Designed with Gimp of course, with an interesting technique to generate the adequate polka dots. Might make a quick tutorial about this.

  Colors Exchange effect is permanent, not 1 time-only
Posted by: ldd2 - Yesterday, 07:25 PM - Forum: General questions - Replies (1)

Greetings buddies.

For a long time, I used GIMP v2.10.2 as it was fitting needed requirements for some pixel art files.

I recently have installed most updated GIMP version and got an issue with Color tab > map > Colors exchange

Issue is, in older GIMP version, i used this feature to exchange a couple of pixels with another color from same Color map file (256 indexes only). 

In most updated version, I use same feature and e.g: I switch color index 175 with index 230, all pixels with that color get an exchange. 
The issue here is that this effect is Permanent, and I dont know how to stop that from happening.
In older GIMP version, this effect was just 1 time for this colors exchange. In newer version, if involved Pixels get colors exchange effect, then if I try to use e.g: Index 175, it will paint any next pixel with Color that I used for Color exchange. e.g: index 230, besides i'm selecting index 175.

Thanks, in case can bring help.

  Problem with exporting from GIMP 5.2.0 to TIFF
Posted by: ExAdobeUser - 06-30-2026, 01:21 AM - Forum: General questions - Replies (3)

Hi,

Sorry in advance for the length of this post. TLDR version is that exporting an image from GIMP to TIFF format yields weird results.

All of the work described below is taking place on a Dell laptop with Intel x64 processor running 64-bit Windows 10, darktable 5.2.0, and GIMP 3.2.4. My overall goal is to create a composite TIFF image comprising four cropped photos side by side, and then make a print.

I have four cropped photos that were post-edited from camera raw using darktable and exported to TIFF files using darktable settings shown in the attachment darktable_export_settings.jpg. I checked the darktable exports using Windows photo viewer, and they all looked fine.

I next imported the four photos into GIMP, converting the color profile to the built-in GIMP sRGB. I created an appropriately sized empty image and pasted the photos into it, each on a separate layer, and set the X offsets to arrange the photos. Lastly, I put a white background layer on the bottom to show white separator regions. All layers were set to 100% opacity. The attachment GIMP_preview_scrape.jpg shows the contents of the workspace image preview after all of the editing. The preview looks exactly as I intended.

I then exported from GIMP to a new TIFF file using File->Export As... with the settings shown in attachment GIMP_export_settings.jpg. I think the important thing to note is that I exported uncompressed and did not save layers. This is where the problem shows up. I opened the new TIFF file with Windows photo viewer, and it was extremely grainy (see attachment GIMP_export_preview.jpg).

I tried repeating the entire process but exporting from GIMP to JPG, and the final image was flawless. Obviously I could resort to using JPG instead of TIFF to make my print, but I really want to understand where I went wrong in this process.

Any suggestions?

Thanks,

Mike

  How to iterate pixels with python API?
Posted by: Scallact - 06-29-2026, 12:17 PM - Forum: Scripting questions - Replies (1)

Hi,

[GIMP 3.2 python API]

I'm trying to iterate over all the coordinates of an image, and create some calculated pixel values on a new layer.

I'm currently using the Gimp.Drawable.set_pixel() method, but its very slow (and supposed to be).

I'm struggling to find the right way to do this. I think there was a concept called "regions" in GIMP 2.xx. I understand I have to use a Gegl.Buffer. But from there I'm stuck
I can't find any definition, or just circular definitions, of what a Gegl buffer is, or any other concept. That's what makes things really difficult. 

Does a "buffer" represent the whole drawable? And if it is, how do I extract just a tile and iterate over the pixels?

What is a "shadow buffer"?

What is a "handler"?

What is "the abyss"?

Thanks!

  What's the Best Way to Change SVG Color Online Without Losing Quality?
Posted by: Freecolortheory - 06-29-2026, 07:25 AM - Forum: Other graphics software - Replies (1)

Hi everyone,
I often work with SVG icons and logos, and I'm looking for an easy way to change SVG color online without manually editing the SVG code.
My ideal workflow would allow me to:

  • Upload an SVG file
  • Change one or multiple colors
  • Preview the result instantly
  • Keep the original vector quality
  • Download the updated SVG without losing transparency
I know GIMP can edit SVG files after importing them, but I'm curious if anyone uses an online tool for quick color changes before bringing the file into GIMP or another design application.
What do you recommend? Do you prefer editing SVGs directly in GIMP, or do you use an online SVG color editor for faster results?
I'd appreciate any tips, tools, or workflows that have worked well for you.
Thanks in advance!

  Gimp 3.2.4 tool options dialog

I can't get the tool options dialog to stay. As soon as I click somewhere else on the screen it disappears and I have to load it again. Blush

  Linux LMDE changing default save location
Posted by: Green Pig - 06-27-2026, 10:57 AM - Forum: General questions - Replies (2)

Hello folks,

Long time user of GIMP although still fairly limited experience wise, one thing I keep meaning to look at is how to change the default 'save' location for new xcf files.

Ai summary and YouTube suggest the 'bookmarks' option but on my OS (Linux LMDE 7) there doesn't seem to be that option, just the regular home, documents and so on.

My folder structure is now getting fairly complex so would be a great help and time saver to skip a few selections each time.

Edit: just to add, I do have the 'bookmarks' option on file explorer to it is there just not in the smaller GIMP save window.

Thanks
