ePiX(1)

NAME
ePiX - A LaTeX pre-processor for creating mathematically accurate figures

SYNOPSIS
epix [-I<include>] [-L<libdir>] [-l<lib>] infile[.xp] [outfile[.eepic]]

DESCRIPTION
epix is a powerful, flexible, lightweight, text-based preprocessor for creating mathematically accurate, publication-quality line figures in LaTeX. Plots and picture objects are specified entirely in Cartesian coordinates, not in LaTeX picture coordinates. Output resizes robustly, and may include mathematical typography. epix uses enhancements to the LaTeX picture environment: Sunil Podar's epic.sty and Conrad Kwok's eepic.sty packages. Color figures may be generated from epix output with the pstcol.sty or color.sty packages. The included shell script laps converts LaTeX to PostScript. The shell script elaps converts .eepic to Encapsulated PostScript.

The source code, samples files, and primary documentation are available from the project home page:
    http://mathcs.holycross.edu/~ahwang/current/ePiX.html The latest stable version is also available from CTAN:
    http://www.ctan.org/tex-archive/graphics/epix

epix is implemented as a C++ library (libepix.a), header (epix.h), and a shell script (epix). An epix source file is a C++ program that calls high-level library drawing functions. Under direction of the shell script, the source file is compiled. The resulting executable prints the .eepic file, with output redirected to the specified file.

epix is primarily for 2-dimensional plotting. There is good-quality wire mesh plotting, but no hidden line removal yet.

PYTHON WRAPPER
Andrew Sterian has written a Python wrapper, pyepix that requires Python 2.2 but does not require either a compiler or GNU bash. pyepix (a *nix tarball and a Windows package) is available from the epix home page.

DOCUMENTATION
Complete documentation is distributed with the "complete" source package, and may be downloaded in several formats from the epix home page.
