Currently are supported two values -- <literal>plain</literal> and <literal>latex</literal>. Empty value means that you are not using TeX math at all.</para> <para>Preferred way for including TeX alternative of math is inside of <tag>textobject</tag> element. Eg.:</para> <programlisting><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></programlisting> <para>If you are using <tag>graphic</tag> element, you can store TeX inside <tag>alt</tag> element:</para> <programlisting><inlineequation> <alt role="tex">a^2+b^2=c^2</alt> <graphic fileref="a2b2c2.gif"/> </inlineequation></programlisting> <para>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.</para> <para>If you want equations in HTML, just process generated file <filename>tex-math-equations.tex</filename> by TeX or LaTeX. Then run dvi2bitmap program on result DVI file. You will get images for equations in your document.</para> <warning> <para>This feature is useful for print/PDF output only if you use the obsolete and now unsupported PassiveTeX XSL-FO engine.</para> </warning> </refsection> <refsection><info><title>Related Parameters</title></info> <para><parameter>tex.math.delims</parameter>, <parameter>passivetex.extensions</parameter>, <parameter>tex.math.file</parameter></para> </refsection> <refsection><info><title>More information</title></info> <para>For how-to documentation on embedding TeX equations and generating output from them, see <link role="tcg" xlink:href="TexMath.html" >DBTeXMath</link>.</para> </refsection> </refentry>
