Subject: [Rd] help with R rendering engine
Message-ID: <47AB8AF9.5000202@gmail.com>

I'm doing some work on a potential patch to the Bioconductor package 
Rgraphviz and have some questions on code that is contained in engine.c. 
In particular, I am developing some custom shapes using polygon and need 
to make sure that, with rendering, the line connecting the centers of 
two polygons stops at the border of each polygon. The polygons can be 
transparent, so the option of just rendering the lines first won't work.

Is there some help for me with an R internal or perhaps a higher level 
function?

Thanks,
Mark
