JPEG2000 to Zoomify Code4Lib Lightning Talk Video Now Available

Thanks, Noel, and everyone else who made the video editions of Code4Lib 2008 presentations possible. I just had a chance to notice that the video from my JPEG2000 to Zoomify Shim lightning talk was online:

Some updates since the post and the presentation were first done. The code that exists in the source code repository now was refactored to use JJ2000 as part of the Sun ImageIO package. We were seeing non-threadsafe problems with Kakadu and thought that using the multithreaded ImageIO package would help. Unfortunately, even with extensive caching, it did not. My next task is to bring Kakadu back into the picture using the threadsafe JNI implementation that is part of the ImageIO-ext project to see if that helps.

Unfortunately, time ran out before this needed to go into initial production with the OhioLINK DRC roll-out, so it isn’t in production. The scheme shows promise, though, so I’m going to keep working with it…
