		## Example Usage
		## Streaming API - Duplex Piping with Writes

		You can also stream writes of pixel data (or canvas contexts) to the encoder:

		``` js
		var GIFEncoder = require('gifencoder');
		var Canvas = require('canvas');
		var fs = require('fs');

		var encoder = new GIFEncoder(320, 240);
		encoder.start();
		encoder.setRepeat(0); // 0 for repeat, -1 for no-repeat
		encoder.setDelay(500); // frame delay in ms
		encoder.setQuality(10); // image quality. 10 is default.

		// use node-canvas
		var canvas = new Canvas(320, 240);
		var ctx = canvas.getContext('2d');

		// red rectangle
		ctx.fillStyle = '#ff0000';
		ctx.fillRect(0, 0, 320, 240);
		encoder.addFrame(ctx);

		// green rectangle
		ctx.fillStyle = '#00ff00';
		ctx.fillRect(0, 0, 320, 240);
		encoder.addFrame(ctx);

		// blue rectangle
		ctx.fillStyle = '#0000ff';
		ctx.fillRect(0, 0, 320, 240);
		encoder.addFrame(ctx);

		encoder.finish();

		var buf = encoder.stream().getData();
		fs.writeFile('myanimated.gif', buf, function (err) {
		// animated GIF written to myanimated.gif
		});
		var encoder = new GIFEncoder(854, 480);
		var bitMapStream = makeMyBitMaps(); // read stream that creates RGBA 1-dimensional bitmaps
		bitMapStream
		.pipe(encoder.createWriteStream({ repeat: -1, delay: 500, quality: 10 }))
		.pipe(fs.createWriteStream('myanimated.gif'));
