Convert BMP to SIXEL

The BMP (Bitmap Image) file extension is a raster graphics format used primarily for storing digital images. Developed by Microsoft, BMP files retain high image quality due to their lack of compression, making them ideal for preserving detailed and colorful images. Introduced in the early days of Windows, BMP's simplicity and widespread compatibility have cemented its role in digital imaging, despite being superseded by more efficient formats in many applications.

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.
