Thanks, that did the trick. One thing I'm still having trouble with is
getting transports other than raw to work with
image_transport::SubscriberFilter. If I pass
image_transport::TransportHints th(transport) to
image_transport::SubscriberFilter, where transport is "compressed" or
"theora", I never seem to get any data. rxgraph -t shows that my node is
connected to my image publisher on the right topic, but the callback
never gets called.
Thanks,
-Dan
