Convert sympy results to svg string

[Anton Makarov]

Hi, i am new to sympy. I need to convert the results of sympy calculations to svg string.

How can i do this?

[Anton Makarov]

I'm taking about result of calculations, for instance:

expr = sympify("1+2/3*sin(x)")

result = str(expr)

and i need to convert result to svg. How can i do this?

Are you trying to convert typeset math into a scalable vector graphic image (.svg) or do you mean something else?

[Anton Makarov]

I need to convert sympy tree expression to svg, for instance:

a = sympify("1+2/3")

b = sympify("x+5/x+3*sin(x)")

c = a + b

and i need to convert c expression to svg string

I don't want an svg file, i want the string. Something like this:

svg_string = <svg width="134" height="32" viewBox="-1 -1 134 32"><path d="M 0 14.3 L 7.169531 14.3 " fill="none" stroke="rgb(0,0,0)" stroke-width="1"></path><text x="0" y="9.962011" font-family="'Segoe UI'" font-size="13.3" textLength="7.169531" fill="rgb(0,0,0)">5</text><text x="0" y="26.26201" font-family="'Segoe UI'" font-size="13.3" textLength="7.169531" fill="rgb(0,0,0)">3</text><path d="M 11 15 L 21 15 " fill="none" stroke="rgb(0,0,0)" stroke-width="1"></path><path d="M 16 9.8 L 16 19.8 " fill="none" stroke="rgb(0,0,0)" stroke-width="1"></path><text style="font-style: italic" x="25.16953" y="18.28633" font-family="'Segoe UI'" font-size="14" textLength="6.371094" fill="rgb(0,0,0)">x</text><path d="M 36 15 L 46 15 " fill="none" stroke="rgb(0,0,0)" stroke-width="1"></path><path d="M 41 9.8 L 41 19.8 " fill="none" stroke="rgb(0,0,0)" stroke-width="1"></path><path d="M 49.54063 14.3 L 56.71016 14.3 " fill="none" stroke="rgb(0,0,0)" stroke-width="1"></path><text x="49.54063" y="9.962011" font-family="'Segoe UI'" font-size="13.3" textLength="7.169531" fill="rgb(0,0,0)">5</text><text style="font-style: italic" x="50.09912" y="26.26201" font-family="'Segoe UI'" font-size="13.3" textLength="6.052539" fill="rgb(0,0,0)">x</text><path d="M 61 15 L 71 15 " fill="none" stroke="rgb(0,0,0)" stroke-width="1"></path><path d="M 66 9.8 L 66 19.8 " fill="none" stroke="rgb(0,0,0)" stroke-width="1"></path><text x="74.71016" y="18.28633" font-family="'Segoe UI'" font-size="14" textLength="7.546875" fill="rgb(0,0,0)">3</text><rect x="85.25703" y="14.8" width="1" height="1" fill="none" stroke="rgb(0,0,0)" stroke-width="1"></rect><text x="89.25703" y="18.28633" font-family="'Segoe UI'" font-size="14" textLength="17.25391" fill="rgb(0,0,255)">sin</text><path d="M 115 8 A 4 7 0 0 0 115 22" fill="none" stroke="rgb(0,100,0)" stroke-width="1"></path><text style="font-style: italic" x="116.173" y="18.28633" font-family="'Segoe UI'" font-size="14" textLength="6.371094" fill="rgb(0,0,0)">x</text><path d="M 124 22 A 4 7 0 0 0 124 8" fill="none" stroke="rgb(0,100,0)" stroke-width="1"></path></svg>

Your question is very ambiguous. Since SVG is an image format then
this implies that you want an image of the expression somehow but
there are many different ways that an expression could be represented
as an image. Do you want an image of the tree or a typeset equation
(like from LaTeX) or something else?

That's just the contents of an SVG file. If you had an SVG file then
you could just read the file to get the string.

An SVG file represents an image but you haven't said what you want an
image of. Also you don't say *why* you want an SVG image. The usual
reason for wanting SVG is to have an image in a webpage but the
easiest and potentially best way to have a typeset equation in a
webpage (assuming that is what you want) is to use Mathjax in which
case you should just convert your expression to LaTeX:

In [3]: latex(x**2)
Out[3]: 'x^{2}'

Yes i need typeset equation in a webpage. I know about mathjax, i understand that there is a possibility to convert sympy tree expression to latex and then handle it on client web page and convert to svg with mathjax.

But is there any way to do this on server (not in client web page) in order to send svg result to the client then.

You can run Mathjax on the server:

Yes, but this is not the same server where the sympy runs ...

SymPy doesn't directly support SVG output. Your best bet would be to
find some tool that supports converting LaTeX or MathML to SVG, as
SymPy can export to both of those, or something that converts PDF to
SVG (SymPy can generate a PDF with preview()).

This page suggests some options for converting LaTeX to SVG
https://askubuntu.com/questions/33196/how-to-convert-latex-equations-to-svg.

If one of these tools works well maybe we can add support for it to preview().
