Re: combining a File-Based LUT Transform and a Display Transform?

Paul,

It's simple enough as the display transforma are just specified as colorspaces.

I suspect that the swizzling is being done outside of ocio. You can just apply the standard image manipulation once it's loaded. So you can load a file, linearize it, apply exposure in linear, then move it to display space, and apply addition transforms, for gain offset gamma.

Or did I miss your question?

I saw in the Mari OCIO demo video they were able to load up a LUT and combine it with other display controls (gain/exposure). I can see how the LUT can be loaded using the FileTransform but how is it possible to combine that with a DisplayTransform with the other controls for gain/gamma and channel swizzling?

Are you guys doing your own gain/gamma/swizzling when using the File-based Transform?
