I recently made a design with GIMP. I added a standard bevel effect to text and then ripple effect. I am trying to recreate the same effect but the ripple effect does not seem right. Is there any way to open the file and see the exact settings used for the ripple (amplitude, period, angle, phase shift, etc.)?? I may have applied a ripple effect on top of a ripple effect but don’t know. Just trying to access the filter settings used. Any help would be greatly appreciated. Thanks.

Hello!
Yesterday I received a GIMP update to version 3.0.6, but the highlights (hover) are very bad because they clash with the text color. I've already checked the preferences but haven't been able to fix it. Does anyone know how to fix this?

If you’ve ever struggled to find reliable GIMP plugins, or even if they exist? well you’re not alone. Just got back to using gimp cuz of 3.0 and again am frustrated about the finding stuff situation soo as any sane person would do I spent the last 6 hours hunting through scattered links, outdated lists, and broken downloads.
I created a comprehensive, organized, and up-to-date GIMP Plugins Catalog. Everything is neatly categorized (AI/ML, RAW tools, Filters, Automation, Scripts, Panorama, Export, and more) with essential info like supported GIMP versions, install notes, and sub-direct links (on purpose).
Check it out:
? https://github.com/XDesigns-gfx/Gimp-Plu.../README.md
? Why this matters:
- No more hunting through broken forum posts.
- Clear visibility of what works on GIMP 2.x vs 3.x.
- Quick access to documentation and “use at your own risk” warnings.
- Community-friendly: contributions are welcome! If you know a plugin that’s missing, you can add it via GitHub.
I also took care to make it readable and visually appealing, so finding the right plugin is quick and painless.
This is for anyone from hobbyists to professionals — if you’ve ever wanted an easy way to explore GIMP’s ecosystem, this is it.

Hello, how are you?
I downloaded and installed a D&B plugin in GIMP. I'm using version 3.0.6 (updated yesterday because I was on 3.0.4). The plugin is working very well and is a real help. However, I have a question: I'm facing the following situation:
1. D&B layer
2. Character layer with a transparent background
3. Solid color background layer.
It turns out that if I apply D&B to the background area, even though it's on the D&B layer, when I brush over the area, it paints over that area. Is there a way to apply the D&B layer only to the layer immediately below, that is, the character layer?
I tried locking the alpha channel on the D&B layer and the character layer, but it didn't work.
D&B = Dodge & Burn

I don't know if this will help any other beginners on Gimp 3 Python scripting.
Taking most of a day, I made a simple example that works, to my amazement. I have Gimp 3.0.4 on Ubuntu 22.04, and this runs in GIMP from Filters -> Development -> Python-Fu -> Python Console.
It draws a red box on a blue background.
Code:
import gi
gi.require_version('Gimp', '3.0')
from gi.repository import Gimp
Gimp.context_set_foreground(Gegl.Color.new("red"))
Gimp.context_set_background(Gegl.Color.new("blue"))
image = Gimp.Image.new(300, 400, Gimp.ImageBaseType.RGB)
layer = Gimp.Layer.new(image, "layer 1", 300, 400, Gimp.ImageType.RGBA_IMAGE, 100, Gimp.LayerMode.NORMAL)
image.insert_layer(layer, None, 0)
layer.edit_fill(Gimp.FillType.BACKGROUND)
Gimp.Display.new(image)
Gimp.Image.select_rectangle(image, Gimp.ChannelOps.REPLACE, 60.0, 80.0, 100.0, 150.0)
layer.edit_fill(Gimp.FillType.FOREGROUND)
Gimp.Selection.none(image)
Gimp.displays_flush()
I learned that you can also set colors in this format:
Code:
Gimp.context_set_foreground(Gegl.Color.new("#B00000"))
I found the documentation terribly sparse. For example, in https://developer.gimp.org/api/3.0/libgimp,
at https://developer.gimp.org/api/3.0/libgi...angle.html, which contains:
Code:
gboolean
gimp_image_select_rectangle (
GimpImage* image,
GimpChannelOps operation,
gdouble x,
gdouble y,
gdouble width,
gdouble height
)
My script has the line:
Code:
Gimp.Image.select_rectangle(image, Gimp.ChannelOps.REPLACE, 60.0, 80.0, 100.0, 150.0)
How I got from "gimp_image_select_rectangle" to "Gimp.Image.select_rectangle" wasn't clear, and when I looked up the constants for Gimp.ChannelOps.REPLACE,
at https://developer.gimp.org/api/3.0/libgi...elOps.html
it shows GIMP_CHANNEL_OP_REPLACE
from which it wasn't clear to me that this could be Gimp.ChannelOps.REPLACE.
I would be happy to help improve the documentation, which I found sparse and confusing.
I would be grateful if anyone could tell me how to change the dark blue font in the GIMP python console (without changing the Dark Colors scheme), because I couldn't read it at all unless I highlighted it so it showed as reverse video. I couldn't figure out where, maybe in what css file, this is defined. I'm using gnome and X11.
To do this, it was a lot of hit and miss, and searching for other people's scripts and trying to find similar code in theirs. Also, I don't really understand how to convert from pdb to non-pdb function calls and back.
I guess my next step is to convert this to a plug-in (.py) file.
