最小示例
from pathlib import Path
from py_katex import render
result = render(r"x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}",
font_size=28, display_mode=True, backend="cpu", format="svg")
Path("formula.svg").write_bytes(result.data)
py-katex "x^2+y^2=z^2" --display --backend cpu -o formula.png
能力与边界
支持符号、字体、分式、根式、脚标、极限、伸缩括号与重音、矩阵、AMS/CD 环境、编号、作用域宏与显式离线资源。 默认错误会抛出异常；选择可见错误输出时应检查诊断，不能将错误图当作成功公式。 HTML/MathML 序列化、任意浏览器 CSS、交互和独立 contrib 插件（如 mhchem）不属于核心静态范围；不承诺与浏览器逐像素相同。
