[Java]Pixelsearch

Kleine simple Pixelsearch Funktion die einen ausgew�hlten Bereich auf eine vordefinierte Farbe scannt und dann die Position des Pixels in Form eines "Point" zur�ckgibt. Ist zwar nicht das Schnellste, aber erf�llt seinen Zweck. :)

Code:

public static Point pixelSearchArea(String hexColor, Point topLeft, Point bottomRight) throws AWTException{
		
		int screenWidth = Toolkit.getDefaultToolkit().getScreenSize().width;
		int screenHeight = Toolkit.getDefaultToolkit().getScreenSize().height;
	
		int areaWidth = bottomRight.y - topLeft.y;
		int areaHeight = bottomRight.y - topLeft.y;

		Rectangle area = new Rectangle(topLeft.x, topLeft.y, areaWidth, areaHeight);
		
		Color colorColor = Color.decode(hexColor);

		int searchColor = colorColor.getRGB();

		Robot r = new Robot();
		Rectangle screenRect = area;
		BufferedImage bimage = r.createScreenCapture(screenRect);
		int width = bimage.getWidth();
		int height = bimage.getHeight();
		int[] colors = new int[width * height];
		int[] all = bimage.getRGB(0, 0, width, height, colors , 0, width);

		for(int i = 0; i < all.length; i++)
		{
			if (all[i] == searchColor)
			{
				int y = ((i + 1) / width);
				int x = (i) - (y * width);
				return new Point(screenWidth - (screenWidth - topLeft.x) + x,screenHeight - (screenHeight - topLeft.y) + y);
			}
		}

	return null;
