Exporting equations as SVG

Convert Matplotlib MathText to SVG before you paste it into a vector graphics editor:

import erlab.plotting as eplt

svg = eplt.copy_mathtext(r"$e^{i\pi} + 1 = 0$")

The function returns the SVG text and tries to copy it to the system clipboard. Paste the result into the target application. If clipboard access is not available, save the returned text:

from pathlib import Path

Path("equation.svg").write_text(svg, encoding="utf-8")

Set outline=True when the target system does not have the required fonts. Outlined text preserves its appearance, but it is no longer editable as text. See erlab.plotting.copy_mathtext() for font and MathText settings.
