SVG to FIG Converter

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.
