The SVG_SET_FILTER command can be used to associate a filter with the object having the svgObject reference. If svgObject is not a valid reference, an error is generated. If the attribute already exists, its value is replaced.
The url parameter is the name of the filter to be used as specified by the SVG_Define_filter command. If this name does not exist, an error is generated.
See the SVG_Define_filter command.
