It should be 8 points (7 linear segments) in total. The value is hardcoded in brushlib/mapping.c and probably some other places (but not many). I think it's enough, a good approximation to some gamma-like curve should be possible. If not, it could be increased a bit (at the risk that there may be a brush compatibility problem). > Also, it seems I am unable to move the max and min pressure points > along the x axis, but they can be moved along the y axis. That's on purpose. If you were able to move the last point along the x axis, then you would no longer be able to see on the screen what output value the curve will take at an input close to 1.0. In the brush settings, the you can edit the y scale of the curve, to get around this limitation. This slider is missing in the preference (it would be hard to explain its purpose, too, few people get the brush setting already, but at least fewer users really need to understand those.) With the recent change in git that allows pressure above 1.0 to have an effect, maybe the curve in the preferences could be changed to have the ceiling at pressure output 2.0 instead of 1.0, allthough that might also be confusing. > Regarding individual pressures for each brush, I think this is is a > great idea.

That part is faster to implement than to discuss. It's in git master now: https://gitorious.org/mypaint/mypaint/commit/23d2de It's not auto-saved, though. And I'm not sure what is easier to understand as a label, "pressure gain" or just "pressure" or maybe "sensitivity". > Being able to decide if the brush uses local or global pressure > curve (which setting could be exported with the brush) would be > awesome. The trick is to have a good GUI concept for this. The global pressure curve will expected to have an effect on all brushes, I think. The auto-saving of brush settings may confuse the brush editing workflow... it has been discussed before, though, at least for the radius. I think there is even a bugreport about this. -- Martin Renold _______________________________________________ Mypaint-discuss mailing list [email protected] https://mail.gna.org/listinfo/mypaint-discuss
