+Starting on 1.0.4, it can also be saved as a byte array, courtesy of code sent in by Paul Bowler:

 An important note is that the loaded image is never explicitly replaced after an operation - instead, a resulting image is created in the object. If you wish to apply more operations to the result, you should swap it with the originally loaded image.
