primitiveUnits - SVG: Scalable Vector Graphics 编辑
The primitiveUnits attribute specifies the coordinate system for the various length values within the filter primitives and for the attributes that define the filter primitive subregion.
Only one element is using this attribute: <filter>
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 afilterattribute). - objectBoundingBox
This value indicates that any length values within the filter definitions represent fractions or percentages of the bounding box on the referencing element.
