/**
 * Writes outs the image contained into this {@link ImageWorker} as a JPEG using the provided

 * <p>
 * The destination object can be anything providing that we have an {@link ImageOutputStreamSpi}
 * that recognizes it.

 * @param destination
 *            where to write the internal {@link #image} as a JPEG.
 * @param compression
 *            algorithm.
 * @param compressionRate
 *            percentage of compression.
 * @param nativeAcc
 *            should we use native acceleration.

 * @throws IOException
 *             In case an error occurs during the search for an {@link ImageOutputStream} or
