As such it +only exposes a limited subset of its functions. It uses a mecanism 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/hidding function and as such the only +API available is the one supported by OpenJPEG. |
