How do you create a thumbnail for TIFF file in Java?

Question

Can someone please help with some code for creating a thumbnail for a TIFF in Java.

Using this Post I have created thumbnail for JPEG and PNG.

What have you tried? Why/how doesn't the code in the question you linked work? Post some code. — Philipp Reichart, Jul 16 '12 at 11:54
JavaIO can read TIFF files too. Just notice there can be several actual images in a single file. — Thorbjørn Ravn Andersen, Jul 16 '12 at 12:02

    BufferedImage image = ImageIO.read(aFile);
    BufferedImage thumbnNailImage = new BufferedImage(width, height,
            BufferedImage.TYPE_INT_RGB);

    Graphics2D g2 = thumbnNailImage.createGraphics();
    g2.fillRect(0, 0, width, height);

    double xScale = (double) width / image.getWidth();
    double yScale = (double) height / image.getHeight();
    double scale = Math.min(xScale, yScale);

    double x = (width - image.getWidth() * scale) / 2;
    double y = (height - image.getHeight() * scale) / 2;
    AffineTransform at = AffineTransform.getScaleInstance(x, y);
    at.scale(scale, scale);
    g2.drawRenderedImage(image, at);
    g2.dispose();
    return thumbnNailImage;

When reading ImageIO.read(aFile); always returns null.
