In ppt slides equations are embedded OLE objects. Each OLE object consists of two parts: - snapshot in WMF format. This is what needs to be rendered. - the actual binary OLE data. This part is activated by double-click.
Since rendering of WMF is not supported by JDK, the equations don't appear in the created images. In next versions of HSLF I plan to use Batik http://xmlgraphics.apache.org/batik/ which includes a WMF transcoder: http://xmlgraphics.apache.org/batik/javadoc/org/apache/batik/transcoder/wmf/tosvg/WMFPainter.html If you feel like researching this subject, I can explain how to extend HSLF code to use third-party image renderers.
