Convert AAI to CALS

The Dune HD AAI file extension, AAI, stands for Alpha-Alpha Image and is a raster image format used by Dune HD media players to display images with transparency, such as icons for Internet radio stations or channels. It stores 32-bit RGBA image data, which includes an alpha channel for transparency. This format is primarily used within Dune HD's ecosystem for organizing and displaying media content. The AAImageGen app, available from Dune HD, allows conversion of images like JPG, PNG, and BMP to AAI format.

The CALS (Continuous Acquisition and Life-cycle Support) Type 1 Image file format, developed by the United States Department of Defense in the mid-1980s, is a standard for storing raster (bit-mapped) image data, typically black-and-white. It ensures efficient data interchange and retention of orientation metadata. The format supports both uncompressed and compressed (using CCITT Group 4 compression) images. This standard was part of the broader CALS initiative aimed at improving electronic publishing and data management within the federal government.
