Convert FPX to SR

The FPX file extension stands for FlashPix Format, a bitmap image format developed in 1996 by Kodak, Microsoft, Hewlett-Packard, and Live Picture. It was designed to handle large image files efficiently by storing images at multiple resolutions within a single file, allowing quick access to the appropriate resolution based on display requirements. FlashPix uses Microsoft's structured storage format, which organizes hierarchical data in a single file. This format was particularly useful for digital photography and imaging applications, optimizing storage and bandwidth usage.

The Sun Raster (SR) file extension, is a raster graphics file format developed by Sun Microsystems for use on their SunOS operating system. This format, which stores black-and-white, grayscale, and color bitmapped data, was widely used in UNIX-based systems and supported by various imaging applications. The Sun Raster format includes a header, an optional color map, and the bitmapped image data. Although it does not support transparency, it remains a simple and widely distributed bitmap format.
