Convert SRF to JBG

The SRF (Sony Raw File) is a RAW image file format used by Sony digital cameras, such as the DSC-F828 model, to store uncompressed, unaltered images captured by the camera's sensor. Introduced in January 2004, SRF files preserve high-quality image data, offering photographers greater flexibility in post-processing compared to compressed formats like JPEG. Over time, Sony developed subsequent formats like SR2 and ARW to enhance features and compression methods.

The JBG file extension stands for Joint Bi-level Image Group, a format developed for efficient lossless compression of binary images, primarily used in fax transmissions. Introduced by the Joint Bi-level Image Experts Group, JBG files store 1-bit raster images and offer superior compression compared to older standards like CCITT Group 3 and 4. Although initially popular for fax machines, the format has largely been superseded by JBIG2, which provides even better compression.
