Convert BIE to SR

The BIE file extension, associated with the Joint Bi-level Image Experts Group, stands for "Binary Image Entity". This format was developed for efficient compression of binary images, primarily used in fax transmissions. Introduced in 1993, JBIG1 provided lossless compression, outperforming earlier standards like CCITT Group 3 and 4. It was later succeeded by JBIG2, which offered improved compression efficiency for bi-level images.

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.
