I was trying to simplify shapes and give a painterly feeling to a picture, after some trial and error I come up with this code:
#@gimp corvo's painting_5 : gimp_corvo_painting_5, gimp_corvo_painting_5(0)
#@gimp : note = note("Polygonize settings")
#@gimp : Amplitude = int(35,0,2000)
#@gimp : Smoothness = float(10,0,100)
#@gimp : Minimal area = float(10,0,100)
#@gimp : Alpha Polygonize = float(0.5,0,1)
#@gimp : sep = separator()
#@gimp : Texture = float(50,0,100)
#@gimp : Plasma= float(0.3,0,1)
#@gimp : sep = separator()
#@gimp : note = note("Smooth settings")
#@gimp : Amplitude = float(50,0,1000)
#@gimp : Gradient smoothness = float(2,0,10)
#@gimp : Tensor smoothness = float(5,0,10)
#@gimp : Alpha Filter= float(1,0,1)
gimp_corvo_painting_5 :
--polygonize $1,$2,$3,10,10
--blend[0,1] alpha,$4
-texturize_canvas[2] $5,0.5,0.6
-smooth[2] $7,0.4,0.7,$8,$9
--plasma[2] 0.7,100,8 -n 0,255
-blend[3,2] grainmerge,$6
-bilateral[0,2] 10,7
-blend[0,2] alpha,$10
-rm[-1]
The same result can probably be achieved with something simpler (I don't really know what I'm doing
but it works, I think).
Sorry for my English.
