Ziamath can be installed using pip:

pip install ziamath

Ziamath depends only on two pure-Python packages: Ziafont, for reading TTF/OTF font files, and latex2mathml for parsing Latex math expressions.

Drawing Equations

The ziamath.zmath.Math class processes and draws a given MathML <math> element. Set up a Math object by providing a MathML string:

import ziamath as zm

eqn = zm.Math('''

In Jupyter notebooks, the Math instance will be rendered in the cell’s output. The raw SVG is obtained using ziamath.zmath.Math.svg(), for SVG as a string:

eqn.svg()[:80]  # Only show first 80 characters...
'<svg width="23.907" height="22.153" xmlns="" viewBox="'

or ziamath.zmath.Math.svgxml() for the SVG in an XML ElementTree.

<Element 'svg' at 0x7efd641b09a0>

The Math class takes optional parameters for font file name and font size. The font file must be math-enabled, with an embedded ‘MATH’ table.

Drawing Latex

To render a math expression in Latex format, create the Math object using ziamath.zmath.Latex():

zm.Latex(r'c = \pm \sqrt{a^2 + b^2}')

The Latex class inherits from the Math class. Be sure to use raw strings (prefixed with an r) so that slashes for Latex commands are interpreted as slashes and not string escape characters.

Display Mode and Inline Mode

Latex math is drawn in display (block) mode by default. To render inline (text) mode, set the inline parameter to True.

zm.Latex(r'\sum_a^b', inline=False)  # Default display mode
zm.Latex(r'\sum_a^b', inline=True)  # Inline mode

Mixed Math and Text

:py:class:ziamath.zmath.Text renders mixed math and text into a single <svg> element, drawing both math and text characters as SVG paths. It takes a string input with math expressions enclosed between single dollar signs $..$ for inline-mode math, and double dollar signs $$..$$ for block or display style math. Different fonts may be used for the plain text and math portions.

    r'''The volume of a sphere is
$V = \frac{4}{3}\pi r^3$
or in terms of diameter,
$ V = \frac{\pi d^3}{6}$.
''', halign='center')

The textfont argument may be the path to a font file, or name of a font-family such as “sans”, “sans bold”, etc. The mathstyle provides styling to the math expressions.

Text objects support rotation (in degrees) and color (CSS named color or hex color value):

zm.Text('$\\sqrt{a}$', rotation=30, color='mediumslateblue')
