Hello www-svg, it is nice to see, that the formula for the y dimension is added for the feGaussianBlur. Nice as well to get now the input image for standard deviation zero. Minor cosmetic questions/suggestions: a) Why is H(x) styled in black, I(y) in red? b) Why is the approximation formula only for s available? (should be sufficient to write, that the approximation applies for the t correspondingly) c) Maybe worth to mention, that for something like stdDeviation="1 0" or stdDeviation="0 1" with '1' representing something different from 0, the mathematically expected result is not the input image. It is only a blur in one direction. However, because the definition does not explictly mention this case, implementations will hopefully do it as mathematically expected. Olaf
