Convert AAI to CAL

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 CAL file extension, known as CALS (Continuous Acquisition and Life-cycle Support) Type 1 Image, is a 1-bit black-and-white raster image format developed by the U.S. Department of Defense in the mid-1980s to standardize graphics data interchange for military documentation. It is primarily used for storing and sharing monochrome images while retaining orientation metadata. The format supports both uncompressed and compressed (using CCITT Group 4 compression) images.
