Constructor & Destructor Documentation

◆ LcmsEnginePlugin()

LcmsEnginePlugin::LcmsEnginePlugin ( QObject * parent,
const QVariantList &  )

By default we remap the legacy HDR profile into the new Rec2020PQ profile with CICP values. This profile will also have CRWL tag set to the official 203 nits. The legacy HDR profile loaded from older .kra files will have a different mapping to map to 80 nits used in Krita previously.
