A collection of utilities for converting between different display units. These functions are only useful on the Android platform to support devices with different screen densities and resolutions.
To use the measurement builtin library,
require it with the alloy root directory in your require call. For example:
var measurement = require('alloy/measurement'); var pointPX = {x:42, y:7}; var pointDP = measurement.pointPXToDP(pointPX);
