  Resize multiple PDF pages from A4 to A3.
Posted by: pascal079 - 09-11-2026, 05:46 PM - Forum: General questions - No Replies

Hello, 
I am French and am posting this with the help of a translator. I use GIMP 3.2 on Linux Mint. I have a multi-page PDF in A4 landscape format, and I would like to resize all the pages to A3, also in landscape format. Is this possible, and if so, how? 
Thanks.

Merci

  is there a crop tool setting I can change in 3.2.4?
Posted by: John A. - 09-10-2026, 11:32 PM - Forum: General questions - Replies (2)

Hi,

I've just changed from 2.10 to 3.2.4 and I'm having a few hiccups. The one for today is the crop selection tool. In 2.10, I couldn't select anything beyond the canvas, which suited me just fine and made it seem faster to crop thousands of screenshots. I often have to zoom in to 800% for precision. Now with 3.2, the crop tool can extend beyond the canvas so when I zoom to 800% at the edge, the crop selection handles aren't visible without jumping through hoops. 

Is there a tool setting I can change to restore the behavior preference?

The screenshot is just intended to show what I mean by "the crop selection tool extends beyond the canvas" in case that needed to be shown.

Thanks much,
John A.

Tongue 3.0 Batch Image Watermark Plugin [No resizing]
Posted by: bluedrop2007 - 09-10-2026, 07:59 PM - Forum: Extending the GIMP - Replies (1)

After being asked to put my name all over some pictures, I definitely knew I *was gonna use a GIMP automation*, therefore I spent all afternoon searching for a batch watermark plugin working for my version of GIMP, long story short, I found this plugin in another forum and I ran with it. To install it just make sure you know where your current GIMP Version Config is stored in (by that I mean I.e C:\Users\foobar\AppData\Roaming\GIMP\3.2,where you can find a folder named plug-ins or a file named pluginrc), now you should have a structure like this:
...\GIMP\3.2
> plug-ins
   >Watermark3_from_Image_OWN
      >Watermark3_from_Image_OWN.py
pluginrc (Basically you delete this file to refresh the plugin list)
And after restarting GIMP you get a new option under the "Edit" menu.
  
PRO TIP: You can drag and drop the watermark file from your file manager(in windows AFAIK) to the watermark file input.
  
The main changes are that the original version lacked center alignment, and it wasn't adapted for batch watermarks. This version lacks resizing tho! So make sure your watermark image is the right size, or make your own patch, this has a lot of potential, plus it "just works" on GIMP 3.0.
It supports a lot of image containers however I only tested PNG,JPEG and JPG and honestly it doesn't feel slow but It could be faster *sigh*.
 
IMPORTANT NOTICE:After force stopping the plugin and closing GIMP, a bug tracker notice might pop up
P.S: Thanks for all the people active in these GIMP forums, you all genuinely keeping it alive and it's honestly interesting to read most threads. Specially oFnuts and all the people who submit bug reports or propose features or ask questions (like how to have python plugins located in submenus and or different menus)

  How to turn off Lighting Effects? My god.
Posted by: Tom Atkinson - 09-10-2026, 04:03 AM - Forum: General questions - Replies (5)

My god.  What an intensely frustrating experience, trying to turn off the lighting effects.

I am a bit of a newbie and had been experimenting, and got to the point where I now just wanted to turn them off completely, so as to get back to where I was before I started the experimenting.

I was unable to turn them off!!  I tried every kind of reset (reset all filters, reset to initial values, reset to factory defaults, etc), but none worked.  Trying to manually change the lighting effects so that they had no effect also did not work!

In the end, I did CTRL-Z many many times to get back to an appearance I was prepared to live with.

How on earth do you turn them off?  Every attempt to manually neutralise them just made things worse!

Surely there is an easy way to turn them off!  What a frustrating experience.  HOW DO YOU TURN THEM OFF?

Gimp 3.2 on Windows 11 Home.

Thanks.

  How to use script-fu for loading images stored in files?
Posted by: aKe6/Bg - 09-03-2026, 02:22 PM - Forum: Scripting questions - Replies (2)

I am trying to manipulate images stored in files.
As a first exercise, I tried to open an image, and then save it to a file 
with another name. Note both the source and the destination files already 
exist in the file system before my manipulation. I do not mind overwriting 
the contents of the destination file.
The code I have tried is:

Code:
(script-fu-register
   "copy"             ;func name
   "copy"             ;func label
   "Copy a file containing an image to another file. Both file exist in the file system. The destination file will be overwritten."                ;description
   ""                 ;author
   ""                 ;copyright notice
   ""                 ;date created
   ""                 ;image type that the script works on
   SF-FILENAME    "Input file"     ""
   SF-FILENAME    "Output file"    ""
)
(script-fu-menu-register "copy" "<Image>/Image/Transform/")

(define (copy inImgFile outImgFile)
   (let* (
              (image (car (gimp-file-load
                           RUN-INTERACTIVE
                           inImgFile
                          )
                     )
              )
             (gimp-file-save
               RUN-INTERACTIVE
               image
               outImgFile
               %NULL
              )
         )  
   )
)
When running this code, I am prompted to choose the input and output files. There also seems to be a brief
message at the bottom of the screen about one of gimp-file-load or gimp-file-save. Other then that, nothing
happens. In particular, nothing seems to change for the output file.
If I run gimp from the terminal, and quit gimp after running this script-fu I get (in the terminal)
Message in the terminal Wrote:INFO: a stray image seems to have been left around by a plug-in: "[name of the input file, without extension] (imported)"
What am I doing wrong?

  Separation-Luminosity-Couleurs script
Posted by: denzjos - 09-01-2026, 04:32 PM - Forum: Extending the GIMP - No Replies

Separation-Luminosity-Couleurs.scm is a simple script that creates a layer group named 'Couleurs/Luminosite Separation', consisting of a 'Color' layer and a 'Luminosity' layer. You can use GIMP's 'Curves' or 'Levels' tools (or other filters) to easy adjust the color or brightness of either layer. It is a simple script, but someone might find it useful.

  Gimp 3.0 to 3.2 AppImage migration.
Posted by: teapot - 08-30-2026, 07:33 PM - Forum: Linux and other Unixen - Replies (2)

On linux on my main system installed gimp (so not an appImage) I can do a fresh gimp 2.10 to 3.0.4 migration:

Make sure gimp isn't running.
cd ~/.config/GIMP
Create backups of 2.10 and 3.0 using cp -a if not already done.
Make sure the 2.10 directory is present.
rm -rf 3.0
Open gimp

For later versions of gimp I have each AppImage setup in a separate directory e.g.  for 3.2.4 I have a directory that contains the executable GIMP-3.2.4-aarch64.AppImage and it's matching GIMP-3.2.4-aarch64.AppImage.config and GIMP-3.2.4-aarch64.AppImage.home.  When running this gimp detects the correct matching config and home directories.

However I can't get the 3.2.4 AppImage to pick up a migration from 3.0.4. I tried:

Make sure gimp isn't running.
cd GIMP-3.2.4-aarch64.AppImage.config/GIMP
rm -rf 3.2
cp -a in a 3.0 config directory from an older AppImage
Open gimp
There's no sign of a migration.

Is it possible to migrate between 3.0 and 3.2 AppImages and if so how?

  Should I reinstall
Posted by: Grimpo - 08-28-2026, 09:44 AM - Forum: General questions - Replies (6)

I've got 3.2.4 on a new comp, but I'm finding that GIMP is not playing well since I installed it. All sorts of funny things are happening. Sometimes the Healing tool behaves like a Clone tool, sometimes drawing processes crawl along at a snail's pace, you can see it creeping along, sometimes the file type for exporting is different than the regualr type even though I'm exporting the same type of image, etc etc.

Before I go to all the trouble of giving the comp some diagnostic surgery, I'm wondering, will it help to uninstall and reinstall GIMP? Or is that pointless?

Thanks.
