That is pretty the same I was telling/suggesting in the other msgs, said
better :) I.e making -k having this behavior, user responsibility at
expense of gamut, and -K the opposite.
Yes I know the question: so why don't I stay with PM ?
1) argyll gray shades are more smooth and less bumpy than PM, given a
same used target for profiling. Even if argyll under some unlucky
circumstances can generate bumps in the darks.
2) with argyll I can measure a strip long even 50 cm and patches as little
as 8x6mm with my i1 pro and a custom ruler. With PM I simply can't, and
I'm restricted to bulky charts, wasting paper and time (at least, if
is there some trick I don't know!)
3) with argyll I can tweak parameters and I'm not limited to some basic,
unchangeable programmer's choice
4) argyll is open source and free, and the author takes care of user's rants
or suggestions or bug reports (and if one really wants, he can put his hands
in the source code too).
5) the effort of Graeme and/or whoever else decides to start a so complex
project is considerable and unvaluable.
...so that nobody can tell I'm just reporting problems, bugs or moans :)
