Convert AAI to PHM

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 PHM file extension stands for Portable Float-map Image (16-bit half), a format used for storing High Dynamic Range (HDR) images with 16-bit half-precision floating-point values. This format is particularly useful in applications requiring precise color representation and extensive dynamic range, such as computer graphics, image processing, and scientific visualization. Originating from the Portable FloatMap (PFM) format, PHM was developed to provide a more efficient storage solution by utilizing half-precision floats, thereby reducing file size while maintaining significant detail and accuracy.
