public abstract class ImgDataAdapter extends Object implements ImgData
This abstract class can be used to facilitate the development of other classes that implement 'ImgData'. For example a YCbCr color transform can inherit from this class and all the trivial methods do not have to be re-implemented.
If the default implementation of a method provided in this class does not suit a particular implementation of the 'ImgData' interface, the method can be overridden to implement the proper behavior.
