A while ago I mentioned that I was trying to display static JUNG graphs with a MASON portrayal class. The display is working very well at the moment (in no small part due to the help I received), but constantly redrawing the graph is putting a heavy load on my system. If I remember correctly, Sean suggested caching the graph as an image and redrawing that instead, since the underlying data never changes. This should give me a nice boost in performance.
I was hoping someone could give me a few pointers on how to actually do that. There's a tutorial about displaying an image in a portrayal in the MASON How-Tos (https://cs.gmu.edu/~eclab/projects/mason/docs/howto.html#display2d), but I can't figure out how to store my graph as an image in the first place. There must be a way to rewire the output of my portrayal class to draw directly into the image. Any help would be much appreciated.
