Gimp V3 introduces "non destructive editing" (aka NDE).


When you apply filters to layers, instead of altering the layer pixels immediately  (as done in V2), the filter can be added to  a stack of filters which is applied on the fly when Gimp uses the layer contents. When this is the case there is a "fx" icon next to the layer, and if you click on it you get the stack of current filters, that you can further edit. 

   

   

I've been working with Gimp 2.10 for a long time. I'm not a Gimp expert at all just like playing around.
Anyway, I installed Gimp 3-R2 and was trying to do a simple
transparency layer -> Filters -> Render -> Noise -> Solid Noise.
Then I went to the Select By Color tool and it won't select anything.

I tried these exact steps in Gimp 2.10 to be sure and it works fine.

Is there something else that needs to be set up? If there are instructions, I'm happy to read them, I just haven't been able to find anything about it.

Thank you!!

Hi, I'm just tying to understand the details of selecting multiple layers. I get that you can do this with shift or ctrl keys. If for example you wanted to rotate three layers, what's the rule to say which one is used for the "preview" while you are adjusting the rotate?

In gimp 2.10 you could link the layers and choose which one is active so that's the one that's used while you are adjusting the rotate.

Hi all

Just started using gimp again and have an issue I have had in the past but forgot how to fix it.  Applying text to a circle the top of the circle text along path does as intended but when I do the bottom half text it apples to the path like it is stacked and just looks like jumbled up spaghetti. Like I said this has happened before but cannot remember how to fix it. 

The initial text to path requires me to use the flip tool so it looks right but then after the flip I get spaghetti

Hope someone can help 

Cheers

As I saw on the internet, an A4 sheet would be equivalent to a 2480 x 3508 pixel photo in 300dpi. As I need two A4 pages for my project, I created a 2480x7016 image but GIMP (or other software) does not offer me to print on two pages.
So I cut this image in two with a selection rectangle and printed separately. However, the printed result does not match the preview of the image in question (I compared).
Can someone help me? It's incredible that in 2025 we struggle for something so simple...

HELLO I will try to explain my problem. I want to turn an image into a poster with custom dimensions, so I wanted to use GIMP’s guides and crop the image following the guides. The thing I don’t understand is that nothing matches when I put them in the image: the image size, the guides, etc.

I have an image that is 63×83 cm.

I set my margins in cm based on the image scale, but they should be much smaller. Instead, they are still set to 1 cm.

And when I go to Image > Image Size and Dimensions, I get another size entirely.

I am having an issue with the GEGL tool. When I click on any image I get a GEGL Operation dialog. If I click on Cancel the dialog goes away but as soon as I click on the image again the dialog comes back. Even happens on a New blank image. I was using Gimp for a little while before this started happening, and I guess it is possible I did something to cause the problem, but I have no idea what I did or how to fix it. 

SO, I rebooted and then uninstalled/reinstalled Gimp and the problem was still there. Then I uninstalled Gimp, deleted all the GIMP/GIMP 2.10 directories I could find, and reinstalled. Now it is working OKAY. Checked around the forum but didn't see the problem reported anywhere, but does anyone have an idea what is going on ? What could I have done to make this happen, so I don't do it again ?

Thanks, Jack

  and have tried several ways to use it. 
  
  First I saved it in:
  C:\Users\username\AppData\Roaming\GIMP\2.10\scripts\red-rectangle-with-borders.scm
  I tried filters -> Script-FU -> Refresh Script and clicked on filters -> Script-FU and the file wasn't there.  I closed Gimp and reopened it. 
  Then I I looked in help -> Plug-in browser and couldn't find it there. 
  I looked in all of the menus since I read that the scm file could be anywhere but no luck.
  
  So I saved it in downloads and  moved it to this path: 
C:\Program Files\GIMP 2\share\gimp\2.0\scripts\red-rectangle-with-borders.scm  
 I did the same things that I did when I saved it in the roaming folder and still no luck.

Would someone be gracious enough to show me what I did wrong?  Thanks

Yesterday I wanted to change the subject a bit and I fished out an old script of mine to convert the CBR (rar) and CBZ (zip) Comics Books files to PDF on bash using Linux.

I could probably add the CBT (tar) and CB7 (7zip) formats, but I can't find sample files for the tests.
