primitiveUnits property

  • Article

Specifies the coordinate system for the various length values within the filter primitives and for the attributes that define the filter primitive subregion. The filter primitives identify a subregion which restricts calculation and rendering of the given filter primitive. The default filter primitive subregion is equal to the filter region. If primitiveUnits="userSpaceOnUse", all attributes represent values in the current user coordinate system that is in place at the time when the filter is referenced. If primitiveUnits="objectBoundingBox", then all attributes represent fractions or percentages of the bounding box on the referencing element. If attribute primitiveUnits is not specified, then the effect is the same as specifying a value of "objectBoundingBox".

This property is read-only.
