module proposal: gamut compression

[kofa (István Kovács)]

I didn’t say that

I know very little about colour, just experimenting. I’m certainly far from being knowledgeable enough to suggest such architectural changes.

I do know that LCMS has the reputation of being slow, but @ggbutcher experimented with their fast mode, and was happy with the results.

LittleCMS: fast_float is Fast!

I just finished incorporating the fast_float plugin into my LittleCMS integration in rawproc. Until now, I’ve been adding a proof group (resize, sharpen) to the end of my raw processing chains so I wouldn’t have to wait long for the display transform as I dorked around with filmic parameters. Don’t need to do that anymore; even on my slow Windows tablet, the display transform on the full-sized image is now way less than 1sec. I had to reorganize my display pipeline, my previous implementation…

I don’t know if that’d be useful for darktable and how much work / what dependency (library) changes would be needed to make use of it.
