Is there any API to convert a gv.Graph object to numpy.ndarray?

[BoyuanYan]

I need to generate network topo image and handle it immediately. So, saving a gv.Graph object to png image file and reading it by PIL.Image is wasting time. And could anyone tell me any method to convert a gv.Graph object to numpy.ndarray object in memory but not on hard-disk?

If I correctly interpret your use case, I think you might try the .pipe()-method of your Graph object (see docs), probably feeding the return value to the PIL.Image.frombytes constructor (docs).

I think a method (new feature) for directly converting a graphviz.Graph object into a numpy.ndarray (two-dimensional bitmap of raster points, I assume) would be out of scope for the graphviz package.
