Hello everybody,

with the help of AI I wrote a simple script for automating the first steps when processing polaroid pictures. Obviously AI is **** at this and I have no clue what I'm doing either, so I'm running into issues.

Apparently I can't post the script code here because the forum thinks it contains too many URLs for a new user - obviously there is no URLs here. I also can't upload it since the forum doesn't allow *.py files :/

I'll try adding the script as a separate post as an answer to this.

The script shows up correctly under Filters > Custom. But on execution nothing happens - I get no messages or error messages, neither in a terminal nor in the Error Console of Gimp. Additionally, obviously nothing the plugin is supposed to do executes - no renaming of the layers, no duplication, no filters get applied.

I would be very grateful for any hints pointing me in the right direction.

I am on Windows 10, running Gimp 3.0.4

Cheers
SofD

I indeed can't post the code here. I tried attaching as a *.txt file, But thats also not allowed. I would be very grateful for any help on how to share my code and also on how to improve it if I manage to share it.

Ai won't help you with GIMP3 scripts. AI needs training data. But there is hardly anything for GIMP3 yet.
Once you have, I think 5 posts here you can write URLs and attach scripts.
Thanks to all those spammers we unfortunately have this rule.

Yea, I noticed it was having a hard time.
But from my basic understanding the script it came up with looks fine.
The main things I want to do are:
renaming and duplicating the active layer.
running filter > despeckle
running filter > sharpen (unsharp mask)

maybe someone can point me in the right direction on how I should call these funnctions?

Code: Select all
active_layer = Gimp.Image.get_selected_layers(image)[0]


Code: Select all
new_layer = Gimp.Layer.copy(drawable)
Gimp.Image.insert_layer(image, new_layer, None, 0)


Code: Select all
f = Gimp.DrawableFilter.new(layer, "gegl:unsharp-mask", "")
filter_config = f.get_config()
filter_config.set_property('std-dev', 3.0)  # radius
filter_config.set_property('scale', 0.25)  # amount
filter_config.set_property('threshold', 0.0)
# layer.append_filter(f)
layer.merge_filter(f)


Haven't found anything for despecle :-(

The GIMP 3 API is here:
https://developer.gimp.org/api/3.0/libgimp/index.html
Just enter what you are looking for in the search box

GEGL operations ( like unsharp mask) are here
https://gegl.org/operations/index.html

As an example ... find foggify.py in your installation. That shows you some very basic plug-in stuff.

.... and despeckle goes like this:
Code: Select all
procedure = Gimp.get_pdb().lookup_procedure('plug-in-despeckle')
config = procedure.create_config()
config.set_property('run-mode', Gimp.RunMode.NONINTERACTIVE)
config.set_property('image', image)
config.set_core_object_array('drawables', [drawable])
config.set_property('radius', radius)
config.set_property('type', type)
config.set_property('black', black)
config.set_property('white', white)
result = procedure.run(config)
success = result.index(0)


Of course you have to fill in your variables here ;-)
