Thanks to this thread, now I know I create my own palettes using GIMP from images

viewtopic.php?f=8&t=17828

I have a couple of questions.

1. I just installed Ubuntu and GIMP. There is no palette tab on the right side dock. How can I bring one in ?

2. How can I create a colour palette from an image ?

a. Is it possible to set in which order colours will be arranged ?

Ok, I figured out. Now I have " Palette " dialogue and managed to learn how to create a palette by importing an image. But I am in the dark about how to sort the colours, unless you drag and drop using the cursor. Thanks.

This is a default Gimp 2.10.14 in a (k)ubuntu 18.04 (appalling isn't it, whoever devised that theme should be shot ;) However can be changed)
Click on any of the left pointing arrows and you can add tabs including the palette dock.

Then to import a palette, right click in the dock, choose import, and apply the dialogue

Sorting? Yes but probably not the way you need.

Those options are python plugins. How did you install Gimp in your Ubuntu?
Check in Filters menu Is there a Python-Fu entry (just above Script-Fu)?

I installed GIMP through PPA from kesselgulasch. I tried filters > script-fu. Please see the gif below

You do not have gimp-python installed.

In a terminal

sudo apt install gimp-python


and if you want the mypaint brushes

sudo apt install mypaint-brushes

@rich2005

What does gimp-python do ? Those script-fu features you mentioned ? Thanks.

Python-Fu lets you run python plugins. 'some-name'.py There are hundreds of these that do all sorts of functions. There are a few already included in Gimp and those palette entries are some of them.

If you ever download a python plugin in linux it goes in ~/.config/GIMP/2.10/plugins (~ is shorthand for your home partition) ~/.config is a hidden folder. You can show hidden in your File manager. In linux a python plugin has to be made executable. You can do that in your File Manager as well.

Script-Fu scripts are 'some-name'.scm There are hundreds of these as well. They go in ~/.config/GIMP/2.10/scripts

The two entries Python-Fu and Script-Fu in the Filters menu let you access command terminals. Do not worry about using that until you know what you are doing.
