Add NamedTransform support to ocioconvert #1863

Open doug-walker opened 1 year ago

doug-walker commented 1 year ago

Named Transforms are an alternative to color spaces and are used in the new OCIO configs for ACES. It would be helpful if the OCIO command-line tool ocioconvert added an option to apply a NamedTransform. Note that there should be an option to apply it in either the forward or inverse direction.

Need a bit of learning curve but I can tackle this ask for ocioconvert, please assign it to me.

Hi @doug-walker , Could you suggest a test that would show how the NamedTransform works?

doug-walker commented 9 months ago

@pennelee , please see this test. You basically ask for a NamedTransform object of the requested name from the config and then call getProcessor. Once you have the Processor, you can look elsewhere in ocioconvert to see how to apply pixels through it.

Hi @doug-walker , I have made changes in https://github.com/AcademySoftwareFoundation/OpenColorIO/pull/1988.
Please let me know your feedback, also if there are combinations of options that should work together. I thought not but not 100% sure. Thank you!
