Convert DVI to SVG with dvisvgm issue - svg

Question

I try to use below steps to get a SVG file but it seems the output SVG file not displayed correctly.
Use latex to compile latex code test.tex to dvi file.
\documentclass{standalone}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\def\r{2cm}
\node (O) at (0,0) {$O$};
\draw (0,0) circle (\r);
\draw[->] (-\r,0)--(\r,0);
\draw[->] (0,-\r)--(0,\r);
\end{tikzpicture}
\end{document}
Compile to dvi (test.dvi) with below command line:
# latex test.tex
use dvisvgm tool to convert dvi file to SVG (test.svg).
# dvisvgm --no-fonts test.dvi
The SVG file seems created successfully but it only display a O character in Chrome Browser or Firefox.
So I guess the SVG file maybe something wrong.
The SVG file content as below:
<?xml version='1.0' encoding='ISO-8859-1'?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">

Anything wrong with dvisvgm command?

Answer 1

You probably ran dvisvgm with deactivated PostScript support. You can find further information on how to check this on the dvisvgm FAQ page. With activated PS support, I get the correct result:

Answer 2

The SVG looks fine. It has only one graphical element in it (the path) and it gets drawn correctly by the browser(s).
So that would suggest that there is something wrong with your latex file or the conversion tool. I don't know latex well enough, so I can't help with that.

Answer 3

Oh,that means I didn't install Ghostscript tool in my MAC.
I try to install ghostscript to MAC with below command:
# sudo port install ghostscript
The install seems work fine but it seems only /usr/local/gs file created, no share library at all.
Then I try to check dvisvgm libgs settings:
# dvisvgm -h |grep libgs
--libgs=filename set name of Ghostscript shared library
# dvisvgm -l |grep gs
Notes:Nothing output for this command.
That means I need to use a --libgs=filename option to specify the share library.
Does that means dvisvgm tool can not work in MAC?
I have tried to compile ghostscript from source on MAC but compile failure.
Then I try to use MAC version gs to convert pdf to SVG, it seems segment fault:
# gs -dBATCH -dSAFER -dNOPAUSE -sDEVICE=svg -sOutputFile=test.Svg test.pdf
....
Segmentation fault: 11
And inkscape seems works fine with below command:
inkscape test.pdf --export-plain-svg=test.svg
inkscape really do good job on MAC bit a bit time consuming.
