GIMP Script-Fu that exports layers to separate files. You can select desired layers with visibility or/and linking.
Place the script file in to the Gimp scripts directory. You can find it in the preferences.
Edit -> Preferences -> Folders -> Scripts
The export dialogue accessible through the Script-Fu -> MHL-Export layers menu.
You can point a directory to where export layers, how to name files,
specify a file type.
Also if you have selected the desired layers with visibility or/and linking,
then you can set the corresponding switches. Or turn them off when you want
to export all layers.
This is a simple alternative for the kamilburda/gimp-export-layers plug-in. And it can save you some time when you don't want to install Python2 😄.
