[Linuxwacom-devel] [PATCH] Scale up touch width and height values for Intuos Pro
|
From: Jason G. <kil...@gm...> - 2013-09-25 23:22:38

The width and height values reported by the Intuos Pro are not in
surface units as required by the MT protocol. A simple multiplier
of 100x seems to be approximately correct based on my tests.
