Description
DNL markers and what to do about them are explained nicely here: http://www4.informatik.uni-erlangen.de/Services/Doc/graphics/doc/jpeg/structure.html.
Java's native JPEG support conveniently does not support DNL markers, so it seems like the sensible solution is to pre-process the JPEG stream to strip out any DNL markers (and update the SOF markers) before passing the stream off to JIMI and the native JPEG decoder.
