From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux 2.4.3-12 i686; en-US; 0.7) Gecko/20010316 Description of problem: The colortoalpha plug-in cannot be invoked with the RUN_NONINTERACTIVE mode (i.e. from script-fu). It always fails with a PDB call error. How reproducible: Always Steps to Reproduce: 1. Open script-fu console 2. Invoke "(plug-in-colortoalpha RUN-NONINTERACTVE image layer color)" (image, layer, and color values chosen are unimportant) 3. Watch it fail. Additional info: A patch which fixes the problem (against gimp-1.2.2) is attached. I have also submitted this patch to the plug-in author, but figured (particularly with the new public beta) I'd let you guys know as well..
Created attachment 27394 [details] Patcb to fix colortoalpha plug-in RUN_NONINTERACTIVE mode
I guess this should be fixed in current GIMP ;-).
