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

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.

So i just want to reduce the pixel count of an image from 16 megapixels to just under 2 megapixels. But there's a significant loss in quality of the image. Is there any way to not let this happen using gimp? Or if that's not possible via gimp, other free software or plugins that might help with this?

Hello,

A while back, I created this front cover for a book:



I'm trying to remember how I transformed the second half of the title: "Great Planetary Odyssey". It was straight at first (like the first part of the title: "Captain Gabriel") but then I curved it. I'm wondering how to reproduce the same effect on a different title. I tried doing it with the cage transform tool but I can't get it to look smooth with a perfect curve. Is there any other way to have this effect besides the cage transform tool?
