<P>
An image that stores its data as an integer RGB array internally, this image cannot be manipulated via Graphics primitives however its array is accessible and modifiable programmatically. This is very useful for 2 distinct use cases. <p>The first use case allows us to manipulate images in a custom way while still preserving alpha information where applicable. <p>The second use case allows us to store images in the Java heap which is useful for some constrained devices. In small devices images are often stored in a separate "heap" which runs out eventually, this allows us to place the image in the Java heap which is potentially more wasteful but might sometimes be more abundant. <p>Note that unless specified otherwise most methods inherited from Image will fail when invoked on this subclass often with a NullPointerException. This image can be drawn on graphics as usual
