Force parameter doesn't working correctly
Environment/Versions
- GIMP version: 2.10.28
- Package: Flatpak
- Operating System: Linux, Fedora 35 Gnome
Description of the bug
**Using the Force Slider on tool options dialog with stylus pen Wacom.**
The Force doesn't have a behaviour comprehensible ... the range from 0 to 40 is apparently linear but the range from 50 to 100 the curve has the same response, or rather, we have the same curve to all range force from 50 to 100 (with maximum k value, for instance).
When the dynamics are enabled with stylus pen
Apparently, the range of the Force slider on the Tool Options dialogue does not have any participation in the calculus to the whole range when is enabled a paint dynamic on the matrix.
The effect is always reproducible for all input parameters linked with force on the matrix (pressure, velocity, direction, tilt, random, fade).
Using the mouse with the paint dynamics enabled
With the mice is possible to use the force slider of tool options, see the figure where I have discretized the phenomena.
The waited for behaviour
Will be to have in all range of tool options force slider used to create variations on the alpha channel with enabled the paint dynamics of force matrix.
