Hello,
I was digging around trying to find out if darktable is able to make a grid from 24 cells to 140 cells (to match a colorchecker chart) and then extract the RGB values from it. I would like this to be able to list row column and then the RGB values (and maybe some basic stats, min/max/average). I'm after something similar to what rawdigger can do, but with jpeg and raw file formats. I'm open to other programs as well.
example from rawdigger:
