After the latest update to gimp, I need an updated libgegl-0.4-0.

If I do:
apt list --upgradable I get:
libgegl-0.4-0
libheif-dev
libheif1

If I then do:
sudo apt upgrade I get:
that the three packages have been kept back:
3 not to upgrade.

How do I solve this problem?
All help gratefully received.

Edit: I should have added that this is the pandajim 2.10.30 with python 2.7 support (thanks to Rich) - everything working until the update today.

For the script-fu oriented, there are now "lambda" icons for the  post/thread header, as a well as a lambda "smiley"(*): 

(*) more like a smirk, IMHO

I just made the switch to Linux and I'm using POP OS with GIMP 2.10.

My cursors are normal sized when using the OS. But, when I open GIMP, the cursor size is massive.
Is there a way to change the cursor size to match the OS cursor size?
I searched through the menus and couldn't see any way to do it.
I tried a couple of things I thought might do it, but had no luck.
Gimp is almost unusable with the super-large cursors.

Thank you for any assistance.

This may be common knowledge, but im new to it.  I need to create a grid for a template i need to print.  Im having issues putting the guidelines exactly where i need them.  Is there a way to specify in inches on where i need the lines? I have discord or whatever just to get help it would be greatly appriciated.

Long read, but hands-on experiments and really worth it anyway: https://ciechanow.ski/gps/

I am trying to draw/paint with only 4 gray shades on top of a black background. I am then exporting the drawing to a file that is read into Python with the PIL library (for image processing) as an image mask. When the file created in GIMP is read into Python, a quick look at the values associated with the palette indicates about 20 values. I'm only expecting five values, the background and four gray values, and not sure why this is happening. I think it possibly has to do with pixels that are not one of the shades I'm trying to stick to in the drawing, what I consider noise. I don't have much graphics background, so I may not have the language I need to describe my problem.

My workflow is:
1. Add a new layer over a camera image I'm working with. The new layer has a black background, the HTML notation is 000000. Call it "next".
2. I select the next layer, turn off its visibility to see the camera image with AOIs (Area Of Interest).
3. I use the paths tool to trace the outline of an AOI on next layer. I modify the paths to fit the AOI best I can.
4. I stroke the path to finish that AOI. I use a white color to stroke the paths.
5. I repeat 3 and 4. I have 4 AOIs in each camera image I'm working with.
6. I pick one of HTML notation colors 030303, 070707, 0b0b0b, or 0e0e0e as bucket fill for inside of each AOI.
7. I change the zoom to 200 or 400% to get a good look at the white outline of each AOI. I pick the respective gray per AOI and color over the white outline to make the whole AOI just one shade and get rid of white.
8. I change the mode of the layer to Grayscale in the Image menu.
9. In Layer>Transparency> Remove Alpha Channel
10. I export to PNG and save as 8bpc Gray with no background color.

I import the PNG to Python and then find that there are 16-20 values in the image.

I've attached an example of one of the next images. It's hard to see one of the AOIs because the 030303 is hard to tell from 000000, but you can see that AOIs get darker from one end to the other.

Is there a way to make sure that I'm just getting the background and the four AOI shades in the PNG?

Hi,
I keep getting the same error message.
How do I either disable or deal with it, please?
It's driving me mad :-)

Excessive number of Xmp.photoshop.DocumentAncestors tags found: 1001. Only keeping the first 1000 values.

Thanks,
Owen

Hello! I've recently started scripting with gimp and I've ran into a problem with posterize. I believe the issue is with how I am trying to implement the blending option. Does anyone have experience with automating the posturize tool with a blending option enabled?

I've found:
gimp_edit_blend()
gimp_context_set_paint_mode()
gimp_layer_set_mode()

Removed Alpha layer, manually using the posterize tool with 2 levels an color erase blending

With my tool set to 2 levels using gimp_edit_blend

A friend of mine, who is into web development, optimises the images by making them small, say 13 -20 KB. He uses Photopea to get his favourite image size at 2000 x 1309 px and exports it into webp format.

I am amazed that he manages to convert even full HD images in the 15 - 25 KB range. Wondering if we can do that same in GIMP. And apply it a number of images. Thanks.

PS: I do have BIMP installed. But not sure how to use properly for this use case.
