How can I create plugins for GIMP?

Creating plugins for GIMP involves using the Script-Fu or Python-Fu scripting languages. Do you have a specific functionality in mind?

I want to create a plugin that adds a custom filter.

You can start by defining the filter's parameters and then use the GIMP API to manipulate the image. Would you like a code example?

Yes, please provide a simple code example.

Here's a basic example in Python:

from gimpfu import *

def custom_filter(image, layer):
    # Your filter logic here
    pass

register("python-fu-custom-filter", "Custom Filter", "Applies a custom filter", "Your Name", "Your Name", "2023", "Custom Filter", "RGB*, GRAY*", [], custom_filter, menu="<Image>/Filters/Custom")

main() 

This registers a new filter in the GIMP menu.

How do I install this plugin in GIMP?

To install the plugin, save the script in your GIMP plugins folder, usually located at ~/.config/GIMP/2.10/plug-ins/. Make sure it's executable, then restart GIMP.
