We have a new plugin called GEGL pipes. Its the second GEGL plugin of 2026 because I never released the first one yet :oops:

I need to know if it works on GIMP 3.2

LOCATION TO PUT BINARIES

Windows

Code: Select all

C:\Users\(USERNAME)\AppData\Local\gegl-0.4\plug-ins

Linux

Code: Select all

~/.local/share/gegl-0.4/plug-ins

Linux(Flatpak includes Chromebook)

Code: Select all

~/.var/app/org.gimp.GIMP/data/gegl-0.4/plug-ins

If you compile it from source lemme know but I'd prefer to know if the binaries work

The Linux Binary was compiled against GEGL 0.4.67
The Windows Binary was compiled against GEGL 0.4.48 quasi-mysys2

both on X64 Fedora Linux

Look in Filters>Render>Fun to find it or search "pipes"
then restart GIMP and go to "GEGL operation" to find the new plugin

Have fun everyone, its really important I know if this works in RC2 :coolthup

Alway up for a test

Kubuntu 24.04 / Gimp 3.2.0 RC2 (appimage from gimp.org) and it works ok.

Thank you for the new filter.

Unfortunately, it doesn't work for me in Gimp 3.2 RC2 (Win10).
gegl-0.4\plug-ins\metalpipes.dll: The specified procedure could not be found.

Works in Gimp 2.10.38 and 3.0.6.
Also works in RasterFlow :yes

In rasterflow its missing many gimp: nodes.

My plugins work on GIMP 3 RC2 on Linux compiled against GEGL 0.4.62 and or 0.4.67

the problem is Windows compiled against 0.4.48. I don't know how to get GEGL 0.4.67 on Windows, but it could also be the possibility Windows is blocking something, innfact I already knew they worked on RC2 Linux I just wanted to double check.

Try to compile GEGL on Windows using this

Greatly appreciated, Yeah its a Windows thing, It needs to be recompiled for Windows and I don't know how to do it.

Another nice filter!

It runs smoothly here, even in AppImages Gimp 3.2 RC2 from gimp.org and from ivan-hc Continuous GIT.

Many thanks contrast_ !

I compiled pipes.c with gegl-0.4.62 (this is my msys64/mingw64 version installed for Gimp 3.0.4).
It still doesn't work.

I updated Gegl to version 0.4.66-1 and recompiled.
The filter still doesn't work.

What does it say in the cli?

Do his plugins work (Flatscrew)?

It makes no sense they work fine on Linux

Tell me if this works on Windows its 0.4.48 but Grok attempted to "fix it"
This is a DLL file precompiled

He and DeepSeek both said its possible windows interprets GEGL graphs in a different way

This latest version also didn't work in Gimp 3.2 RC2 for Win10.

For testing purposes, I downloaded:
https://github.com/flatscrew/plugins-linux-beaver
The compilation went smoothly, but the filters don't work in Gimp 3.2 RC2.

Those included in the RasterFlow installer work in Gimp 3.2 RC2 for Win10.

My conclusion is that my compilation environment is incorrect.
I couldn't find any information on how Flatscrew compiled plugins-linux-beaver.

Does he put them in the same directory that you put your plugins in, or a different one? We have to figure out what he is doing.

I ran vimdiff and his plugins are the same code outside of a few changes he made to irrelevant category areas in some of them. So either its the compilation environment or he puts them in a different folder. They work on Linux atleast with no issue.

Hi contrast_, Just to mention Imgur blocks all access from the United Kingdom so anyone in the UK won't see the images you put in post #1.

Ok, I'll use a dif image host. Can someone test if my plugins work on GIMP 3.0.8, (Linux and Windows) they should as nothing changed. I'm just too lazy to check

@_contrast , 'golden pipe' whistles here as a golden pipe!

Well at least we can still use them in Windows 11 Gimp-2.10.38 RC versions.

MareroQ, i tried PMing you about Rasterflow. Can you tell me how you compiled it?
Thanks!

2.10.38 isn't non-destructive.

Does pipes work on Windows on 3.0.8?

Whatever the hell is going on is confirmed to be a compilation enviorment issue. They work on Windows but I am compiling them in a unallowed way. I think the binaries need to be signed or something, but I'm just guessing.

Perhaps Grok and DeepSeek can figure it out. Though I can't test because I don't have Windows.

Hi Rod,

The Windows installer version RasterFlow-0.1.5-Setup-win64.exe doesn't work for you?

https://github.com/flatscrew/rasterflow ... tag/v0.1.5

RasterFlow (v0.1.6) compiles without problems on msys64/mingw64 according to the author's guide.

Only libgtkflow and libgflow need to be compiled from source, while the remaining required dependencies can be installed using pacman:
