API/ABI

OpenJPEG strives to provide a stable API/ABI for your applications. As such it only exposes a limited subset of its functions. It uses a mechanism of exporting/hiding functions. If you are unsure which functions you can use in your applications, you should compile OpenJPEG using something similar to gcc: fvisibility=hidden compilation flag. See also: http://gcc.gnu.org/wiki/Visibility

On windows, MSVC directly supports export/hiding function and as such the only API available is the one supported by OpenJPEG.
