Not a tutorial, just my thoughts.
I don't know if you want these but scripts/plugins used
gmic_gimp_qt from http://www.gmic.eu
anitools.py is on the old gimp plugin-registry site but is a pain to find. This will add alpha to all layers as shown and also write layers to individual png's if required.
color-to-alpha-for-all-layers is a rough script I found. Make sure bottom layer is active before using. see the attached zip for those two
Adding a background layer was using Ofnuts plugin interleave-layers-0.4.py from http://sourceforge.net/projects/gimp-too...s/scripts/ worth a look there, all good stuff.
As I see it, the hurdle for any batch operation is the pesky need for a selection to constrain any effect. The gmic filter works on transparency so if you can create those transparent areas some other way, then the selection would not be necessary and gmic standalone (different from the gimp plug-in) will run from a bash file.
The maintainer of gmic is on vacation at the moment but a good way of asking the question is at http://gimpchat.com in the plug-ins/gmic section. I am sure somone there has better ideas, best of luck
