Python-Fu Gimp 3.2.4. Get the active image - Burcador - 07-21-2026
Hi!
Question about Python-Fu Gimp 3.2.4
How do I get the active image (the one with focus) from all open images?

Its automatically included into the main function arguments by the initial procedure. In this function:
Code:
def my_function(procedure, run_mode, image, drawables, config, data) :"image" is the active image when you call the plugin.
What about during operation? - Burcador - 07-21-2026

"image" is the active image when you call the plugin.
No, not when the plugin is initialized.
My plugin launches a panel with buttons for launching several plugins.
While it's running, several images are open.
I'm switching between them.
The panel is open.
But how do I determine the active image so I can apply the plugin launched by the panel button to it?
The plugin only detects the active image upon startup. What about during operation?

That reads like this plugin https://www.chuckhenrich.com/custom-command-panel-gimp/
It is up to the user to choose the alternative image, which then brings up the plugin dialog.

Maybe have a look at the code, there might be something in it that you can apply to your project.

The plugin is excellent, thank you.
I'll use it.
However, the author also couldn't find a way to automatically detect the active image.
Instead, he suggests choosing from among the open ones to apply the plugin to, which you launch if you have multiple images.
Basically, I did it in a similar way, except I select the image before launching it.
. . .
But I'd like to find a more elegant way.

There were feature request about that:
https://gitlab.gnome.org/GNOME/gimp/-/work_items/16502
https://gitlab.gnome.org/GNOME/gimp/-/work_items/6572
so I guess it's not possible yet?

That seems to be the case.
All we can do is wait.

Honestly, I thought we had an PDB call for this as well.
This merge request may be of interest: https://gitlab.gnome.org/GNOME/gimp/-/merge_requests/2923
If merged, getting the active image would be Gimp.context_get_image () in Python.

I think there never was. I remember I struggled to get the active image in the python terminal in GIMP 2.10.

Scallact: Yeah, that seems to be the case. It was just surprising!
At any rate, the code's now merged, so after the next release people can use Gimp.context_get_image () and Gimp.context_set_image () as they like. Thanks everyone here for bringing it up!
