I do know something about gimp-2.9. Neither script-fu nor python-fu are being "maintained". An example of this is that it is no longer possible to convert an image from RGB to GRAY due to an extra color profile parameter required by GIMP. And I read of similar problems with script-fu (although that might be a new notation for layer modes). On the layer modes! That is where gimp-2.9 is crazy different than all other GIMP! Color erase has performed miracles for me. As you work through solving this problem of yours, take a look at these new layer modes. The answer you need might be in there. carol _______________________________________________ gimp-user-list mailing list List address: gimp-user-list@gnome.org List membership: https://mail.gnome.org/mailman/listinfo/gimp-user-list List archives: https://mail.gnome.org/archives/gimp-user-list
