I would like to convert about 500 pics in one directory with gimp and the GEGL - c2g FIlter. This one makes a nice black & white effect, if usesd with nice paramerters:
Radius: 1000
Samples 12
Iterations; 12
unfortunatly the filter is very slow, so make it foto by foto will take a lifetime :-)
How can I do it on the cvomandline as script or batch?
I am still notz knowing if this option is possible with the new GEGL-filters.
David's Batch Processor (http://members.ozemail.com.au/%7Ehodsond/dbp.html) or BIMP (http://www.alessandrofrancesconi.it/projects/bimp/) cannot do this, as far as I know.
http://www.gimp.org/tutorials/Basic_Batch/ (http://www.gimp.org/tutorials/Basic_Batch/) Was not a help either.
I use Gimp 2.8.
Thanks for your help
