-    <title>LaTeX Filter</title>
-</articleinfo>
-<simpara>The AsciiDoc distribution includes a LaTeX filter that translates LaTeX source
-to an image which is automatically inserted into the AsciiDoc output document.
-Although it can accept any LaTeX source, the primary use is to render
-mathematical formulae (see the examples below).  The filter implements the
-<emphasis>latex</emphasis> Listing block and Paragraph styles.</simpara>
-<simpara>Two image formats are supported; PNG and SVG. PNG is the default since that
-was the first format that this filter supported. However, SVG is a better
-format since it&#8217;s scalable. Using SVG make formulas look good in both PDFs
-and on web pages. SVG will also scale well when zooming in on a web page for
-example. It is recommended to always use the SVG format. This can be done by
-setting the <emphasis>imgfmt</emphasis> parameter to <emphasis>svg</emphasis>, as is done below. An even better way
-is to set the global attribute <emphasis>latex-imgfmt</emphasis> to <emphasis>svg</emphasis>. Then SVG will be used
-for all formulas.</simpara>
