Automatically Create Bline from Silhouette

I’m wondering if there’s a way to automatically create a bline from a silhouette.

Like this for example, would I need to manually trace it or is there a way to automatically get a bline around it?

You can’t do that in Synfig Studio at present. However, even when I used to use Flash which could trace shapes automatically, I never used it. When I’m producing rigs for animation I like to control how many vertices there are (as few as possible!) and where they are as I found that tracing a shape automatically never, ever saved me any time.

If you really need to trace the shape, I would trace it in Inkscape using the automatic tracer there and then use nikitakit’s .SIF exporter to get the resulting shape into Synfig Studio. ( viewtopic.php?f=1&t=2953 )

Thanks! Very helpful. I see your point and will have to figure out if this will really save me time.
