hi
until fw 4.4.565 (excluded) there was 6 parameters in global.cfg file that could be tuned:
gamma, mincontrastlevel and maxcontrastlevel
either for Adobe and Djvu
so the previous scripts I posted modified those parameters
The script was for testing best combination of them, provided that up to now only gamma change seems to have effect.
Now (from fw 4.4.565) in global.cfg there is only the gamma level for Adobe. More, you can change it via the PB settings (with step of 0.2, from 0.2 to 2.6)
So the new script allows to change only the gamma for Adobe, albeit on an arbitrary base: no step (you can put how much decimal you like) no sign (it accept also negative numbers that adobe accepts too)
No change in the DJVU part
