Hi GIMP developers,

Love the new release! I'm giving GIMP 3.0.2 a try, and I noticed something that might be a bit confusing, especially for new users. In the Layers dock, when you right-click to delete a layer, the context menu options could be a little clearer.

I found myself pausing before clicking "Delete Layer" because it wasn't instantly apparent that it would only delete the layer I had currently selected. While experienced users will likely know this, someone new to GIMP might be concerned about accidentally deleting more than they intend.

It didn't cause me any real issue, but I thought it was worth mentioning. A small tweak to the wording to make it more specific could make the interface even more intuitive. Keep up the great work!

Edit: 20:41, 1 Apr 2025
I have found a solution, there is cross icon in layer dock, you dont have to right click on layer, just select layer and click on cross icon.

The original reference is a vector.

The simplest approach to this that I've achieved so far is to use the pathing tool to create some triangular spikes, but I am having a difficult time recreating these sort of U shaped pointy edges with curves bottom shapes. Am I on the right path using the Pathing Tool?

As title suggests, Gimp 3.0 is installing without my permission. This has happened over 3 times and it is really bothering me as its happening by itself. I am using windows 10 and i have gimp 2.10 and gimp 2.6 installed on my computer none of which i want to update.

I’m currently in the middle of a project that I’m hoping to automate and I think the best way to do it would be to iterate through each color on one layer.

However, the colors on this layer aren’t neatly arranged - is there a way, in the UI or the script, to use the select by color tool without having to take a sample from the image? So just saying “select all the pixels that are #B3C3DD” instead of clicking.

Using Gimp 3 on Linux with a Wacom Intuos.

I'm not sure what happened but whenever I hover my pen above the tablet it starts drawing which is not what I want--I only want it to start drawing if I actually make contact with the tablet. On the KDE systems settings I have the tablet set to "defer to application" for both pen buttons.

While applying an effect, I will see the fx button popup next to my layer where I should be able to re-edit those applied effects later, however after applying my effect, the fx button disappears and it is no longer editable. Anyone experience this? I am completely new to gimp but I saw videos of people doing this no problem with gimp 3.

One of the main reasons I really appreciated and used the former versions of GIMP was the web slice which saved directly to a folder in one simple click. I know you can Slice to Guides but it opens multiple new windows which you then have to save individually. Is there a way to do the web slice direct save process with 3.02? Or is there a script that I can incorporate to recreate the functionality? TIA

Since I moved over to 3.0 I've been having a bit of unnecessary hasssle when copy-pasting selections. When I paste a selection somewhere it still keeps the full image size, just with a big transparent canvas, I assume this is just a setting that I need to turn off. Any help would be appreciated

Edit: I'm asking this specifically because it happens across programs. If I copy a selection or a single Layer of an image and paste it anywhere it comes with the whole canvas in the image size. What might help - If i copy a layer and paste as new image in gimp, the Layer stay intact but the canvas is still the whole size.

Edit2: Solution in the comments

I can't figure this out anymore it's frustrating.

hello guys is there any way to do this in GIMP ? , thanks a lot

I have a selection that I used a set of transformations on. Now the selection is transparent, I don't necessarily need to turn it Opaque but it would be convenient.

I made a little script that takes 3 circular/hexagonal images and aligns them to overlap in a triangle on page to be printed out, created for the express purpose of combining 3 Herocape cards, but that is not really relevant unless you are interested in purpose. I updated GIMP to 3.0 and now my scripts won't work. I tried reading a few tutorials online but don't understand the change but think it has something to do with a change in how you are Receiving an array of drawables. When I run my script I get error: "unbound variable: gimp-image width". See full script here, but below is relevant lines including bolded lines that I think is causing error, any help is appreciated!

just updated to gimp 3 and i have just noticed that, for whatever reason, it seems that zooming now no longer cares about whole round multiples of 50 or 100. i wouldn't really care about there being more steps between zoom levels even though that messes with my muscle memory, but not being able to zoom smoothly into even multiples really messes with my workflow because i mostly edit small images that should ideally be perfect multiples and not have to have any weird uneven scaling applied to them. is there a setting for this?? or what should i do? the + and - keys work like they used to but since gimp zooms to your mouse pointer it's just very awkward and weird and unintuitive.

having a weird issue where Gimp 3.0.2 (or gimp 3.0) wont open after i install (even if i tick open after installation)

i was using an older gimp version and that was working fine, until i decided to update to 3.0.

ive tried completely uninstalling the current program and reinstalling with no luck. i've checked if the Windows AV has blocked anything but it hasnt. i've also tried running as administrator.

can anyone help out? i guess i could try reinstalling an old version but i was looking forward to 3.0 and dont understand what's going wrong.

update: i have installed 2.8 and it works fine, so it's something about 3.0

Hello, I need help! I am trying to export in 3.0, but every time I export in it. It turns a large portion of my image into transparency. I have provided two images 1 which was exported in 3.0 and the other in 2.1 today.

Hi! I'm converting a bad plugin I had for 2.x to 3.x and having trouble with some of the basic methods, as well as parsing the documentation.

In the old plugin, I have a section where I am doing

red_channel = pdb.gimp_image_get_channel_by_name(image, 'Red Channel - Auto')
if red_channel:
    pdb.gimp_image_remove_channel(image, red_channel)
# recreate color channels
red_channel = pdb.gimp_channel_new_from_component(image, 0, "Red Channel - Auto")
pdb.gimp_image_insert_channel(image, red_channel, None, 0)
pdb.gimp_item_set_color_tag(red_channel, 6)

And I think the new version is something similar like

channel = image.get_channel_by_name(channel_name)
if channel:
    image.remove_channel(channel)
channel = Gimp.Channel()
# channel.set_color_tag(Gimp.ColorTag.RED)
channel.set_name(channel_name)
image.insert_channel(channel, 0)

But when I try to set_name or set_color_tag I get an error saying something like

GIMP Error
Calling error for procedure 'gimp-item-set-name':
Procedure 'gimp-item-set-name' has been called with value '<not transformable to string>' for argument 'item' (#1, type GimpItem). This value is out of range.

I've been looking at these pages, and I'm not sure what I'm doing incorrectly.

• https://developer.gimp.org/api/3.0/libgimp/method.Item.set_name.html
• https://developer.gimp.org/api/3.0/libgimp/method.Item.set_color_tag.html
• https://developer.gimp.org/api/3.0/libgimp/enum.ColorTag.html

I've also tried to look for examples but the example plugin is laughably simple. I did see some potentially useful plugins here https://gitlab.gnome.org/GNOME/gimp/-/tree/master/plug-ins/python but I didn't see anything that answered my question, but I'm still searching.

Has anyone encountered anything similar? What should I be doing differently?

e: For doc, I think I should be looking at here instead, maybe? https://lazka.github.io/pgi-docs/#Gimp-3.0

In Gimp 2.10 and earlier, I could just bring up the crop tool then if I wanted (and I often wanted), manually specify the size of the crop marquee by editing the width and height values in the Size field.

In Gimp 3.0.2 it’s just plain weird. Those size values no longer act like normal text-input fields. You can’t double click or click and drag to select the whole value then type what you want for a new value. Instead, all sorts of weird things happen. The image zooms in or out, or gets cleared to all white.

It’s possible to work around the glitch by using the backspace or delete key to delete the old value.

In the chance that this was a deliberate feature, please undo it ASAP! I don’t care how special you think Gimp is, it is not special enough to merit its own special text input fields, with its own special rules. It’s just not. No application is. Graphical user interfaces work best with a relatively few kinds of standard widgets with standard, predictable behaviour across applications.

It just started. I am new to GIMP and out of nowhere all the transparent layers are not transparent anymore because all the layers bellow it get hidden. Can someone help me? I looked around and found out that I am not the only one with this problem but I can't find a solution.

Not only that but I cannot paint on new layers.

I hope I described it well. It's alright if it turns out more like a circle if that's the only way to do it. I can't quite get it to work. If it's not entirely clear I'll try to clear up the best I can

Hello,

Trying to get a circle in mm/cm but the pencil is stuck in px.

I've tried to do these but they didn't work:

1. image properties > resolution > use resolution to calc the number of pixels for 52mm circle

2. preferences > default image > image size to mm > new image > used new resolution to calc the num of pixels/mm

3. changed the ruler units

4. grid units

Hi there

For print on demand via Amazon I would like to use a neon orange, but it doesn't with expected glow effect.

What do I need to check/use to get such an orange? Could be similar like construction warn orange.

Best regards

new gimp is POS. no paste into selection. it was forced on me. I have ubuntu 24.04. I let it upgrade, wish i hadnt. well, how do I get old gimp? a stab;le version? say I dl alreadu 2.8.12, unpacked it, but cant get the terminal to find it. i put it on desktop. how do I install it? i tried sudo apt install gimp-2.8.12. It sez can't find package. Also, new ubuntu has NO app center, I cant get that back either. I am new to linux. going nhutsa

I use GIMP to take normal maps and reformat them to work in sims 4, a process that requires decomposing a normal map, copying the red channel to the alpha channel, and then copying the green channel to the red and blue channels. When I did this in gimp 2.0, I copied the active layer (red) and then pasted it into the alpha channel. It would appear as a floating material and then I would anchor it down. Once I'd done this for each layer, I would recompose the image and it would work.

However when I tried to do this same process in 3.0, when I copy one layer and try to paste it, rather than appearing as a floating material, it pastes as "layer copy" instead as a floating material. If I merge this down, when I go to recompose the image it tells me it can't because "Specified Layer #1 ID 49 Not Found". Why is this happening?

Is there a plugin that can do this in GIMP? If not, can G'MIC do this?
