Not everything cool GEGL does can easily be made into a filter. We need to get into a habit of sharing GEGL syntax with each other to do cool things. today I will be sharing a 3d text styling effect. You must replace my home path with a path of your own. GEGL cannot link images from the internet (we tried)

Code: Select all

transform transform=matrix(1.0156650757686598,0.075701741929592628,0.000365746118200971,0.013317261513591921,1.2296272065975005,9.0806881192612718e-05,0,0,1)  first-iteration=1 iterations=0 fade-opacity=1 paste-below=no sampler-type=nohalo

Have fun.

Not so fast! You are doing a hell of a job so far!

Hell yes! I cannot agree more.

@contrast_ You are doing an absolute great job, thank you so much :tyspin

Thank you all. But seriously this filter won't happen because GEGL cannot call Gimp's 3d transform unless Gimp is rebuilt from source.

Did you tried with the other transform tool like the unified transform tool?
Or the Filters/Map/Recursive transform... (with "First iteration" set at 1 and "Iterations" set at 0), because it's a filter, maybe it can work?

No it will not work and I tried exactly that with recursive transform. I forked recursive transform and it had a dialog with numbers and the words "transform" with no on canvas abilities. I was wondering where the on canvas transform was. A gimp dev then explained that transform and gradients on canvas are controlled by Gimp (not GEGL). GEGL does the image processing while Gimp does on canvas tools. Only certain filters are white listed to use on canvas tools.

I'm upset because of that. This also prevented me from making a border filter by forking vignette. We can't work around this unless there is a way to patch Gimp or we have the guts to rebuild it with white list permissions on new filters.

Recursive Transform is a white listed transform filter and Vignette and Supernova is a white listed on canvas gradient. The gradient is heavily modified though by other operations.

Code: Select all

id=2
xor aux=[ ref=2 id=1
gegl:svg-luminancetoalpha aux=[ ref=1  ] invert-transparency  ]

color-to-alpha color=#000000

Extract the brighthest colors from a layer. (This requires my custom Invert Transparency filter)

Code: Select all

gimp:desaturate
invert-gamma
id=1
gimp:layer-mode layer-mode=hsl-color aux=[ ref=1 color-overlay value=#ffa2f8 ]
softglow brightness=0.1
bloom radius=3

exposure black-level=6 exposure=-0.4
noise-reduction
id=2
multiply aux=[ ref=2  ]

Glow Stick Effect. You can change the color by changing `color-overlay value=`

This operation blurs rough edges. It is similar to convulve stroke (set to blur). It requires my custom inner glow filter.

Code: Select all

id=1
gimp:layer-mode opacity=100  layer-mode=split blend-space=auto composite-mode=auto composite-space=auto  aux=[  ref=1  innerglow grow-radius=6  radius=5 value2=#000000    ] 


dst-over aux=[ ref=1 box-blur radius=1 median-blur radius=2   ]  

I want to make this into a filter but I don't know how to link

Code: Select all

Gimp:layer-mode.

Inner glow radius adjust the blur.

Requires my custom hidden operation MCOL which comes with GEGL Effects and several other of my third party filters. This graph puts the rgb channels next to each other as layers, slightly moves themn and then adds glitch and scanline effects.

Here is the graph to do this. It requires a top and bottom layer import to GEGL Graph.

Top Layer

Code: Select all

hue-chroma hue=33 chroma=5 lightness=-3

Bottom Layer

Code: Select all

lens-distortion main=80 zoom=6
color-overlay value=#007dff
id=1  ref=1 motion-blur-zoom center-y=0.5 center-x=0.5 factor=-7.0
gegl:opacity value=1
