Description Alvin Wong 2017-10-03 13:54:50 UTC

I'm not very sure about this one. In the brush settings the graphs for X-Tilt and Y-Tilt have an x-axis range of -30° to 30°, but upon testing it appears to actually be (left to right) 60° to 0° of the absolute value of the tilt angle w.r.t the Windows tablet handling (I tested using pointer input events with the tilt fix patches, but it probably is the same for WinTab, but I am not really sure.)

Comment 1 Halla Rempt 2017-11-23 09:36:32 UTC

Qt at least puts it in the -60 to +60 range: http://doc.qt.io/qt-5/qtabletevent.html#xTilt

Comment 2 Dmitry Kazakov 2020-03-12 20:53:43 UTC

There is a "small" problem. Our "Tilt" sensor actually takes absolute value of the tilt. So, the actual range is 0...60deg.

The problem is going to be fixed in this MR:

Fix labels for xTilt and yTilt sensors

Actual range of our tilt sensors is -60...0 degrees. The range is
reversed to work better with size/opacity options.
