The new digikam image library DImg now supports ICC profiles using littlecms. littlecms is an open source color management engine which is used by krita as well and installed by default on most linux distributions. It was added by the new digiKam contributor Paco.
We will add a dedicated ICC profile setup page to the configuration dialog and a new image plugin to apply ICC profiles manually later.This is a companion discussion topic for the original entry at https://www.digikam.org/news/2005-11-21_dimg_framework_supports_icc_profiles/
