Could you possibly share some images processed with this software? I looked at the link but feel unsure what software is primarily aimed at.
This is actually quite cool, a nodal editor in GTK4 using GEGL (the new engine powering GIMP).
This is an independent program.
Can install carefully umnie caused conflicts with GIMP
Many thanks to the program’s author.
Two small comments:
- The RasterFlow installer interferes with the Windows registry:
which, as Zbyma72ge reported, causes conflicts with Gimp:
Would a rasterflow.ini file be possible instead?
- Too few parameters in gegl graphs.
A simple example:
Would it be possible to access all the parameters of the gegl filter, as you so brilliantly solved for G’MIC?
I can’t wait for the next version for Windows. 
The issue was also reported here:
Hi @MrQ
Many thanks for reporting it!
I will try to resolve it ASAP. As it comes to number of parameters - please resize the node by holding lower right corner 
Also: when you hold ctrl on the keyboard you can use mouse scroll to resize whole canvas and middle mouse button to pan.
can you look at my gtkflow bug?
Ah, I know what is wrong 
Sorry but there is a bit of a garbage in the repo… so, first you need to build this:
then this:
And it should be much better 
shouldnt the build system then whine at me that the library is missing?
Hm, okay, the error is kinda different:

Please set -Denable_valadoc to false:

this should help
that fixed it.
I have a question though … all the other libraries you mentioned are available in that libgtkflow repository. are you in the process of splitting them up in subprojects?
@darix the plan is to leave libgtkflow repo as it is and continue adding new features and changes into libgflow and libgtkflow4 repos.
Hi Łukasz,
Thank you for the additional information and the new version of this brilliant program.
Do You plan to add G’MIC filters, and when?
You have solved the problem with the conflict with GIMP.
I encountered problems with RasterFlow 0.1.5 (perhaps only on my Win10 computer), but I solved them in my own amateur way.
After installing and running it, the program icon appears in the taskbar, but I can’t maximize it:
I checked the registry and deleted that entry.
Restarted it, and the normal window appears:
However, the program freezes:
After diagnosing which files had changed since version 0.1.2, I replaced libadwaita-1-0.dll and libgtk-4-1.dll with version 0.1.5.
Now RasterFlow 0.1.5 works normally:
with the exception of “About.”
I don’t know if this will be of any use to you. 
Ohh… interesting ;D I need to have a closer investigation on windows then, thanks for checking out!
And btw, g’mic filters will come soon
This is very good news for Win10 users.
I apologize for the confusion and for reporting the issue (which no one has confirmed, so I suspect the problem is unique to my computer).
