Description

Many SVS files are compressed using JPEG2000, which we do not currently support. Unfortunately, the JPEG2000 blocks in an SVS file use a color subsampling scheme not supported by JAI ImageIO or JJ2000 *the only two pure Java implementations of JPEG2000).

FreeImage ( http://freeimage.sourceforge.net) is an open-source C++ project that appears to fully support JPEG2000, including the variant found in SVS files. At the moment, this looks like our best option, assuming we can find a relatively simple way of deploying it.
