Class ImageHistogram
java.lang.Object
jsky.image.ImageHistogram
public class ImageHistogram
- extends java.lang.Object
Utility class used to avoid creating the same Histogram twice
(Once for auto-setting cut levels and once for histogram equalization, if selected).
The previous arguments and resulting histogram are cached and compared the
next time getHistogram is called. If the arguments have not changed, the cached
Histogram is returned.
