I've been looking into the GIMP Layers tab's "Composite Space" option, and I'm rather confused by it.  Given a background of white pixels and a foreground of black pixels at 50% opacity, I'd expect the RGB linear colour space to give me sample merged pixels of 128,128,128 because that's about 50% of 255,255,255.  However, with RGB (linear) selected I actually get pixels of 188,188,188 - significantly lighter.

   

When I select RGB (perceptual), though, I actually get the result I'd have expected from the linear model; pixels are darker at 128,128,128 - half way between white and black.

   

Is this a bug with GIMP's options here being the wrong way round, or am I misunderstanding something?

How do you change the default text in version 2.10.38 (revision 1)?

I would like my text to be bold without having to click the Bold button every time I create text.

I wouldn't need to do this but ever since Gimp updated on it's own to this version, my text has been so thin I can hardly read it. It looks like the same font but it looks different than the text that was created using the earlier version.

Hello,

Description of the problem:

I want to use the recipe for "Freaky Details" (https://www.gimp-forum.net/Thread-Look-m...-Gimp-2-10), That is:

 - Make two copies of your original image (three layers total)
 - Color>Invert the top layer
 - Filters>Blur>Selective Gaussian blur the top layer (radius around 5 px, max delta around 0.2)
 - Add a layer group at the top, and move the top two layers in it
 - Set the color-inverted layer to Vivid light mode
 - Set the layer group to Overlay mode

If I do so in Gimp3.0 RC1 everything is OK

Next I change the original image with the function: color -> exposure (+ or - , both tested)
After applying the recipe the result is now unexpected. Sie screen1.jpg.

If I remove the non-destructive filter (exposure) from the top image (the inverted one) everything is OK.
See screen2.jpg.

   

   

Hi,

I would like to modify the hue-chroma of some images.

I tried the following function:

I'm using gimp 2.10 on a Debian 12 system.

My gimp script successfully convert the SVG to PNG, but it doesn't resize it.

Here is my script ~/.config/GIMP/2.10/scripts/convertresize.scm:

Windows 10 64 bit, GIMP 3 RC1 

Hi,

I just installed GIMP 3 RC1. The first thing I did was hook up a pattern folder in the Preferences dialog.
   

When I restarted GIMP 3, I get a slew of repeated errors, one for each file I suppose, listed in the console.
   
Is this an issue? Do I need to report it? Is there a fix?

Thanks for your attention.
Charles

It's now released and I made a test appimage. This is still work in progress for the developers.
Debian-derived systems could try Gimp 3.rc1 from my github.



   

I'm new to Gimp. Is it possible to edit a Photoshop mockup file in Gimp on a Macbook? In Photoshop, I was able to just double click the "Edit Me" section/thumbnail and a new tab would open where I can place my design, but I can't do the same in Gimp. I want to attach a screenshot to give an example, but I couldn't due to the file being too large. Watching videos to help me reduce the screenshot file was no help either.

Hi.
I'm using Gimp 2.10.38 on a Windows 11 PC and I am having trouble printing photos.  I load the photo and edit it but the colour changes I make are not reflected in the printed photo.  I am using a Canon Pixma TS8350 printer and have updated the drivers.
The photo I am trying to print is coming out a little pale and with a slight blue hue.  I used the Curves tool to increase green and red and these changes are shown in the screen image.  When I print the picture the printed image is no different from the original.  I am probably doing something wrong but I can't see what it is.
Thanks.
Chris.

Is there any way to sharpen the faces of all persons on the photo attached.  If YES, please advise the detail steps how to do it.

Thanks in advance
