Convert SVG figures to TiKZ

svg2tikz

Convert SVG figures generated by inkscape to TiKZ

Usage

python3 svg2tikz.py

A program to generate TiKZ code from inkscape-generated SVGs
Future plans include generalising to SVG without depending on Inkscape

positional arguments:
  INFILE                Input file

optional arguments:
  -h, --help            show this help message and exit
  --version             show program's version number and exit
  -d, --debug           Enable debugging messages (repeat for more messages)
  -a, --auto            Create output name from source
  -o OUTPUT, --output OUTPUT
                        Write to file(default is stdout)
  -b BORDER, --border BORDER
                        Set standalone border (default:1mm)
  -r DPI, --dpi DPI     Resolution (assume 72dpi)
  -R, --round           Round numbers to the nearest integer (default is 1
                        decimal)
  -M, --multi           Make a multi-slide LaTEX file
  -s, --standalone      Make a standalone LaTEX file
  -X XFORM, --xform XFORM
                        transformation applied to the SVG code (default:
                        yscale=-1)
  --code CODE           Output file coding

This script converts SVG to TiKZ drawings. In standalone mode, the result can then be converted to PDF using pdflatex (see Makefile). Otherwise, the result is a TeX file that is included into LaTEX documents (using the \input{} command)

MAIN SCOPE: The main scope of this script is files generated with Inkscape. I will make my best to parse other SVGs

Multi slide HOWTO

In order to create an animation from an Inkscape file

1. Create an inkscape figure.
2. Group objects you want to appear on each slide incrementally
3. Using the XML Editor in Inkscape, order the groups by order of appearance
4. Group all pages in one object. The structure should look like

 +-<defs>
 +-<g>
    +-<g>
    +-<g>
     ...

4. Add --multi when calling svg2tikz
5. In your Beamer presentation, \input{generated_tikz}

Tested with Inkscape up to v1.0beta2

Example: make multi will convert mount-ns.svg and compile test-multi.tex to create a multi-slide presentation

Limitations: Multi-slide standalone TiKZ files are not supported.

TODO

• arcs:
• Better support for rotation
• migrate to predefived XPath functions

Dependencies:

• Python 3
• LXML to parse the SVG files

svg2tikz's Issues

Getting empty tikzpicture

Trying to get the doi logo in tikz (see attach). Getting empty tikzpicture...
any help is welcome.
https://gist.github.com/ambs/9677eb6c7538dd0c7a9a12a27de854ed

Path does not show

Attaching an example where svg2tikz doesn't properly convert a path. The output tikz image has a \draw directive but no curve controls

test.zip

svg2tikz gives output:

Not able to convert

Hi,

I have a problem to convert this svg into tikz. It was generated the other way around (tikz -> svg)
http://blog.wikunia.de/user/pages/blog/2015-05-18-first-steps/xor.svg

My error messages:

python2 svg2tikz.py -a xor.svg

Unable to convert svg

I tried with this example and i got the following error:

line 946, in mkTikz
    self._unit = svg.xpath('string(//svg:svg/sodipodi:namedview/@units)',namespaces=self._nsmap)

Arrows come out the wrong way round

The arrows in the Inkscape document are the opposite way to how they are rendered when the LaTeX generated by svg2tikz is compiled.
