Convert AAI to PJPEG

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 PJPEG (Progressive JPEG) is a file extension for images that enhances the standard JPEG format by displaying images in successive waves of increasing detail, improving the user experience during slow network conditions. The JPEG stands for "Joint Photographic Experts Group", the organization that developed the standard in 1992. PJPEG is particularly useful for web applications, as it allows images to appear more quickly and progressively refine in quality, rather than loading from top to bottom like baseline JPEGs.
