The OpenJPEG library is an open-source JPEG 2000 codec written in C language. It
has been developed in order to promote the use of JPEG 2000, the new still-image
compression standard from the Joint Photographic Experts Group (JPEG).

Compatibility notes (for Developers):

The extended fields (jpwl) of the opj_cparameters_t and opj_dparameters_t
structures are only available when using the v2 main interface. Also you will
need to compile your code using "-DUSE_JPWL".

Developers writing programs for the v2 interface should use these functions
for allocating and freeing these structures:
 - opj_create_cparameters
 - opj_create_dparameters
 - opj_destroy_cparameters
 - opj_destroy_dparameters

Version 1 of the main interface is backwards compatible and will continue to
work as before except that there is now JPWL format support in the code.
