[idvusers] API for vertical section plots

Dear IDV folk,

I've seen that IDV can produce vertical section plots.  I'm interested in 
re-using this capability in other software (ncWMS) if possible.  I'd like to 
produce a plot as a standalone image (i.e. outside the context of Swing or any 
particular desktop), ideally as a BufferedImage.  Could someone please point me 
to the relevant bit in the libraries please?

Thanks,
Jon
