OK...sorry for the unnecessary email traffic, I figured it out. Here is
the explanation for anyone that comes along looking in the future.
Turns out I was trying to reference the variables wrong. I was doing:
bestNet = image->netlist[0]
Which wasn't working properly.
When I use:
bestNet = image->netlist->next;
All is good. I also found the looping code to be:
for (net = image->netlist->next ; net != NULL; net =
gerbv_image_return_next_renderable_object(net)) {
Thanks,
Curtis
