Convert RAF to SIXEL

The RAF file extension stands for Fujifilm Raw Image File, a format used by Fujifilm digital cameras to store uncompressed image data directly from the camera's sensor. Introduced to preserve maximum image quality, RAF files contain minimally processed data, allowing for extensive post-processing flexibility. This format, based on the TIFF/EP standard, includes metadata such as camera settings and format version. RAF files are primarily utilized by professional photographers and enthusiasts for high-quality image editing and archiving.

The SIXEL, or "six pixels", is a bitmap graphics format created by Digital Equipment Corporation (DEC) for their terminals and printers. Initially designed for DEC dot matrix printers like the LA50, it enabled the efficient transfer of bitmap graphics using a series of ASCII characters. Each character represents a 6-pixel high row, making it suitable for 7-bit serial communication. This format was later adapted for modern terminal emulators, extending its utility beyond its original scope.
