Each of these solutions will take 250 to 500 ms to compute, depending on CPU. And, actually, we have 2 variables to find: mask exposure compensation and mask contrast compensation. So, it should be a parametric study of 5×5 solutions. So the first step takes 6 to 25 s to compute.
Another 1-2 s at very least.
- wait for people to complain that opening a new picture induces a 30 s lag before the preview appears.
Meanwhile, setting the thing manually takes like 10 s if it’s before your first coffee. Sometimes, I wonder if people take me for an imbecile or for an idiot. Again, if there was an easy good-enough solution, it would be coded already.
