CinePaint

CinePaint became its colour management during the work of Stefan Klein at the project. It is ICC based. As an offshot the Oyranos project was started to support interapplication conventions for colour management. This page describes CinePaints colour management.

Investigation

16-bit XYZ editing and displaying
print dialog needs system wide colour management
inconsitent colour UI for the legacy Gtk1 version (channel names, alpha handling, partitial colour space specific dialogs)
automate Cineon → ICC profile selection; currently manual
tonemapping
missed floating point precision colour transforms
