Convert SIXEL to X AVS

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.

The X file extension, also known as Application Visualization System X Image, is used for storing high-quality, true-color images with transparency. Developed by Stardent Computer for UNIX systems, it supports 32 bits per pixel, allowing for over 16,7 million colors with an alpha channel for transparency. This format is particularly valuable in scientific visualization and complex data representation. Despite newer formats, its uncompressed nature ensures image integrity without compression-related degradation.
