Y. The values are in the coordinate system established by the primitiveUnits attribute on the <filter> element.

If the attribute is not specified, then the effect is as if a value of 0 were specified.
