selection to neon glow

This is a GIMP Python plug-in to create neon glow effect based on a selection. Turn selected region into lightsaber or 80s cartoon underlighting (aka "Bipack Glow") effects.

How to use it

Download and install GIMP and copy the file selection_neon_glow.py into the following directory:

Windows (all users)
%PROGRAMFILES%\GIMP 2\lib\gimp\2.0\plug-ins\
Windows (single user)
%USERPROFILE%\AppData\Roaming\GIMP\2.10\plug-ins\

Linux
~/.config/GIMP/2.10/plug-ins/

After you've put the file in the plug-ins directory, open GIMP and there should be a new menu item available, under Script-Fu -> Selection to neon glow.

Known bugs / trouble shooting

There is a bug in GIMP for Windows 64bit causing an error when selecting a color from the plug-in dialog. When clicking on the color widget will give an eror message "unable to run GimpPdbProgress callback", this bug has been reported.

When merging the new layers into a single layer, it somehow looks less "glowy". Don't know what causes this, possibly a bug in GIMP, if anyone knows why please let me know.
