Please add additional information to this bug (preferably as a test case). 30178 2 oliver 2006-01-26 15:30:06 -0800 If you compare the svg http://www.w3.org/TR/2002/CR-SVG11-20020430/images/filters/filters01.svg to the expected output: http://www.w3.org/TR/2002/CR-SVG11-20020430/images/filters/filters01.png You can see that there is a significant difference in the highlights -- in the svg the highlight is towards the bottom of the rendered image. In the png it is towards the top. There are some not insignificant differences in the overall colour of the rendered image, but i'm currently attributing these to a combination of colour matching and a slightly incorrect gaussian blur. 30186 3 eric 2006-01-26 15:44:17 -0800 Marking this as a P4 as this is not a very user-visable issue. 66267 4 eric 2008-01-05 00:56:01 -0800 *** Bug 16714 has been marked as a duplicate of this bug. *** 245213 5 zimmermann 2010-07-01 02:13:09 -0700 This is long invalid. We don't even have the CI based filters anymore.
