Dear GDAL Developers, I am developing a new open source JPEG 2000 toolkit, based on OpenJPEG.
It is a drop-in replacement for OpenJPEG, but features: - fast precinct-level decode - lower memory usage - better performance - currently it is roughly 1/3 the perf of Kakadu, (tested on windows), and I am hoping to get it down to around 1/2 I was originally hoping to merge these changes into OpenJPEG. For a number of reasons, I decided to start a new project instead. One of my main motivations is the fact that OpenJPEG is a reference implementation, designed for correctness and portability. My main interest is performance. I have ported the code to C++14, so developers get access to all of the modern C++ goodness such as class hierarchies, lambdas, threading library, exceptions, standard template library, etc. Gone is support for older compilers, including VS 2010. The code is licensed under the AGPL, to ensure that all code modifications get contributed back to the community. It you find this useful, please visit https://github.com/GrokImageCompression/ronin For those who need a more permissive license, or who prefer using the reference implementation, there is always good old OpenJPEG. Kind Regards, Aaron
