I installed a plugin to test it but I can't find it anywhere.
I looked inside the Python-Fu menu, I didn't find it.
Also in Filters - Python-Fu, without success.
In fact I'm not even sure what the name of this plugin would be.
Could anyone reveal the location of this plugin? Please!
Below is the plugin code:

Thx.
Python-Fu > Live Preview > Grow-Shrink Live (look near/at the bottom at Python-Fu, perso I did change the path to put it in "Select" instead of Python-Fu)
It's a nice script, but get quickly slow when moving the slider especially with big images and on my old computer, a recent computer is needed IMO

As above and in a Win 10 / samj 2.10.34 I have handy. I did copy the plugin from your post.
If it is not working, did you put the plugin straight into ...\Preferences\plug-ins ?
Did you perhaps put it in its own folder ? If so is the folder name the same as the plugin file name ?
Maybe in another folder ? Is that in your plugins path
...that is about all I can think of at the moment.
PixLab,
I had looked at the code and precisely for this line of code <Image>/Pyton-Fu.... One of the first menus I looked for the plugin was in the Python-Fu menu, but as I said I didn't find anything in that menu.
You said to look near the bottom... I looked again but couldn't find it.
In fact, I don't even know what name to look for this plugin.
rich2005,
I put it in the correct folder, the same one where all the other plugins are.
I didn't put it in a folder. I put it directly in the plugins/PluginsUso folder (the same for all plugins that install it).
Would I have to name it with a specific name? I named this plugin grow-shrink-live.py
It does not really matter what you have named the plugin file (excepting silly names) 123abc.py will do, it is the registration name in the code that matters.
Going back to where to find the plugin in the menu structure. Providing the plugin registers (that is not corrupt or not in your plugins folder) you can find from Help -> Plugin Browser.
All those other plugins in your screenshot work ? Just not grow-shrink-live.py Is that correct.
It might be when you copied / pasted the code. Did you use a text editor ? I got 194 lines start to finish
Yes!
With this other version, all the problems are gone.
Now everything goes as it should. Plugin easily visible in the menu as it should have been in the other version.

rich2005 thanks for solving another mystery. :-)
Krikor,
I have made a new (experimental) version of this program.
The maximum value of the slider is set to the size of the image.
When the program is run without a pre-existing selection is selects the compete image so "0" (zero) on the slider becomes maximum so that the selection can only be reduced.
The minimum of the slider I have tried to make so that it reduces the selection to only a few pixels.
If you wish to try it, your comments and criticisms would be very welcome.

Hi David,
Below are some observations. Sorry if they are not well organized or clear.
1- There is no way to cancel the plugin execution:
If I close the plugin window without clicking OK (by clicking the X in the window): -- A layer called "preview" with opacity of 70% is created. -- A channel called Selection Mask copy is created. -- The selection remains active with the values that were in the plugin before it was closed, and not with the values initially defined before the plugin was called.
Due to the above, I need to close the preview layer, close the Selection Mask channel, close the active selection, and I will still have to redo the selection again.
This makes it easier to just give OK anyway, since only the selection will have to be closed. (the preview layer nor the Selection Mask copy channel is created)
2- When the selection is being made on a background (a part of the image) with a color close to that used in the preview layer (for example, lips), the 70% opacity value ends up being a little high.
-- Fortunately, it is possible to adjust the opacity value while the plugin is still open.
-- However, if I notice, after making adjustments to the plugin (for example Grow = 4, Feather = 1) and reducing the opacity of the "preview" window to something around 30%; When I need to change these adjustment values, the opacity returns to the initial 70%, making it difficult to see the desired changes again.
Ideally, we would be able to adjust the opacity of the "preview" layer while adjusting the plugin values.
3-- I found it easier to move the sliders via the keyboard (<, >), which increments and decrements by one unit with each press.
4-- When there is no selection, the slider only allows the Skrink option (reduction), this is ok, but on the other hand it does not allow any change in the Feather Radius value.
-- Ideally, perhaps, in addition to being able to reduce the selection, it would allow the application of a Feather Radius if desired.
I only did a few tests with this plugin, and regardless of my considerations made above, I believe I will use it constantly as now I can have a better idea of which values to choose for the Grow/Shrink/Feather operations, which before it was guesswork and repetition.
David, thank you for taking the time to improve the usability of this plugin!

@ Krikor,
Thanks for your comments - I always find them helpful.
This is a plug-in by TinT. I have only made small alterations to try and set the limits for the sliders. Unfortunately the program has become unstable and I am unable to make other changes at present. (This may be the reason why you had problems installing the original program.)
When I have a stable program to work on, I shall examine your comments again.

@Krikor,
I have made a few changes to my previous version.
Ignore my comments about instability. The problem was a mistake in my code which TinT spotted!
The opacity of the mask is reduced to 50%.
It is now possible to change the feather setting when all the image is selected.
I have asked TinT to comment on my latest version, so I am certain he will make improvements to it!
