    I can't comment on whether JAI is overkill for your requirements -
    that would need more information. However, I can say that we've used
    javax.imageio.ImageIO with the TIFF plugin quite successfully. It's
    very simple - one method call to go between BufferedImages and TIFF
    files (or vice versa).

    You'll need the Image I/O API from

    http://java.sun.com/products/java-media/jai/current.html

    Put the jar file(s) on the CLASSPATH and the ImageIO.read methods will
    return BufferedImages from TIFF files.

    We've used it with 8- and 16-bpp TIFFs. Some software out there may
    produce TIFFs which don't conform to the spec e.g. 12-bpp (so the
    pixel data doesn't align with byte boundaries). The plugin won't work
    with such files.
