Title: Edge layout with cgraph for fixed node position
Tags: c;graphviz
Question: I'm using Graphviz and cgraph to layout some graphs and, for some cases, I already know the positions I want my nodes to be at (as they form a subgraph of a bigger graph).
Using the dot command line tool, you can add the -Knop layout option, but if try gvLayout(context, graph, "nop") in my code, or call gvParseArgs for dot -Knop arguments, the resulting graph has no edge routing, even though I have agset(graph, (char*)"splines", (char*)"true") in my code.
Is there any way I can achieve such edge routing for fixed node positions in cgraph?
Comment: No, any of the (standard?) layout algorithms works just fine.

Comment: And if you specify `dot` instead of `nop`, you don't get a segmentation fault?
