I need to perform some high quality, image resizes (with the use of the Lanczos3 and sometimes the Mitchell algorithms). I have managed to achieve this with just Java (with the use of JIU (http://jiu.sourceforge.net/
However, it takes quite a few seconds (approx 10) to resize an image, at 100% CPU usage.
As a result of this lag, I thought that I could get the job done quicker and more efficiently, if I were to use some C++ to do the Image resize (with this algorithm) ... I know how to share String, int, etc, instances, but how to share Image instances with C++? I haven't come across a jimage type in the jni.h file yet; lol, I'm guessing it can't be done? :o\
