GEF5 Export Diagram as SVG [message #1775119]

I want to allow my users to export the diagram they've created as an SVG (and PNG). I've found some information on how to do that in GEF 3.x and have implemented the PNG export back when we used 3.x. Now that we have moved up to GEF 5, I can't find any documentation on how to export the diagram. Any advice?

Hi Ken,

you can export to png using JavaFX snapshotting functionality, however, you might need to tile the rendering by yourself since JavaFX will throw an exception when trying to snapshot a large node.

Apart from that, there is some unmaintained code out there for converting a JavaFX scene graph into an SVG vector image. This is done by traversing the JavaFX scene graph and creating corresponding SVG elements for the individual javaFX nodes. Note that this approach of course has some limitations w.r.t. the JavaFX nodes that can easily be "transformed" into SVG.
