SYNOPSIS
eqn2graph [options]
DESCRIPTION
eqn2graph converts eqn equation descriptions into graphic images. It's a wrapper that processes eqn input through groff and converts the output to various image formats.
The tool reads equation text from stdin using eqn syntax and produces image files suitable for embedding in documents, web pages, or presentations.
eqn2graph is useful for generating standalone equation images without full document processing.
PARAMETERS
--format FORMAT
Output format: png, svg, pdf, etc.-s SIZE
Font point size.-unsafe
Allow unsafe operations.-v
Verbose mode.
CAVEATS
Requires groff and an image conversion tool (typically GraphicsMagick or ImageMagick). The default output format is PNG. Uses eqn syntax, not LaTeX math notation.
HISTORY
eqn2graph is part of the groff suite, providing a convenient way to generate equation images from eqn's preprocessor language.
