SVG is much more widely supported than MathML by renderers such as vector graphics packages, Web browsers and document formatting engines.
pMML2SVG provides a means of transforming MathML presentation markup into SVG. A distinguishing feature is that this transformation is implemented in XSLT (2.0), which allows it to be elegantly integrated into XML-based workflows.
Its raw installation requires the presence of STIXBeta fonts. However, pMML2SVG comes with facilities to create suitable font-metrics files from other TTF Unicode fonts.
The distribution includes XSLT stylesheets for transparent transformation of MathML embedded within XHTML and XSL-FO.
The picture on this page is a screenshot of SVG renderings created by pMML2SVG.
See some more screenshots.
There is a side-by-side comparison of MathML and its SVG renderings created by pMML2SVG (requires a MathML- and SVG-enabled browser and STIXBeta fonts; Firefox 3.5 is recommended, earlier versions render this page very slowly and have memory leaks).
The user documentation includes a small subset of the aforementioned examples.
All mathematical examples are pMML2SVG renderings produced by processing XHTML and XSL-FO DocBook output using scripts provided with pMML2SVG.
