- Description
- The PR file type, associated with Sun Icon/Cursor, refers to a specific format used to store icons and cursor images on systems that supported Sun Microsystems' graphical environments. These files typically contain bitmap images designed for use as graphical user interface elements, such as icons for applications or interactive cursors for mouse pointers. The format is tailored to the needs of Sun's software and hardware platforms, which were prevalent in the 1980s and 1990s, particularly in academic, engineering, and enterprise environments. Despite its historical significance, the PR file format is less commonly used today, given the evolution of computing technology and graphical standards.
- Image stored in the JPEG XR format, which was originally developed by Microsoft for Windows Media software; supports deep color images with 48-bit RGB; used for high-resolution professional image editing; also supports lossless and lossy compression.
