Convert SIXEL to MTV

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 MTV Raytracing Image Format, named after its creator Mark T. VandeWettering, is a simple, uncompressed true-color raster image format used primarily by the MTV Ray Tracer program. It employs the MTV or PIC file extension and is similar to the binary PPM format. Developed in the early days of ray tracing, the MTV format gained popularity due to its straightforward design and ease of use. It supports true-color images and is often utilized in conjunction with other ray-tracing utilities for rendering high-quality graphics.
