Proposals/Hit testing
This is a proposal for an API that can help with hit testing of the different parts of an element – fill, stroke and markers – separately.
[Constructor(UIEvent event, optional Element context)] interface SVGPoint { ... }; dictionary MarkerDetails { long index; SVGMarkerElement? element; float position; }; interface SVGLocatable { bool isPointInFill(SVGPoint point); bool isPointInFill(UIEvent event); bool isPointInStroke(SVGPoint point); bool isPointInStroke(UIEvent event); bool isPointInMarker(SVGPoint point, optional unsigned long index); bool isPointInMarker(UIEvent event, optional unsigned long index); MarkerDetails getMarkerFromPoint(SVGPoint point); MarkerDetails getMarkerFromPoint(UIEvent event); MarkerDetails getMarkerAtIndex(unsigned long index); };
Can we make pointer-events="painted" or "all" mean markers too? Or do we need a new property for that?
