The command-line utility ltxsvg is intended to be used as preprocessor
converting TeX formulae embedded within XML file to SVG format. The program
uses an approach similar to one that implemented in MetaPost btex … etex
construct. The ltxsvg uses TeX and dvisvgm to render the formulae.
The program looks for any occurrence of <math> or <display> elements bound
to the custom namespace "https://github.com/urbic/ltxsvg" in the given XML
document and replaces it with the SVG rendering. The text content of these
elements is interpreted as TeX formula.
The preprocessed XHTML and SVG documents can be browsed in any SVG-capable browser without use of tools such as MathJax.
-
Support for inline and display formulae.
-
Special handling of the formulae in XHTML documents which allows to align rendered formulae on the baseline and adjust its size to fit the size of the surrounding text.
-
Special handling of the formulae in SVG documents which allows to place the rendered formulae to the specified position. It is also possible to attach the rendering at the specified point as well as does the
labelcommand in MetaPost. -
Optimization intended to reduce the size of the resulting file and to accelerate its rendering in a browser window.
-
Caching the rendered formulae.
-
In-place conversion.
