About formats

FIG is the native file format of Xfig, a free vector graphics editor for the X Window System, originally written by Supoj Sutanthavibul at the University of Texas at Austin in 1985. The format uses a plain-text structure where each graphic object is described on one or more lines with numeric parameters specifying object type, coordinates, line properties, fill attributes, and depth ordering. FIG supports compound objects (groups), polylines, polygons, splines, arcs, ellipses, text strings, and imported bitmaps, each with configurable colors, line styles, arrow heads, and area fills. Files begin with a header line declaring the format version (currently 3.2), followed by a resolution specification and the object definitions. One advantage is exceptional simplicity — the entirely text-based format is trivially parsed, generated, and manipulated by scripts, making FIG popular as an intermediate format in automated diagram generation pipelines. The rich ecosystem of conversion tools is another strength: fig2dev exports FIG files to dozens of output formats including EPS, PDF, SVG, LaTeX picture environments, PSTricks, and TikZ. This made Xfig and FIG especially popular in academic and scientific communities, where authors generate publication-quality figures that integrate seamlessly with LaTeX documents. While graphical tools have evolved since the 1980s, FIG remains in use among researchers who value its scriptability, LaTeX integration, and well-documented format stability.

SIX is a file extension for SIXEL (Six Pixel) graphics data, a bitmap graphics format developed by Digital Equipment Corporation (DEC) in 1983 and introduced with the LA50 dot matrix printer. SIXEL encodes images as a sequence of printable ASCII characters, where each character represents a column of six vertical pixels (a 'sixel') — the character's ASCII value minus 63 provides a 6-bit binary pattern, with each bit controlling one pixel in the vertical column. The encoding is structured as a series of sixel bands (each six pixels tall) across the image width, with control sequences for color selection (up to 256 registers with HLS or RGB specification), repeat counts (run-length encoding for efficiency), carriage return, and newline commands. SIXEL data is transmitted to the output device using DEC's standard escape sequence protocol, embedded within the text stream alongside regular character output. Originally designed for DEC's line of printers and later supported by DEC VT-series terminals (VT240, VT330, VT340), SIXEL has experienced a remarkable revival in modern terminal emulator software. One advantage is terminal-native image display: SIXEL allows images to be rendered directly within a text terminal session without requiring a graphical window system, enabling command-line tools to display graphs, photographs, and previews inline with text output. This capability has driven adoption in modern terminals like mlterm, xterm, WezTerm, and foot. SIX/SIXEL data can be generated by ImageMagick, libsixel, and chafa, and viewed in any SIXEL-capable terminal emulator.
