|With the explosion of graph-based data, the Graphviz project offers new contributors excellent opportunities to explore new concepts, or enhance tools that thousands of projects already use. We're looking for programmers and technical experts in core algorithms, interactive and command line programs, and rendering. This page provides a list of possible open work. And, of course, we are open to your suggestions. If you are interested, please contact us.|
I published on github a new library (https://github.com/CapelliC/loqt),
rendering xdot to Qt. There is also an example GUI.
It's of course a WIP towards some fresh view on (SWI)Prolog.
You will need a (very!) recent version of libxdot...
The easier way: open lqXDot_test.pro with QtCreator (I used Qt 4.8)
I've been pleasantly surprised by the quality of xdot rendering, using Graphviz as a library.
Actually, a simple translation from xdot output to Qt graphics primitives now yields a performant and accurate display of complex graphs.
I think I will try to bypass xdot/libxdot to get further memory/time gain, using gvrender_engine_t...
Now my question: it's possible to get gvmap working at the same level of, say, xdot, thus avoiding FILE IO ?
I understand from license terms I could compile the relevant parts, or I'm wrong here ?
I use graphviz (v2.28.0) as a library in a C++ application and I would like to render graphs using the dot layout. Everything works fine until I call the gvLayout(_context, _graph, "dot"); function which outputs the following error :
