pack-priv Class LinuxTouchTransform

extends Object
Class Inheritance
Imports
java.util.Arrays
Handles conversion between raw axis values received from Linux input devices and screen pixel values. By default input values are mapped form the device input range to the screen dimensions. The device input range can be overriden in using system properties of the form: monocle.input.PRODUCT_ID.KEY=VALUE PRODUCT_ID is the product descriptor received from udev KEY is one of minX, minY, maxX, maxY or flipXY flipXY is a boolean value; the others are integers.
