  file-glob always returns an empty list
Posted by: pyjamaslug - 08-09-2025, 10:31 PM - Forum: Scripting questions - Replies (6)

Hi, I just set out to write a tinyscheme script that retrieves the list of files from a folder using file-glob and although it looks trivial I can't get it to work. 

the line in question is:

(let* (filepaths (cadr (file-glob (string-append input-path "*.png") 0))))

which always returns empty whether I place it in a script or type a version into the console. Gimp just tells me that parameter 1 to cdr needs to be a pair.
Yes, I have verified that the folder pointed to by input-path exists and that there is at least one png file in it.Permissions are ok (I can load the file explicitly)
I have tried unix style and windows style path separator: nothing works.

I can hardly believe something this fundamental is actually broken - is there something about my setup that is wrong? I have a standard 3.04 installation using the windows installer any insights are appreciated.

  moving completed file to new project
Posted by: skunkworks - 08-09-2025, 06:48 PM - Forum: General questions - Replies (2)

Using a paperback cover template, I created and exported the final PDF file. I need to create a paperback cover using a different template provided by the distributor (PNG). Is there a way to port the work already done into this new template and "massage" it?

  Gimp 3.0.4 python batch interpreter oddities
Posted by: Andrew_L - 08-09-2025, 11:47 AM - Forum: Scripting questions - Replies (5)

Hi,

I use the python-fu-eval batch interpreter on GIMP 3.0.4 AppImage and have noticed some unexpected behaviour. As a trivial example,


User:~$ ~/AppImages/gimp/GIMP-3.0.4-x86_64.AppImage -i --quit --batch-interpreter=python-fu-eval -b 'if True: a="something"; print(a);'
something
batch command executed successfully


But if the "if" statement comes after the declaration of variable "a"

User:~$ ~/AppImages/gimp/GIMP-3.0.4-x86_64.AppImage -i --quit --batch-interpreter=python-fu-eval -b 'a="something";if True: print(a);'
batch command experienced a calling error:
Traceback (most recent call last):
  File "/tmp/.mount_GIMP-3bPBAmP/usr/lib/x86_64-linux-gnu/gimp/3.0/plug-ins/python-eval/python-eval.py", line 42, in code_eval
    exec(code, globals())
  File "<string>", line 1
    a="something";if True: print(a);
                             ^^
SyntaxError: invalid syntax

Similar problems arise with a "with" statement.

I don't understand this. Has anyone else noticed this sort of behaviour?

My OS is linux 6.1.0-37-amd64

Thanks.

  Python, something completely different...
Posted by: denzjos - 08-09-2025, 09:29 AM - Forum: Watercooler - Replies (4)

The British Post Office is releasing a special series of 10 stamps honoring the British comedy collective Monty Python. Nice! Four of the stamps depict scenes from the film "Monty Python and the Holy Grail," which was released exactly 50 years ago this year. The remaining six stamps feature the members of Monty Python: Graham Chapman, John Cleese, Terry Gilliam, Eric Idle, Terry Jones, and Michael Palin.
When I'm walking through Bruges, Belgium, and hear a horse-drawn carriage approaching, I always think of the scene with the coconut. I'll say to my wife, coconut sound, John Cleese's coming. I've never heard a reaction from the tourists around me... Monty Python humor, a little different ?

  Can I use the move tool to move the image without moving the layer?
Posted by: blogsofwardotme - 08-07-2025, 10:35 PM - Forum: General questions - Replies (4)

Hi there, I regularly update Gimp now 3.0.4, but it still drives me crazy the image moving all over the place when I pull a selection string or just scrolling the image around with my trackpad.  Do mac user find it more stable downloaded from macports? in the meantime I tried to use the move tool to move the image but it moves the layer too. Thank you

  Creating a Flyer in GIMP with a Multi URL QR Code
Posted by: GibsontheIbsen - 08-06-2025, 04:05 PM - Forum: Extending the GIMP - Replies (2)

I wanted to design a flyer in GIMP that includes a multi URL QR code, wich is basically one code that sends people to a page with multiple links (my website, social media and a contact form). I didn’t feel like installing any Python plugins or messing with the GIMP plug-in folder, so I kept it simple and did everything outside GIMP, then imported the result.


What I did:

  1. I used a QR generator that supports multiple links. Most modern services allow you to create a multi URL QR code using a dynamic landing page inside their service. I added all my links and customized the page with my logo and colors.
  2. I exported the QR code as a PNG. The site lets you download in high resolution, and even vector formats if needed. PNG worked fine for my case.
  3. I opened my flyer project in GIMP and imported the QR code.
    I used File > Open as Layers to bring in the QR PNG, then scaled it down while keeping interpolation set to None to preserve sharp edges (blurry codes leads to huge scan fails).
  4. I added a small label below it “Scan for links” to make it obvious.
  5. Tested the scan at actual print size using my phone camera. Worked right away.

  Faster PCIe 8.0 slot: The future.

I have PCIe 3 slots on my computer (I used CPUID CPU-Z to find the version). The PC works fine. New PCs may have PCIe 5 slots and in the near future PCIe 6 slots. Currently, one is developing a PCIe version 8:

  Color function "equalize" is different to earlier versions
Posted by: Merlin - 08-05-2025, 06:25 PM - Forum: Gimp 2.99 & Gimp 3.0 - Replies (2)

I have been using the “equalize” function to correct images with poor color matching. 
Menu: Colors - Automatic - Equalize
Python: t = layer.equalize(False)
This worked well in Gimp version 2.10.38. In Gimp version 3.0.4, the result is different. Based on the histograms, I suspect that this is due to the processing of the images in the linear color space. Unfortunately, the results of version 3.0.4 are significantly worse (too bright), regardless of the format of the source images (integer, float, linear, non-linear). 
How can I get the results of the earlier versions back in version 3.0.4?

  Editing the Open File dialogue's recent list
Posted by: Michkov - 08-05-2025, 01:45 AM - Forum: General questions - Replies (1)

Hello everyone. I'm trying to customize the UI of my GIMP installation and would like to remove all the default items, i.e. everything in the yellow box in the attached image, from dialogue.
[img]     [/img]
I tried right clicking them, but the removal option is disabled. How would I go about getting rid of them?

Thanks
