我正在寻找一种从模板中嵌入的 LATEX 源代码生成方程 PNG 图像的方法。例如，给定：
[% FILTER latex_display ]
\begin{eqnarray*}
\max && U(x,y) \\
\mathrm{s.t.} && p_x x + p_y y \leq I \\
&& x \geq 0, y \geq 0
\end{eqnarray*}
[% END %]
我想得到输出：
<div class="latex display"><img src="equation.png" width="x" height="y"></div>
最终应显示为：
我正在使用 ttree 离线生成文档。我知道 Template::Plugin::Latex 但这是为了生产来自 LATEX 模板的实际文档。
有什么建议吗？
更新：
我很欣赏这些建议（并且我已投票赞成）。然而，它们并不完全是我所需要的。我真的很感激一些关于模板工具包插件或过滤器入门的建议。
I am looking for a way of generating PNG images of equations from LATEX source code embedded in templates. For example, given:
[% FILTER latex_display ]
\begin{eqnarray*}
\max && U(x,y) \\
\mathrm{s.t.} && p_x x + p_y y \leq I \\
&& x \geq 0, y \geq 0
\end{eqnarray*}
[% END %]
I would like to get the output:
<div class="latex display"><img src="equation.png" width="x" height="y"></div>
which should ultimately display as:
I am using ttree to generate documents offline. I know about Template::Plugin::Latex but that is geared towards producing actual documents out of LATEX templates.
Any suggestions?
Update:
I appreciate the suggestions (and I have voted them up). However, they are no quite what I need. I would really appreciate a few pointers towards getting started with a Plugin or Filter for Template Toolkit.

维基百科做了与你想要的类似的事情。他们使用一个名为
texcv的程序。然后你还有 MathJAX 它更针对网页中的动态数学渲染。texcv是根据用 OCaml 编写的链接页面，但是由于 Mediawiki 的其余部分是用 PHP 编写的，我认为您在重新利用该程序以与 Perl 一起使用时应该不会有任何问题。Wikipedia does something similar to what you want. They use a program called
texcv. Then you also have MathJAX which is more aimed at dynamic math rendering in web-pages.texcvis according to the linked page written in OCaml however since the rest of Mediawiki is written in PHP I don't think you should have any problem with repurposing the program to use with Perl.你应该看看jsMath，MathML，或 mathjax
you should take a look at jsMath, MathML, or mathjax
上的这些文档
Template Toolkit网站应提供设置插件或过滤器所需的所有信息：一旦您将 LATEX 转换为 PNG 排序，那么您可能需要使用 重定向。 POD 示例：
希望有帮助。

These docs on
Template Toolkitsite should provide all necessary info to setup a plugin or filter:Once you have your LATEX to PNG conversion sorted then you probably need to save it as a file using redirect. Example from POD:
Hope that helps.
