  GIMP3 Tools ofn3-export-layers Error: car: argument 1 must be: pair
Posted by: smgolden - 06-02-2025, 05:23 PM - Forum: Extending the GIMP - Replies (2)

Using GIMP3 Tools ofn3-export-layers 
https://sourceforge.net/projects/gimp3-t...s/general/

I get "Error: car: argument 1 must be: pair"

GIMP 3.0.4
ofn3-export-layers.zip  2025-04-04  39.8 kB
Windows 11 64bit


Started GIMP.
Loaded image having 45 frames.

File>Export>Export Layers... (Dialog popup)

Provided Output Directory
Frame rate (ms)" 100

Default all other fields:
Filename format: %n_%68.png
Walk Direction: Bottom to top
Count offset: 0
Filter: All layers
Resample mode: Off
Interpolation threshold (ms): 0

Click OK
Get: "Error: car: argument 1 must be: pair"

The script seems to execute because the "Filters" menu drop down indicates it executed.

I don't have a clue how to address the "Error: car: argument 1 must be: pair"

Any suggestions?

  mono mixer bug ?
Posted by: denzjos - 06-02-2025, 11:20 AM - Forum: General questions - Replies (9)

Gimp 3.0.4: Monomixer converts the colors of a photo directly to gray. I tested it with a simple orange layer and this was the result after activating the 'Monomixer' (Colors / Desaturate / Monomixer). A bug ? Using the 'Colour Picker Tool' on the gray layer give orange as result.

  How to rotate text I types
Posted by: snowforest - 06-02-2025, 07:04 AM - Forum: General questions - Replies (1)

I typed a text and that layer is selected. I am doing transform Tools>Rotate but it keeps rotating the whole image which is very counterintuitive. How to rotate just the text I typed?

Question How can I stop the tool from switching when I switch between my drawing pad and mouse
Posted by: RawrTheDinosawr - 06-02-2025, 05:25 AM - Forum: General questions - Replies (2)

Updated to Gimp 4.0 as I switched OS from Windows 10 to 11, and I noticed that now, my mouse and my drawing pad have two separate tools linked to them, which is awkward for me as I use my mouse a lot for panning, zooming, etc. Trying to edit the tool used by my drawing pad is also awkward, as I can't do it with my mouse as it switches to the tool my mouse is using. Switching tools is also inconvenient as I normally do it after adjusting my view, but because I do that with my mouse it switches the tool on my mouse, and then when I go back to using my drawing pad, it's the tool I wanted to switch off of. How can I turn this off?

Showing the switching behavior I'm talking about would obviously be best with a video but I'm currently unable to do that, so here's an image of the two tools that are being switched between.

  Cannot make background transparent
Posted by: RealGomer - 06-01-2025, 05:52 PM - Forum: General questions - Replies (3)

I've gone to several site to try to see how to remove the background of an image. I they all say what I found on fotor.
https://www.fotor.com/blog/how-to-make-b...t-in-gimp/
The attached pix is from a png image. (Hopefully I got it attachedl) I just want the cat to be copied into a document. If you click on the pic, you can see the entire image is shown, not the cat only. Am I missing something? Huh
FYI - I'm trying to create a book for our 4 year old grand son using his buddy at our house.

  color/brightness changes don't transform
Posted by: Timp - 06-01-2025, 05:19 PM - Forum: OSX - Replies (1)

Hi,
I apologize if this has been addressed elsewhere, but I couldn't find it.

I am using Gimp 3.0.4.  I have an image open and select part of it.  I then change the brightness (or color--same issue with both).  Next, I try to rotate the image. However,
The brightness change doesn't follow the image.  Instead, only part of the image has the brightness change.  It's as though the brightness change remained in place while the (now old) image rotated. 

I'd appreciate any advice.

  Stable-Boy Plugin does not appear in top menu
Posted by: Sven - 05-31-2025, 07:40 PM - Forum: Extending the GIMP - Replies (1)

After installing stable boy, stable-diffusion-webui and adding the directory from stable boy the plugin folder into the plugin preference list, stable boy does not appear in the top menu. stable-diffusion-webui does start in my browser and runs.
gimp 3.04. OSX 15.5. stable boy, stable-diffusion-webui from the current github versions. All installed to instructions of their website OK.

Anyone who installed stable boy? or Ideas?

Thanx in advance
Sven

Photo .ora export
Posted by: TheRambler - 05-31-2025, 04:20 PM - Forum: General questions - Replies (4)

Hi


I have gimp 3.04 on windows 11 x64.

Everything worked well with Gimp 2.0 etc.

I use Gimp to create texts and images into .png files these files are then put into an authoring software.

What I generally did is that I exported the different layers into an .ora file that was then changed into a zip file
and I had my layers with my transparency and my text for the menu, film, bonus, and so on.

now I don't have any transparency I just have the cropped images with nothing in it, no text.

Does anybody know how to solve this issue ?
And another problem how can you create an 1920x1080 image with transparency background,
everything has changed I'm kind of lost...It always makes an image with the background color.


Best

  Divide large image into 16 equally sized rectangles
Posted by: mark-in-the-tropics - 05-30-2025, 11:28 PM - Forum: General questions - Replies (2)

Hi everybody Smile
I have a very large Mercator projection which I want to divide into several sections, each of which I will then re-shape to fit the map onto onto a globe of the Earth.
It's easy enough to shrink my image down to say 4096 pixels width, which (in principle) allows the image to be evenly divided into 16 rectangular sections of 256 pixels width. I'm having trouble making the selections. 
The first selection is easy enough, because I have the edge of the image to refer to. The next selection is problematic, because I can't see where my first selection left off. (Hmm, I could have bucket-filled the first selection with black, I guess...)
I can't see how to tell gimp, using numbers, that I want a particular part of the image to be selected out, but I'm sure there must be a way.
Thanks
Mark

Lightbulb [RFC] Summer of code project to re-think plug-in/filter development resources
Posted by: martymichal - 05-30-2025, 02:34 PM - Forum: Gimp 2.99 & Gimp 3.0 - Replies (16)

Hi friends!

My name is Ondřej and I'm one of the 3 students working this year on GIMP as part of Google Summer of Code (see https://www.gimp.org/news/2025/05/18/gim...ased/#gsoc). My project is to help redesign tools in GIMP for helping creating plugins and filters for GIMP. These tools are namely the 'Procedure Browser' and 'Plug-in Browser' that you can find under the 'Help' menu tab.

I would like to learn about your experiences how you develop plug-ins and filters, what resources you use while developing and how these tools help you to get your work done.

What is it that currently works well, that could be done in a better and what is missing at the moment? I would especially appreciate getting to know about your experiences with developing for GIMP 3.

There are many ways in which I could drive this project and having more perspective coming into it is very important to me.

## Ideas

> This is a rough description of what I have written already in the upstream tracking issue (see https://gitlab.gnome.org/Teams/GIMP/Desi...issues/259). For more details, check it out!

The original idea for this project is to create a new browser for exploring the available GEGL operations and how they can be used. In general, having access to this information is important because GEGL operations are the bread and butter of GIMP 3 through the use of the new Filter API accompanying the new non-destructive editing capabilities of GIMP. With that said, there are already ways to get this information: the GEGL website (see https://gegl.org) and the 'gegl' command line (see https://developer.gimp.org/resource/writ...mmand-line). But neither of these is integrated in GIMP nor shows operations registered at runtime.

Another idea is to explore combining the existing two browsers. Instead of having multiple places, where to look for information about available procedures and actions, there could be a single point of reference with all of the information included. This will require some care as to how the information is presented and how does the updated dialog integrate with tools like the Script-Fu or Python Console.

If you have any more ideas, I would love to hear them!

## Following the work

I'm tracking this effort in issue #259 (see https://gitlab.gnome.org/Teams/GIMP/Desi...issues/259) on the GIMP-UX tracker and I'm usually present in the #gimp IRC chat room on GIMPnet. Please, do reach out to me, if you wish to discuss this project or anything GIMP-related!
