If provided, filterRes indicates exactly how many pixels in X and Y are used for computation of the intermediate offscreen bitmaps. It thus defines a particular resolution at which the filtering is performed. If it is not provided, the user agent picks a suitable resolution appropriate to the output device.
Here's a filter element that defines a filterRes attribute.
<filter id="edgeFilter"> <feConvolveMatrix filterRes="100 100" style="color-interpolation-filters:sRGB" order="3" kernelMatrix="0 -1 0 -1 4 -1 0 -1 0" preserveAlpha="true"/> </filter>
