Kinectにてユーザ領域のマスク（WriteableBitmap）を生成する

よくあるテキスト等で書かれている処理ですが、ユーザ領域のマスクを作っておくと、後々便利なことがあったりしますので、、、、

	public WriteableBitmap createPlayerMaskWBitmap(DepthImagePixel[] depthImagePixels, ColorImagePoint[] colorImagePoints) {
	int width = KINECT.DepthStream.FrameWidth;
	byte[] outputColor = new Byte[KINECT.ColorStream.FramePixelDataLength];
	WriteableBitmap testBitmap = new WriteableBitmap(colorFrameWidth, colorFrameHeight, 96, 96, PixelFormats.Bgr32, null);
	for (int i = 0; i < depthImagePixels.Length; i++) {
	int colorIndex = ((colorImagePoints[i].Y * width) + colorImagePoints[i].X) * 4;
	if (depthImagePixels[i].PlayerIndex != 0) {
	outputColor[colorIndex] = 255;
	outputColor[colorIndex + 1] = 255;
	outputColor[colorIndex + 2] = 255;
	outputColor[colorIndex + 3] = 0;
	} else {
	outputColor[colorIndex] = 0;
	outputColor[colorIndex + 1] = 0;
	outputColor[colorIndex + 2] = 0;
	outputColor[colorIndex + 3] = 0;
	}
	}
	testBitmap.WritePixels(ColorImageBitmapRect, outputColor, ColorImageStride, 0);
	return testBitmap;
	}
