Make people metal with GEGL

GEGL is moving this entire forum into the 21st century that includes live previews, presets, and eventually non-destructive filters.

The script fu engine doesn't stand a chance against Adobe CC but GEGL does. Enjoy the new GEGL filter.

I just updated the filter to fix a typo.

Version for Gimp-2.10.30 Win 64 Bit attached.
Place the file in Gegl plugins in a directory: ... \lib\gegl-0.4\

Thank you so much MareroQ. Nice effect possible thanks to you. :coolthup

This filter is a combination of desaturate, alien map, noise reduction and hue-chroma's lightness. Other programs like Pixelitor use the term "solarization" for their Alien Map filter counter part. That is what inspired the name.

contrast, thank you so much for making GEGL Options works. :tyspin

I thanked MareroQ his adaptation to windows 64, too.

GEGL Bevel and Metallic make this

with Gimp:Colorize

Bloom and mean curvature seems to slightly improve it as well. If at least two people show interest I will make a filter of it.
Also some fonts it looks terrible

I'll get to it and I have an idea to make it four steps to justify making a filter.

NOTE TO FORUM READERS -- THIS FILTER IS GEGL:CHROME! A FILTER THAT BRANCHED FROM GEGL METALLIC! GEGL:METALLIC IS NOT A TEXT STYLING FILTER ON ITS OWN WHERE AS GEGL CHROME IS.

Requires third party GEGL:Bevel, GEGL:Metallic and GEGL:innerglow

So much hype for the filter but it is

It's too complicated to turn into a filter. The only way I can turn this into a filter is if I downgrade it and the text will have rough jagged edges worse then Glossy Balloon.

Here's the graph and it will come with multiple variations. REMEMBER, Bevel, Metallic and stand alone InnerGlow third party operations are needed for this to work

Code: Select all

median-blur radius=04 alpha-percentile=65

where would I find "bevel" ?

contrast_ · **Joined:** Oct 31, 2020 **Posts:** 1446

Bevel is part of GEGL Effects. It comes with it.

The InnerGlow that comes with GEGL Effects is not the same stand alone innerglow as the one I have on github

This is my result.
I'm still on GIMP 2.10.28 ...
The filters produce a lot of errors, maybe because of that. The results look fine though.
I'll update GIMP only when the colour picker bug is really gone.
Maybe in 2.10.34...

Good news! I reworked the graph and I know this new graph is possible to be turned into a filter. It doesn't even need innerglow. However, it will take a lot of work as it is still confusing. The final line is the hardest thing to put in the graph.

REQUIRES GEGL BEVEL AND GEGL METALLIC

Code: Select all

color-overlay value=#ffb386
bevel th=0.096 azimuth=60  radius1=3  bevel1=65  th=0.1
metallic solar1=22 solar2=53 solar3=24 light=6 smooth=2
bloom strength=18
unsharp-mask scale=0.2
softglow glow-radius=2
noise-reduction iterations=3
id=1  gegl:over aux=[ ref=1  xor aux=[  ref=1  median-blur radius=2 alpha-percentile=1    ] median-blur radius=2 alpha-percentile=55 percentile=9 gaussian-blur std-dev-x=1 std-dev-y=1  opacity value=2
 median-blur radius=3 ] 

Said final line in question is
id=1 gegl:over aux=[ ref=1 xor aux=[ ref=1 median-blur radius=2 alpha-percentile=1 ] median-blur radius=2 alpha-percentile=55 percentile=9 gaussian-blur std-dev-x=1 std-dev-y=1 opacity value=2
median-blur radius=3 ]

it is possible to put in a graph the convention way but just really tedious to get the node connections right.
