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

|
|
|
# This script converts an SVG image to something that latex can process
|
|
# into high quality PostScript.
