Network topology

Dude I would like to draw out the network topology into other applications, there are no corresponding API. Thank you!

Dude can save the network layout image as a file, and you can use this image in other tools. Or you meant something else? Yes, there is no API

Thank you!
I know dude can save the network layout image as a file, But how can I call directly the network layout which has been drawn with dude to a third-party application, The third-party application directly use the network layout.
