32 * Lightness (0->50, default 5) -> convolve (kernelMatrix, central value -1000->-1050, default -1005)
33 * Smoothness (0.01->10, default 0.7) -> blur2 (stdDeviation)
34 * Dilatation (3->100, default 6) -> colormatrix3 (n-1th value)
36 * Blur (0.01->10., default 5.) -> blur3 (stdDeviation)
37 * Blur spread (3->20, default 6) -> colormatrix5 (n-1th value)
38 * Blur erosion (-2->0, default -2) -> colormatrix5 (nth value)
40 * Stroke color (guint, default 205,0,0) -> flood2 (flood-opacity, flood-color)
41 * Image on stroke (boolean, default false) -> composite1 (in="flood2" true-> in="SourceGraphic")
42 * Image on stroke opacity (0.->1., default 1) -> composite3 (k3)
43 * Fill color (guint, default 255,203,0) -> flood3 (flood-opacity, flood-color)
44 * Image on fill (boolean, default false) -> composite2 (in="flood3" true-> in="SourceGraphic")
