So device links aren't needed. This simplifies the
Device links are a serialisation of a color transform. lcms supports to dump color transforms to device links and load a device link into a color transform. Device link profiles come with little effort. Device links provide applications a entry to let the compositor do custom color space conversions on the GPU. > compositor requirements considerably (no need to support > buffers with up to 15 channels). Constrain device link to 3 in/out color channels as for the surface color space too. No need for 15 channels here. regards, Kai-Uwe Behrmann _______________________________________________ wayland-devel mailing list wayland-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/wayland-devel
