14 # This script converts an SVG image to two files that can be processed
15 # with latex into high quality DVI/PostScript. It requires Inkscape.
18 # python svg2pstex.py [--unstable] [inkscape_command] inputfile.svg outputfile.eps_tex
19 # This command generates
20 # 1. outputfile.eps -- the converted EPS file (text from SVG stripped)
21 # 2. outputfile.eps_tex -- a TeX file that can be included in your
22 # LaTeX document using '\input{outputfile.eps_text}'
23 # use --unstable for inkscape < 1.0
26 # Do not use this command as
27 # python svg2pstex.py [inkscape_command] inputfile.svg outputfile.pdf
28 # the real EPS file would be overwritten by a TeX file named outputfile.eps.
31 # This script converts an SVG image to something that latex can process
32 # into high quality PostScript.
