filterRes

Take care when assigning a non-default value to this attribute. Too small of a value may result in unwanted pixelation in the result. Too large of a value may result in slow processing and large memory usage.
Note that negative values or zero values disable the rendering of the element which referenced the filter.
You can use this attribute with the following SVG elements:
