License

Internal/proprietary format used by Dune HD devices; format description is publicly available

AAI (Dune HD AAI Image) is an internal image format used in Dune HD devices to store simple uncompressed RGBA images with alpha transparency. The file contains width and height (32-bit integers) followed by raw 32-bit RGBA pixel data. It is mainly encountered when customizing Dune HD folders, Internet radio stations, and other UI elements. Images can be created with Dune’s AAImageGen tool or converted using utilities that support the AAI/Dune format.
