## tex.math.in.alt

tex.math.in.alt
— TeX notation used for equations

## Synopsis

<xsl:param name="tex.math.in.alt"></xsl:param>

## Description

If you want type math directly in TeX notation in equations,
this parameter specifies notation used. Currently are supported two
values -- `plain`

and `latex`

. Empty
value means that you are not using TeX math at all.

Preferred way for including TeX alternative of math is inside of
`textobject`

element. Eg.:

<inlineequation>
<inlinemediaobject>
<imageobject>
<imagedata fileref="eq1.gif"/>
</imageobject>
<textobject><phrase>E=mc squared</phrase></textobject>
<textobject role="tex"><phrase>E=mc^2</phrase></textobject>
</inlinemediaobject>
</inlineequation>

If you are using `graphic`

element, you can
store TeX inside `alt`

element:

<inlineequation>
<alt role="tex">a^2+b^2=c^2</alt>
<graphic fileref="a2b2c2.gif"/>
</inlineequation>

If you want use this feature, you should process your FO with
PassiveTeX, which only supports TeX math notation. When calling
stylsheet, don't forget to specify also
passivetex.extensions=1.

If you want equations in HTML, just process generated file
`tex-math-equations.tex`

by TeX or LaTeX. Then run
dvi2bitmap program on result DVI file. You will get images for
equations in your document.

### Warning

This feature is useful for print/PDF output only if you
use the obsolete and now unsupported PassiveTeX XSL-FO
engine.
