Usage notes

Value userSpaceOnUse | objectBoundingBox
Default value userSpaceOnUse
Animatable Yes
userSpaceOnUse

This value indicates that any length values within the filter definitions represent values in the current user coordinate system in place at the time when the <filter> element is referenced (i.e., the user coordinate system for the element referencing the <filter> element via a filter attribute).

objectBoundingBox

This value indicates that any length values within the filter definitions represent fractions or percentages of the bounding box on the referencing element.
