From source file:ImageOpByRomain.java

/**
 * <p>// w  w  w.  java  2  s .  c o  m
 * Returns a thumbnail of a source image. <code>newSize</code> defines the
 * length of the longest dimension of the thumbnail. The other dimension is
 * then computed according to the dimensions ratio of the original picture.
 * </p>
 * <p>
 * This method favors speed over quality. When the new size is less than half
 * the longest dimension of the source image,
 * {@link #createThumbnail(BufferedImage, int)} or
 * {@link #createThumbnail(BufferedImage, int, int)} should be used instead to
 * ensure the quality of the result without sacrificing too much performance.
 * </p>
