public class ImageData extends Object implements Serializable
Image or as a
byte[] array containing RGBA values
for each pixel (row/column order ?).
If bytes or Image is available use a Constructor -
otherwise use a factory method to load an image
from an Input source
Note: this class is immutable. The Constructors that have an image parameter just extract the data from the given image and don't reference it any longer. byte[] data is copied. Pending: do we want to keep the original image to pass out as RO instance?
