Convert JFIF to SIXEL

The JPEG File Interchange Format (JFIF), developed by the Joint Photographic Experts Group, is a standardized method of storing and transferring JPEG-compressed images. Introduced in 1991, JFIF ensures compatibility and interoperability among different platforms and applications. It is extensively used in digital imaging and multimedia for efficient image compression, which reduces file size without significant loss of quality. As a widely adopted format, JFIF supports a range of devices and software, making it a cornerstone in computer graphics and online image sharing.

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.
