Sixel Graphics

Sixel is a bitmap graphics format originally developed by DEC for the VT240 and VT340 terminals. It encodes raster images as printable ASCII characters, where each character represents a 1x6 pixel column — hence the name "six pixels." Sixel support has been revived in modern terminals (xterm, foot, WezTerm, mlterm) as a way to display inline images without requiring a proprietary protocol.
