In digiKam 1.0.0, a Batch Queue Manager is implemented with some base tools.

Fill a wish to bugzilla if you want to see a "Color Space converter"
in the future. And don't forget to explain exactly what the tool must
do... because we switch between bugs step by step and we become crazy
with all different situations to handle.

Please no need to be verboze. Go to essential. No need to write a book
(i remember a guy who has written around 200 lines in B.K.O to explain
what he want... the wish is purely dropped to the trash (:=)))

Best
