I'm surprised nobody has hacked on that before. After all, it's all there: Parasites that gets saved with the image/layer, a python module that can update the editor-view live, a complete scripting language with gtk bindings.
I spend a handful of hours trying to make a proof-of-concept. See what you think.. http://www.artcamilla.dk/vaultage/cornucopia/gimp-plugins/layer-style.py 1) Make a test image with a background and a transparent layer with say a filled small rectangle. 2) Python-fu / Alchemy / Layer Style 3) Drag the slider 4) Close the dialog 5) Save the image and close it 6) Reopen the image 7) Select either the original gizmo layer or the auto-generated style layer 8) Invoke Python-fu / Alchemy / Layer Style again and play with the slider. There's a HUGE TODO list on that script, but the necessary basics are proven available although IT IS SLOW! But there are room for optimization, especially with a little help from the real pros who knows what is fast and what is slow. WARNING: Cheap tricks such as this will become obsolete once GEGL is ready, I can image.. :) Enjoy Centipede _______________________________________________ Gimp-user mailing list Gimpfirstname.lastname@example.org http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user
