A filter

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:

Code: Select all

#@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 :oops:

but it works, I think).
Sorry for my English.

Thanks, I'll add it in few days (I'm away from my computer until Monday)

Like your result of your new preset. Not sure (I'm a GIMPer; not a coder) how to run it without it being a part of the G'MIC GIMP plugin. I tried to copy/paste in the code box inside G'MIC's code box within the plugin itself, but it didn't run. I'll await David to enter the code as a custom preset of yours. Looking forward to trying it out myself.

Thank you Ronounours. ^^ Oh, since I'm here, I wanted to say thank you for your work; colorize[interactive] is a real time saver, I love it.

Lylejk, in the codebox using the default values the commands are:

Code: Select all

--polygonize 35,10,10,10,10
--blend[0,1] alpha,0.5
-texturize_canvas[2] 50,0.5,0.6
-smooth[2] 50,0.4,0.7,2,5
--plasma[2] 0.7,100,8 -n 0,255
-blend[3,2] grainmerge,0.3
-bilateral[0,2] 10,7
-blend[0,2] alpha,1
-rm[-1]

Thanks Corvo; that works great. Do look forward to the preset for the additional tweaks that will be enabled. Thanks for the preview.

Thank you to all ^^
Another example of the filter in action.

With some colour corrections; gradient norm to extract and preserves the edges of the original image; some adjustment and the sky painted quickly with krita.

Belated thanks, Corvo and David. A very nice filter to play with. I added G'MIC patterns-paper texture to further accentuate the painting texture.

@Corvo
Not bad! We should all be this good when we don't know what we're doing. It would simplify life a great deal.
