Convert MEF to BIE

The Mamiya Electronic Format (MEF) is a raw image file format used by Mamiya digital cameras to store unprocessed and uncompressed image data directly from the camera sensor. Introduced in the mid-2000s, MEF files maintain the original scene's dynamic range and quality, allowing professional photographers extensive post-processing control. These files are typically large due to their uncompressed nature and include vital metadata such as exposure settings and white balance. MEF files are commonly edited using specialized software like Adobe Photoshop and Lightroom.

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.
