From 6aaba1066fe89f324d4bae67497f4035fe997d5f Mon Sep 17 00:00:00 2001 From: Yuta Doi Date: Mon, 11 Dec 2017 11:38:01 +0900 Subject: Add APIs which can get information of display and area getDisplayInfo() can get the display information as follows: - width[pixel] - height[pixel] - width[mm] - height[mm] NOTE: It uses wl_output::geometry() for getting physical width[mm] and height[mm] of the display, but the value is different with measured value. value from wl_output::geometry(): width:320 height:520 measured value : width:193 height:343 getAreaInfo() can get the information of area drawn by the application as follows: - x-coordinate - y-coordinate - width - height The details are described in doc/ApplicationGuide.md.
