Bug ID: 361293
Summary: Wacom Airbrush wheel returning negative value and
krita creates a negative brushsize
Product: krita
Version: git master
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: minor
Priority: NOR
Component: tablet support
Assignee: krita-bugs-n...@kde.org
Reporter: bloodyw...@tastyespresso.de
The Wacom Airbush Pen returns a integer (or float?) range with can be negative
or positive
lowest value is -255 and highest +255.
The range 0 - 255 works just fine in krita but when I scroll further with the
airbrush wheel it returns a negative number and krita increases the brush size
according to the negative value.
But you can't draw with that negative brush size.
Reproducible: Always
Steps to Reproduce:
1. Map the airbush wheel to the brush size in the brush editor
2.
3.
Actual Results:
Brush size is displayed the same as it's positive counterpart but. The result
is that only half of the brush wheel is usable.
Expected Results:
the lowest negative size in tangential pressure should be the smallest brush
size in that case.
I'm not quite sure if the airbrush returns -1.0 and 1.0 or -255 and 255
Other devices could work with this since they return a range with 0 - 255
