Just stumbled across an old reference to GSoC and JPIP and JJ2000...

http://dltj.org/article/gsoc-jpip/

This is the first of three posts summarizing the efforts of three students; this
one details the work of Juan Pablo Garcia Ortiz, a Ph.D. candidate at the
University of Almeria in Spain, to build a JPEG2000 JPIP Streaming Server and
Client Browser Viewer Applet. This is an edited version of his final report.

The final applications are the ‘jpip_serverL2‘ and the ‘J2KViewerL3‘ — both of
which can be found in the OhioLINK subversion repositoryL4. Please note that
both are built atop the Kakadu JPEG2000 code libraryL5, only a portion of which
is included in the OhioLINK subversion repository.


-------

So I was wondering how all this stuff turned out?  The JPIP server and viewer
seems to me to be a good way to view gigpixel panos.

And what about the effort to extract an all Java JPEG2000 decoder from JJ2000?

------
Pablo is currently collaborating a bit with the HiRISE projectL7 in order to
implement a pure Java JPIP code. It needs to use an efficient pure Java J2K
engine. They are currently modifing the JJ2000 code in order to improve it and
adapt it within the JPIP client. When this goal was reached, it should be
included into the current J2KViewer implementation.
-------

I'd like to get one of those.  I tried to do the same thing but threw up
my hands at the complexity of JJ2000 code.  Still have the remains of
my effort somewhere.  I stopped when I realized that a better approach
would be to start from scratch and reimplement the decoder.
