Hi, I'm a newbie and using GIMP(2.10.36) on Mac for several months. I have a question about Layer Mode: Addition.
According to the official guide, the Addition equation is "The pixel values of the upper and lower layers are added to each other. The resulting image is usually lighter."
So I made my own example to make sure this equation.
As far as I know, the Addition equation would be "E = min((M + I), 255)". According to the equation, "E = min((227.0 + 53.0), 255)" should yield 255. However, I got 232.0 as a result. Why does it happen?
A few weeks ago I updated all the programs on my manjaro Linux laptop, including gimp. Today I used this updated gimp and tried to make some small changes to a PDF file and then to export it again as PDF.
On this latest version of gimp (2.10.36) such an exported PDF file turned out to have 3.7 Mb.
On the previous version of gimp (2.10. 28) the same pdf file with the same adjustments and settings when exported as pdf has only about 475 Kb.
Everyone can probably replicate the same thing if you open a smaller PDF file in gimp 2.10.36 (let's say around 400 Kb) and even without any changes export that same file as PDF. The exported file will be significantly larger than the original. However I presume that this might happen only with PDF files that contain scanned images. I haven't experimented with plain text PDF files.
I wonder why this change was introduced into the latest gimp version which is available for the installation on manjaro (2.10.36)? It doesn't make sense to have a significantly larger file which is not better in any way than the smaller one from previous versions of gimp.
2 years ago I installed Ubuntu 22.04 and was using it at least 3 months before release date in April 22.
Now with 24.04 I'm finding it full of problems a month before release.
24.04 Gimp version is 2.10.36 as a deb pack and maybe it will be the last of the 2.10 series?
Ubuntu's snaps appear in Synaptic package manager (I still use it) along with all the deb packs except you can't use snaps to build anything on because they have their own filesystem.
Ubuntu Pro. Why are some open source apps now part of an elite group of 'cloud computing' apps?
ATM Ubuntu 24.04 looks like it was made by over-zealous script kiddies who have decided to become a management layer in a flat open source world.
Sorry I'm negative about this but in 2024 everything is broken (except France )
because that means i only know how to do the easiest things in the world, of which i can't even do that
let me prove it;
using gimp 2.10.18;
i have a multi-page PDF. and i'm trying to edit a page thats NOT the first page
on the right side - lower column - i see all the pages there!!!!!!!!! (my view is set to the default view) (where the first row of buttons are layers/channels/paths)
when i click on any page thats NOT the first page - nothing happens. i can't see that page in the center section (ya know where you want to make changes). only the first page is in the center section.
this obviously makes me feel like the dumbest person in the world as i can't do the simplest thing
G'MIC just added different map projections to their filters, thus in GIMP you can now make those map gores via the pugin-in G'MIC.
Update your G'MIC filters and a new category will appear Map Projection select Sinuosidal Map, increase the number of Slices as you wish.
Note: To work(or you will get an error in the preview), your image should not have an alpha channel, thus before launching G'MIC ➤ remove the alpha channel from that layer Note2: Discussion is over-there from David Tschumperlé post > https://discuss.pixls.us/t/two-new-filte...n/19890/12
I want to make a watermark on the image with big transparent letters.
Here is what I did:
I opened my image with gimp.
I created a text box. I typed the text of watermark.
Now how can I make this text transparent and rotate it so it becomes like a watermark?
Or tell me please how to do a watermark properly, if I am not on the right track...
I often work through a list of many images in two or three versions that I want to combine. I know I can use Gimp's menu to open images as layers, but I would like to do this from my file manager (here on Linux, dolphin): select the images -> open with -> Gimp as layers
Is this somehow possible to add to the context menu of dolphin? If so, how?
(
To explain:
I have a large list with fileA.png, fileA-v1.png, fileA-v2.png, fileB.png, fileB-v1.png ...
I have this list open in dolphin.
Right now I select e.g. the 3 fileA versions, open with -> Gimp, have 3 windows, copy ...v1 and ...v2 as layers to the original, close v1 and v2, do the work in the now layered image, save that, delete v1 and v2 in dolphin... open the next set...
I do this from dolphin because the files stay selected, I can delete the versions I don't need anymore directly and thus keep track of which images still have to be worked, without the need to remember the last file name. While in Gimp's dialog I cannot delete files, must remember which files come next, and must scroll down in the list to select them.
So it would be nice if I somehow could have a possibility to open dolphin-selected files directly as layers. It would save me the steps of copying and closing windows.

I am trying to use the PhotoLab Curve Batch script in GIMP to apply a curve to a batch of images in a folder. However, I am getting a "RuntimeError: 実行時エラー" error when running the script in certain folders, but it works fine in other folders. Details:
GIMP version: 2.10
Script version: 2.0
Operating system: Windows 10
Error message:
Code:
Traceback (most recent call last):
File "C:\Users\xxx\AppData\Local\Programs\GIMP 2\lib\gimp\2.0\python/gimpfu.py", line 741, in response

pdb.gimp_curves_spline( imglayer, HISTOGRAM_RED, len(icurvered), icurvered )
RuntimeError: 実行時エラー
The script works fine in some folders, but not in others.
The files in the problematic folders are all JPEG images.
I have tried changing the curve file, but the error persists.
Questions:
What could be the cause of this error?
How can I fix this error?
Additional information:
I have attached a sample image from the problematic folder.
I would appreciate any help in resolving this issue. Thank you.
