This thread shows me editing non-destructively in CMYK Student's special Gimp Build.

I built CMYK Student's Gimp 2.99.17 from source today and now I am testing non-destructive GEGL filters. Let me just say that it is AMAZING and I ADORE every second of this, but I still found some bugs. I will be posting in this thread to show off the non-destructive editing potential in CMYK Student's special build of Gimp 2.99.17. It works with my plugins obviously.

A GEGL Graph running non-destructive



My Sparkle plugin running non-destructive with the linear light blend mode.

The rectangle select tool and other tools like it can make selections and then we can apply GEGL filters non-destructively, but what is very impressive is that GEGL remembers where the selection is applied.

In this picture the Edge Detect filter (Edge) and a orton glow filter (Bloom) are both on the same layer and selections
that were made with Gimp's Rectangle Select tool are remembered.

Non-destructive editing has a bug where it does not remember the previous color of a filter when you go back to editing it. I reported it above and wrote.

In example I start a non-destructive GEGL Drop Shadow and change its default color from black to red, when I go to re-edit it it will go back to being black. This can be worked around by loading the most recent preset (to bring the red back) but I still this is a bug that needs to be fixed.

Example of GEGL Effects non-destructive and editable.


When edited it goes back to its default colors



This can be fixed by running a recent preset obviously.

Here is an example of individual non-destructive effects in the special Gimp 2.99.17 build. I used color overlay, my plugin bevel and two drop shadows. You can learn more about individual effects and how to use them in Gimp 2.10 (destructively) here

Bevel is blended with the blend mode "grain merge" but it doesn't show that.

Here is it being edited.

I just realized something I cannot apply a filter in the middle of other effects without applying on top it and moving it down.
In example lets say these two filters are in a non-destructive Gimp layer GEGL Graph


gaussian-blur
bloom

and I want to put cubism in the middle for whatever reason.

I first have to do


cubism
gaussian-blur
bloom

then move it down one.

cubism

It is interesting how Gimp's team made non-destructive editing in Gimp 2.99.17. The usual glitches that exist in Gimp's GEGL Graph are not present here.

Let me explain what is going on. In a nutshell each "layer effect" or "smart filter" whatever you want to call it is a GEGL graph of its own. Here is a pic of all the effects.


This text style can be written in GEGL syntax the usual way I do it like with a median-blur radius=0 to reset the GEGL graph from bugs.


But this is how Gimp's team does it in non-destructive editing. They use a way to separate graphs entirely.

This is really really NICE! I am so looking forward to trying it.

Here is a video of my plugin "glossy balloon" being used as a brush.

Download to Glossy Balloon is here but note it is destructive in Gimp 2.10 and normal 2.99

I filed a new bug for 2.99 NDE build here about missing features.

My bash plugin that calls GMIC and AIs is not capable of working proper in CMYK students Gimp 2.99.17 unless it is the first effect applied. This is because the bash plugin makes a image file copy of the layer, it does not make an image copy of the original image before the effects were applied. And even if it did do that it would cancel other effects. In this case the bash plugin uploads /tmp/out.png and if other effects are removed they will still be present because the bash plugin loaded a static image file showing when the now removed effects are still present. In example lets say we have.


Bash to call GMIC and AI
Saturation


Bash loads a copy of the layer with saturation. If saturation is removed from the "layer effects" list it will still be present in the /tmp/out.png that is loaded. If the problem was in reverse loading GEGL bash would cancel all other effects that came before it and remove saturation. There is no way to solve this problem.

However once again if it is like


dct-denoise
saturation
bloom
unsharp-mask
bash to call GMIC and AI


things will work fine because the Bash plugin is at the bottom of the list. This is a natural consequence of how the bash filter works and it is not a bug. Just something I didn't expect. The only way this could be fixed is if we find a way to caculate GMIC filters and AIs which would be ALOT MORE DIFFICULT THEN EXPORTING A PNG FILE.

I just posted a 9 minute video (8 minutes and 50 seconds minutes actually) of me editing non-destructive in Gimp on Reddit.
I am editing a picture of my old family cat and using native Gimp filters like (curves, saturation, gaussian blur) and my plugins GEGL Effects and Sparkle.

Filters cannot be individually disabled yet, but they can be "hack-disabled" by setting them to the behind blend mode.

I guess this won't work on images with transparency and filters that generate rendered fills (like cell noise and spiral). In that case set their opacity to 0.

Here is my plugin "Glass Metallic Marble" being ran with curves on top of it. Curves cannot be ran inside GEGL Graph so this is an interesting thing I have going on.

The same "layer effects" from this image were applied to two other images by selecting and deleting the coffee girl and merging a floating point on the layer she was on.


These two images below take the "layer effects" that were on the girl.

For those that like adjustment layers (i.e, non-destructive editing), this is cool. I'm a gonzo editor so to each his/her own. Still, cool stuff, contrast_.

Here is me applying Kalidescope, Hue rotation, Gaussian Blur and Sharpen together as "layer effects".



I'm surprised this thread isn't exploding in popularity considering all the hype with non-destructive editing in Gimp 3.2.

It has exploded into popularity with me - I'm fixated on it - but until I can get an appimage, I can't really join in.

Erisian No worries! Unless something really bad happens, this feature is scheduled to be included in the 2.99.18 release which should becoming out in roughly a week or so. It's been great seeing how _contrast has made use of this in their work and demos!

so glad to hear, I didn't know that! But it is cool knowing I am a week ahead of everyone else.

ok, I just confirmed that my bash plugin that can call AI and GMIC filters does not allow editable text with CMYK Student's build. If you try to edit the text it shows the text box but no matter what you type nothing happens. It only shows the original text that the filter was applied on. The reason why this happens is obvious, because the text is an imported png from GMIC or whatever other app outside of Gimp. GEGL text is editable because GEGL is actively running on the text layer. The imported bash command is just GEGL importing a png from the /tmp/ folder.
