Hi Josh,

Sorry for the delay to reply, I'm just back from the ICMC... and  
welcome to the Guidolib!

This is not an architecture issue. Actually, the export features of  
the GuidoQuartzViewer need to be restored. The mac os graphic api has  
evolved a lot since the viewer initial design and the export features  
have not been properly maintained. On Mac OS 10.5, there is also now  
whole bunch warnings due to obsolete api... :-(
Note that the library now supports Qt and that we're currently trying  
to save time in maintaining cross platform developments. However, any  
fix to the GuidoQuartzViewer issues will be welcome.
Note also that a switch of the repository to svn is currently in  
progress (with significant code restructuration) but not yet available.

Very interesting. I'd like to see some examples.
