Hello,
For months now various tools and functions have not been working properly or at all in Gimp. The select by colour often makes a selection, but, for example, I can't invert it and delete or change the background, or the selection itself. Once I've made a selection by colour, I have tried the manual command as well as clicking the option in the EDIT tab to fill with forground colour, but nothing happens. There are other tools and functions not working either. I'm stuck. Can anyone help? I have Gimp GIMP 2.10.32 currently. I use a Mac Monteray. 12.6.1

I see the measure tool defaults to pixels, I don't find a setting to change that to any other unit of measure. Is there such a setting and if so how do I access it?

Thanks.

Hello everyone, Merry Christmas. When i use the g'mic filters they all work great except the dream smoothing filter. when i apply the filter my image turns white?? Any suggestions??

I hoping to find out if it's possible to take an image used for a background and create a curve in it.  The ideas is to create a rotunda-like appearance with the background being the walls and another object being placed central to the rest.  

I could be up in the night on this.  Most definitely it's above my current GIMP abilities.  I don't even know what to search for in tutorials or in this forum to find where to begin.  I did find the warp tool, and it has possibilities I think but it's not working to create the desired effect.  It looks more like a mess as if I was stirring in one paint color into another.  It just got sort of swirled around.  I found my cursor and fingers wouldn't cooperate to result in an even warp.

I'm trying to post at GIMCHAT and I get this error message:

This site can’t be reached

The connection was reset.

I clear my cache and cookies.Can anybody help or have any Idea why?  I'm on Windows 10 .Thank you in advanced.


**Never mind, I found out that is a Chrome issue. I used Firefox and I was able to post.

In Photoshop, there is Snap to Layer option, to snap the cropping to an edge of a layer.

In GIMP, we can use Layer > Crop to Content to crop based on a layer boundary, but there is no option to snap the cropping to an edge of a layer.

Please check the screenshot below and see the layer with a red rectangle in it:

Layer Example

How to snap the cropping to the bottom edge of the layer, since there is no Snap to Layer option?

We can do this easily in Photoshop:

Hello, I'm running Gimp development release 2.99.14 on a surface pro, \w windows 11.
I am having trouble getting the dot for dot mode to match my display's pixels.

My display's resolution is 2880 X 1920 (267 PPI).

My windows display scale is set to the default of 200%.


Gimp detects the ppi as 133. I assume this is correct as it's 1/2 of 267, rounded down to the nearest pixel.

Problem is, in dot for dot mode, Gimp shows the image at 2x -- 500 Gimp pixels are actually 1000 pixels on my display.
If I change Gimp's display settings to 267 pixels/inch, I don't see any effect.

My workaround has been to set the ppi of my image to double the ppi set in gimp and turn off dot for dot.

Does anyone know of a way to get dot for dot mode working properly?
I'm hoping that there is just a setting that I'm missing or confused about.

If not, is there a way to set dot for dot to disabled by default?

Hello,
What is the easiest way to turn a greyscale layer into channel (selection)? So, let's say, blacks will be non-selected, greys will be semi-selected, and whites will remain fully selected?

Learning Scrpt Fu is slow. Any assistance is welcome regarding the Error message.


I am trying to replicated the reported success of others who have posted online. I am running GIMP 2.10.32.

Opening CMD Window within the folder:

C:\Users\parkinsj\Desktop\GIMP_Batch\

; which contains two JPG files, I ran the following:

gimp-2.10 -i -b "(batch-auto-fix "C:\Users\parkinsj\Desktop\GIMP_Batch\img*.jpg")" -b "(gimp-quit 0)"

The result was:

batch command experienced an execution error:
Error: eval: unbounded variable: C:\Users\parkinsj\Desktop\GIMP_Batch\img*.jpg

The SCM file   batch-auto-fix.scm   is at location:

C:\Program Files\GIMP 2\share\gimp\2.0\scripts

The SCM file reads:

(define (batch-auto-fix pattern  
                radius  
                amount  
                threshold)  
  (let* ((filelist (cadr (file-glob pattern 1))))  
   (while (not (null? filelist))  
      (let* ((filename (car filelist))  
          (image (car (gimp-file-load RUN-NONINTERACTIVE  
                        filename filename)))  
          (drawable (car (gimp-image-get-active-layer image))))

Hi all, new here, first post. I'm running W11, and the latest GIMP version: 2.10.31 Rev 1.

I've been using GIMP for probably 10 years just for playing around, nothing really serious. I am completely self-taught, but for occasionally Googling or taking a peek at the manual. I've only learned what I had to learn to keep me going at the moment.

So I DLd the latest GIMP onto my new laptop and it was mostly okay, but I cannot get it arranged the way I used to have it, and the more I mess with it the worse it gets.

What I want is to get the toolbox anchored in the upper left corner, with the selected tool options anchored below it. And a year or so ago, quite by accident, I anchored the text selections in the upper right corner, which makes it much easier to use because it is much bigger.

Docking, Single Window Mode, yadda yadda, I can't figure out what I need and it's getting frustrating. I've been using Windows for 30 years and I know that what I need to do can be accomplished with a few clicks IF YOU KNOW WHAT TO CLICK AND WHAT THE DESCRIPTIONS MEAN. That's the problem.

At any rate, thanks for any help.
