Pressure (Opacity) dynamic curve has a non linear response in the graph
Environment/Versions
- GIMP version: GIMP 2.10.28
- Package: Flatpak Fedora repository version
- Operating System: Linux, Fedora 35, Gnome
Description of the bug
The paint dynamics Pressure(Opacity) is not linear with the graph... when all environment is linear.
Reproduction
- Stylus pen setup of gnome and GIMP with a linear curve;
- Using the graph of paint dynamics, to enable only pressure x opacity;
- Do a constant curve along the x-axis and set different 'y' to make the stroke with different opacities.
…
Expected result: For each x-axis position, as the curve is linear, we wait for the same value on the y-axis and, this doesn't happen. The curve is not linear.
Actual result: See the figure of my result graph.
