A theoretical question: can CinGG be adapted to work in Wayland or is it impossible? Has XWayland limitation?
OK, perhaps I've understood. Your question is not about just color correction according to an ICC profile, it is about direct rendering of HDR where the complete tone mapping is to be done by the graphics driver (not by NLE) which must support both CMS and HDR. This is quite different thing, I know nothing about this perspective. As long as I understand, the current photo (not video) processing software for Linux works so. It takes camera profile from somewhere. ArgyllCMS calibrates the monitor and creates the monitor profile. The photo processing program converts RAW photos from the camera, taking into account the camera profile, to some kind of HDR (internal format) in memory. The photo processing program does all the effects through the photo developing pipeline. At the end, the program most probably, if there is no goal to save in EXR format or 16-bit TIFF, converts it to sRGB. Then, either the program itself applies the monitor profile to display the corrected image, or the program simply displays, while the correction is performed by colord. And there is a third possibility: the program applies the monitor profile, then colord applies it for the second time, and the resulting colors come wrong. _______________________________________________________________________________ Georgy Salnikov NMR Group Novosibirsk Institute of Organic Chemistry Lavrentjeva, 9, 630090 Novosibirsk, Russia Phone +7-383-3307864 Email [email protected] _______________________________________________________________________________
