[Libpointing](http://libpointing.org) Node.js bindings

Libpointing is an open-source cross-platform library to get raw events from pointing devices and master transfer functions.

## Description

---

Libpointing is an open-source cross-platform library that provides direct access to HID pointing devices and supports the design of pointing transfer functions.

## Installation

---

* Install [libpointing](http://libpointing.org)
* npm install pointing

Note that, `pointing` with npm can be installed only on Mac OS and Linux.

## Example

---

	var pointing = require('pointing');

	if (process.argv.length < 5)
		console.log("Usage: node", process.argv[1], "[inputdeviceURI [outputdeviceURI [transferfunctionURI]]]")

	global.input = pointing.PointingDevice((process.argv[2]) ? process.argv[2] : "any:")
	var output = pointing.DisplayDevice((process.argv[3]) ? process.argv[3] : "any:");
	var tFunc = pointing.TransferFunction((process.argv[4]) ? process.argv[4] : "system:", input, output);

	input.setPointingCallback(function(timestamp, dx, dy, buttons) {
		var pixels = tFunc.applyi(dx, dy, timestamp);
		console.log(timestamp, dx, dy, buttons, " -> ", pixels.dx, pixels.dy);
	});

	var manager = pointing.PointingDeviceManager().addDeviceUpdateCallback(
		function(deviceDescriptor, wasAdded)
		{
			console.log(deviceDescriptor, wasAdded);
		}
	);
	var acc = pointing.SystemPointerAcceleration();
	console.log("Current acceleration for mouse:", acc.get());

	setTimeout(function() {
		console.log("Finished");
	}, 100000);
