I suggest that it is not treated differently than a value of zero: the filter primitive does not have any effect on the input image, the input does not get blurred. I'll change the specification text to this suggestion. >> >> Greetings, >> Dirk >> >> [1] http://www.w3.org/TR/filter-effects/#feGaussianBlurElement > > I agree with this change. Note that I would disagree with this for blur() - a negative value should be invalid at parse time. We try not to do fixup in CSS, since we have good fallback mechanisms. ~TJ
