public Raster getData()
The returned Raster is semantically a copy. This means that updates to the source image will not be reflected in the returned Raster. For non-writable (immutable) source images, the returned value may be a reference to the image's internal data. The returned Raster should be considered non-writable; any attempt to alter its pixel data (such as by casting it to WritableRaster or obtaining and modifying its DataBuffer) may result in undefined behavior. The copyData method should be used if the returned Raster is to be modified.
