Post subject:  Get use to using GEGL Graph syntax.I can't make a filter of everything
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)

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.

Post subject:  Re: Get use to using GEGL Graph syntax.I can't make a filter of everyt
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?

Post subject:  Re: Get use to using GEGL Graph syntax.I can't make a filter of everyt
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.

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

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.
