Resize an image in Java - Any Open Source Library?

BufferedImage createResizedCopy(Image originalImage,
    		int scaledWidth, int scaledHeight,
    		boolean preserveAlpha)
    {
    	System.out.println("resizing...");
    	int imageType = preserveAlpha ? BufferedImage.TYPE_INT_RGB : BufferedImage.TYPE_INT_ARGB;
    	BufferedImage scaledBI = new BufferedImage(scaledWidth, scaledHeight, imageType);
    	Graphics2D g = scaledBI.createGraphics();
    	if (preserveAlpha) {
    		g.setComposite(AlphaComposite.Src);
    	}
    	g.drawImage(originalImage, 0, 0, scaledWidth, scaledHeight, null);
    	g.dispose();
    	return scaledBI;
    }

BufferedImage scaledImage = Scalr.resize(myImage, 200);

Thumbnails.of("path/to/image")
    .size(100, 100)
    .toFiles("path/to/thumbnail");

Thumbnails.of(new File("path/to/directory").listFiles())
    .size(100, 100)
    .outputFormat("JPEG")
    .outputQuality(0.85)
    .toFiles(Rename.PREFIX_DOT_THUMBNAIL);
