Looking at the two images attached, I would like to change the size of the dockable dialogs in the top row of image 1. Furthermore I would like to change the size of other parts of the interface like the top row in image 2, which starts with 'icons' of "edit this brush" on the left and ends with "open brush as image" on the right. Same goes for the row at the bottom of image 2 or the expand symbol in the second row at the top to the right (image 2), same symbol in the top row of image 1 to the right.  

Background information: I am experiencing an unresolved bug described in this link: https://gitlab.gnome.org/GNOME/gimp/-/issues/5475 which results in an offset when using a pressure stylus on my Wacom Cintiq 16 on a Windows 8.1 operating system. This offset goes away when I change the "size of all items" to smallest in windows display settings. ie. drag the bar all the way to the left. Now I can use the drawing tablet on a 1920x1080 resolution without having an offset on my pen, but the interface in gimp becomes so tiny that I can feel my eyesight deteriorating in real time. 

So I was able to change the size of the icons like brush and eraser easily under "edit-preferences-icon theme" and set icon size to custom.
Then I was able to manually change the font size in the gtkrc file as described here: https://www.gimp-forum.net/Thread-Charac...-text-size

Those two steps make for a much more appealing result already, but now that I'm at it I would also like to manually resize the other parts of the interface to have a full workaround. This would also include things like increasing the size of layers in the layers dialog and what have you, but adjusting what's specified in the images would make me happy.

I suppose my objective can be reached by tweaking the gtkrc file some more, but just randomly increasing values after every "width" and "height" and "size" didn't quite do the trick so I'd much rather ask for the help of a seasoned gimper who might be familiar with the code.

Dear all,

I'm vectorizing images with the help of GIMP. I start with an image like this:

then with the color selection tool I select all the lines:




ad after I export the selection to Qgis, with an apposite tool. The problem is that the selection for each line  is "doubled": one for one side, one for the other. Here a zoom:

 

Well...is there the possibility for GIMP (maybe with a different tool) to select with just a "line selection", right in the center of the original lines?

Thank you

Im not having any functional issues using gimp right now but am curious about what those two black-blue dashed lines near the top of my image are for and how to get rid of them.

Hi and thank you for your help.

I made the attached background many years ago with CorelDraw. It had a function where you give it 2 or more colours, CorelDraw then mixes them up and this is what you get.
Does GIMP have something similar? I need to create another background but with different colours.

Thanks.

Is there a simple way to make the shortcuts like photoshop? If not, I hope the developer make it in the next update.
I also use Inkscape and the shortcut option is really helpful.
Thanks!

Hi,
I have an image formed by a gradient between red and white.
Basically the red saturation is 100% on the left and decreases as it goes to the right.

My question is about the Colors - Hue-Saturation... filter

If I make a selection on this image and apply a saturation adjustment via Colors - Saturation..., the change is visible, whether I increase or decrease the saturation.


However, if the adjustment is done via Colors - Hue Saturation... the change is only visible if I reduce the saturation. If the saturation is increased, even to 100%, nothing is noticeable.


Is it a bug or is this filter behaving as it should?

Thx!

I am currently creating icons for Windows 11. To make it have the exact size of the default folder, I took a screen shot of the Extra Large Icon and drew over it using Inkscape. It has dimensions 179x141. But when I use GIMP + Iconify script which I got from here, the resultant ICO, when applied to a " New Folder " is slightly bigger than the default folder.

I tried numerous adjustments to the file size to correct this. Even used 2 other programs called Axilalis Icon Workshop and SimplyIcon. But in the end, no matter what I do, the ICO does not give the same size as the default folder.

It would be nice to know what is going wrong. Thanks.


PS : Attaching the PNG and ICO

please see attached, I have a jpg image with white background, l think I made all the white background transparent and now want to add the altered image to the 2nd layer in the project, but can't make it happen. maybe this isn't possible? thinking it should be simple but after trying for over an hour, coming here for help. tried moving it, copy/paste it, add it, etc. but no luck yet. the attached pic explain it best I think

I have the flatpak versions of GIMP 2.10.28 and Scribus 1.5.7 installed under Linux Mint Cinnamon 20.2. I wish to invoke GIMP from within Scribus to edit an image. The Scribus preferences allow me to define (in the External Tools option) the 'Name of Executable'. While I am not sure exactly what is meant here I assume it is the fully qualified path and name of the gimp executable that is required. I know of no way of definitively finding out what either of these two items of information is - for instance, the "flatpak info -l" option for gimp does not point to an executable, only a directory with an extensive tree structure 'below' it. I have used 'find' in Nemo, discovering more than 30 paths which might be relevant, out of approx. 2,900 'hits' on 'gimp' - but none of them work. Can anybody explicitly tell what what I should be using in Scribus? Has anyone actually ever done this?

I ask this because I had a similar challenge in trying to edit Gimp preferences to correctly invoke darktable 3.6.1 - but no one has so far been able to tell me what the correct string is, or even to prove (i.e. validate their claims)  that they have actually done it, with my installed versions of the apps under Mint 20.2. I have concluded that this is not possible with Gimp in this scenario.
