Subject: ABS_MT_TOUCH_MAJOR metric
Date: Thu, 22 May 2014 14:03:40 +0300 [thread overview]
Message-ID: <537DD98C.5090800@cypress.com> (raw)
Hi,
What is the metric of ABS_MT_TOUCH_MAJOR / ABS_MT_WIDTH_MAJOR events?
The Linux documentation
<https://www.kernel.org/doc/Documentation/input/multi-touch-protocol.txt> says:
"The length of the major axis of the contact. The length should be given
in surface units. ..."
What does "surface units" means, is it millimeter or pixels?

Thanks,
