Is it possible to shrink a selection to, for example, 1px width without the selection disappearing in the thinner areas?

Let me give you an example. In the image below, I have selected the "walls" at the edges of this map, shrunk that selection slightly and converted it to a path (in green). The problem is that when I convert it to a path, what I'd like is to instead have a single line through the middle of those walls, instead of two bordering the selection. But if I shrink it too much, some parts of the selection will completely disappear and I think that even if I managed that, the selection to path tool would create two lines anyway bordering the selection.

Perhaps a better question would be, can I create a path from a selection by filling in that selection instead of using the borders for the path?


Thank you!

Hello fellow Gimp users

I'm wondering if anyone can help me by recommending a drawing tablet for Gimp?  I'm using Windows 10 and the latest version of Gimp.  Does anyone use the Kamvas 13?  I've seen mixed reviews online with some saying it doesn't work with Gimp.

Thank you for any recommendations 

I was wondering if there was a plugin for Gimp similar to the Notes of Paint plugin for Photoshop by denis154. Or something on that end? Anyone know?

I was trying to quickly change the attached image file so that the whole background of this woman's head was fairly consistently light coloured.

I am trying to make the left hand side of the background (mostly dark brown and black) on the .xcf image of a woman in the attached file, stella_19apr.xcf [1] look roughly similar to the right hand side of the background (mostly pale pink/brown). To do this, I

1. Used the color picker to select a a pale brown/pink colour on the right-hand side, then

2. Tried to bucket fill some of the regions on the left-hand side.

But the bucket kept filling these areas with very dark brown or black and not the pale pink/brown I thought I had selected.

Could anyone tell me how I could fix this or begin to diagnose this problem?

(I can also see that in that image, I had used the eraser in an attempt to define a clear boundary between her hair and the background. This was how I was trying to prevent the bucket-filled pale brown/pink colour from flowing into the hair, but that is beside the point, here.)

Thank you for your attention.

i'm indexing an illustration with a 72 color palette.
The palette has a lot of colors covering well the color spectrum of the input illustration.
So I would expect to see all colors well associated after indexing.
Instead some of them turn very much despite the palette was equipped with colors very close to them.
An important example is light blue in attached files
How to solve?

Does anyone know any way to convert my raw images so I can edit and gimp as well as preserve the quality?

Thanks

Hi Ofnuts i'm trying to use your Replace-colormap but i get this error:

  GIMP Errore
Plug-in "ofn-replace-colormap.py"
(C:\Users\rnode1\AppData\Roaming\GIMP\2.10\plug-ins\ofn-replace-colormap.py)
attempted to install procedure "temp-procedure-number-8" with invalid parameter name "num colors".

  GIMP Errore
Errore di chiamata per la procedura "gimp-palette-get-colors":
La procedura "gimp-palette-get-colors" è stata chiamata con il valore "(null)" l'argomento "name" (#1, tipo gchararray). Questo valore è fuori limite.

I do following steps:
- indexing using a 24 color palette
- select new 24 palette from right panel
- Menu Color > ReplaceColorMap
error!

What i'm wrong? sure i'm missing some step
Thank you

Ooops...I deleted the thread instead of my last post. This the same question from another forum. Many apologies. - rich

We need to Convert the Color TIFF into JPEG (version 1.02). We have tried to converting the above format using some application, the version is not coming correctly (version 1.01 is coming). Customer requirement is JPEG 1.02.

So Kindly let us know any application for converting this format.

Hi,
using MAC Big Sur 11.2.3. and GIMP 20.10.22 there is a problem with the selection view.
I can't activate the selection view. Neither works shortcut (⌘ T) nor helps selection via Menue.

Also strange: All shortcuts seem to be deactivated (see red bubbles), wich is not true however. Except selection view they work, I tried.
THere are no checks showing up in front of the selected item/function, even if they are on (see blue bubbles).

Is this a bug with the new Apple System? Do I miss out any presetting?
Thanks for helping in beforehand!

   

I think I may need to take a break.  Time flies by, when I use Gimp, faster than seemingly any other task not related to real life.  Many computer tasks seem arduous and time drags to a halt. Oftentimes, even while doing something as normally enjoyable as browsing the Internet, time kind of slows down.

Not with Gimp though.  While doing anything in Gimp, I can be an hour into something, and I honestly think it's only been about 10 or 15 minutes. 

Another indication I may be Gimping too much is that when watching television, I constantly see scenes that I think I could make better in Gimp.   I start thinking about what filter I would run on this or that image I see in a commercial or on a show.  The font in that commercial looks outdated and it's not even centered or maybe it could use some stroking, etc...

I may see an old barn while driving or a building or even a tree, and think about how it would look better colorized in Gimp and could definitely use some curve and level adjustment. This or that street could do with some fresh stripes and some darkening of the asphalt.

Okay, "I" think I 've used I enough in one post and was just interested in if any of you have ever had times when Gimp was following you from the computer world over into the real world? I'm not asking for any psychological help  but am curious to know if you've ever used GIMP so much that you think about it away from a computer, tablet, or laptop screen?
