描述
WPMathPub renders mathematical equations in WordPress using the mathpublisher rendering engine, supporting both pmath native syntax and LaTeX-style input and generating high-quality PNG images with transparent backgrounds.
Unlike MathJax-based plugins, WPMathPub performs server-side rendering, producing static equation images that display consistently across browsers and devices without requiring client-side JavaScript.
This approach provides reliable rendering for:
- WordPress posts, pages, and comments
- Cached pages
- Environments where JavaScript rendering is not desirable
- RSS feeds and feed aggregators RSS example
WPMathPub extends the classic mathpublisher engine with modern WordPress integration including shortcode support, LaTeX translation, image caching, and configurable rendering options.
Mathematical Equation Rendering
Mathematical expressions can be embedded directly into WordPress content using the pmath shortcode.
Example:
[pmath]x^2 + y^2 = z^2[/pmath]
Custom size and color:
[pmath size=18 color="blue"]E = mc^2[/pmath]
LaTeX input with inline text:
This is a fraction: [pmath latex=1]\frac{a}{b}[/pmath]
Expressions are rendered as PNG images using the GD and FreeType libraries and cached for efficient reuse.

常见问题
-
How do I get started with WPMathPub?
-
Here are three references:
- Check out the WPMathPub math publisher page for the user guide.
- Check out the WPMathPub syntax page for a complete cross-reference of all pmath native and LaTeX supported commands.
- Check out the WPMathPub support page for video tutorials and a donation link in support of this project.
-
Does this plugin require MathJax?
-
No. WPMathPub renders equations server-side as PNG images using the mathpublisher rendering engine.
-
Does it support LaTeX?
-
Yes. WPMathPub includes a server-side LaTeX translator that converts standard LaTeX math commands into native pmath syntax before rendering. The result is identical PNG output — so a LaTeX expression and its pmath equivalent share the same cached image file, with no duplication. See the full command reference on the WPMathPub syntax page.
-
Where are rendered images stored?
-
Rendered equation images are cached in:
/wp-content/uploads/wpmathpub/math-img/ -
Why does the plugin generate PNG images instead of SVG?
-
The plugin preserves compatibility with the mathpublisher rendering engine, which produces raster images. PNG output ensures consistent rendering across browsers.
