  Gimp 3.2 create indexed color image ist different from 2.10
Posted by: bluedxca93 - 10 hours ago - Forum: General questions - Replies (1)

Hi, 
I did try to create a Screen Print draft
Then because of my sloppy File saving as jpg i wanted to reconvert IT to PNG and only as two colors to Print  black one a transparent foil using a normal laser printer. However the indexing mechanism somehow works different on Gimp 2.10 and 3.2. The thresholding Filter also behaves very differently. New Version works better for high res while Gimp 2.10 IS more accurate on Low res. Ist there a reason or an explanation what exactly changed with 3.2?

  I have written a plugin for sending image to Krita. Can I also write a plugin for se
Posted by: zzh - 09-14-2026, 05:53 AM - Forum: Other graphics software - No Replies

Hello! I have written a plugin to send image to krita, and I also want to write a plugin to send images to gimp. Can I make some changes to achieve this? In addition, I have developed software that works with plugins. You can download it by searching for "Data to 3D Pro" on the App Store. This software has many functions and can assist in painting. To download the plugin, you can click on this link: https://github.com/zzh2024424/krita-plugin . You can write your own app or software to use with this plugin. If it is for Android, you need to replace the "com. example. datato3d/. MainActivity" in the "adc_command" of the plugin with your own package name and main function entry. I hope this can be helpful for painting enthusiasts.

  NDE and sampling confusion.
Posted by: teapot - 09-14-2026, 02:29 AM - Forum: General questions - No Replies

Hi,

I'm confused by how tools that sample a layer interact with non destructive editing. An example:

On a new layer filled with white:
Draw three green circles making sure they don't overlap.
Filters -> Distorts -> Ripple un-merged.
Set the foreground colour to red.
With the bucket fill tool click on one of the green shapes.
The layer doesn't fully update right away, that's already got a bug report, so toggle the layer's visibility off and then on to trigger an update.

What happens is the ripple is applied 'twice':
The bucket fill samples the layer including the visible un-merged ripple.
It writes the result of the bucket fill to the layer, this includes the ripple.
The un-merged ripple is still being applied to the layer.
The result is the whole layer is rippled twice even though all we did was bucket fill one of the three shapes.

I tried this in 3.2.4 and 3.2.6.
Is this expected behaviour?
If not what should it do and has it been reported?

  Inverting Grayscale measurement scale
Posted by: Chemtech - 09-13-2026, 01:36 PM - Forum: General questions - Replies (4)

I'm working on making digital negative exposure curves for alternate photo processes.  Tutorials showing new curve creation using a step wedge show the step wedge scanned as 8-bit grayscale and loaded into PS, then the steps are measured using the Info window with white measuring 0% and black 100%.  I'm obviously trying to use GIMP and the grayscale measure tool measures the white step as 100% and the black as 0%.  Is there a way to invert the GIMP measurement scale so the white is measured as 0% and the black as 100%?  Or is Color>Invert the step wedge, and measure that, the only solution?
Thanks.

  Resize multiple PDF pages from A4 to A3.
Posted by: pascal079 - 09-12-2026, 07:28 AM - Forum: General questions - Replies (1)

Hello,

 I am French and am posting this with the help of a translator. I use GIMP 3.2 on Linux Mint. 

I have a multi-page PDF in A4 landscape format, and I would like to resize all the pages to A3, also in landscape format. 

Is this possible, and if so, how? 

Thanks.

  Gimp Background colour.
Posted by: TeckyWalla - 09-11-2026, 06:45 PM - Forum: Installation and usage - Replies (3)

I am suprised at the apparent number of people that select the black working screen for Gimp, going by the youtube videos out there.
Personally if I am goint to draft a drawing by hand, My first thing is to grab a WHITE sheet of paper to sketch it out on using a dark pencil etc..
Which I also tend to use with Gimp.
I wonder if they represent the majority ?? Confused

  is there a crop tool setting I can change in 3.2.4?
Posted by: John A. - 09-10-2026, 11:32 PM - Forum: General questions - Replies (2)

Hi,

I've just changed from 2.10 to 3.2.4 and I'm having a few hiccups. The one for today is the crop selection tool. In 2.10, I couldn't select anything beyond the canvas, which suited me just fine and made it seem faster to crop thousands of screenshots. I often have to zoom in to 800% for precision. Now with 3.2, the crop tool can extend beyond the canvas so when I zoom to 800% at the edge, the crop selection handles aren't visible without jumping through hoops. 

Is there a tool setting I can change to restore the behavior preference?

The screenshot is just intended to show what I mean by "the crop selection tool extends beyond the canvas" in case that needed to be shown.

Thanks much,
John A.
