+## What is OpenJPEG ?
OpenJPEG is an open-source JPEG 2000 codec written in C language. It has been developed in order to promote the use of [JPEG 2000](http://www.jpeg.org/jpeg2000), a still-image compression standard from the Joint Photographic Experts Group ([JPEG](http://www.jpeg.org)). Since April 2015, it is officially recognized by ISO/IEC and ITU-T as a [JPEG 2000 Reference Software](http://www.itu.int/rec/T-REC-T.804-201504-I!Amd2).

## API/ABI
+An API/ABI timeline is automatically updated [here][link-api-timeline].

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
API available is the one supported by OpenJPEG.
