[Inkscape-user] Batch trace of bitmaps

Hi Inkscape list,

Is it possible for inkscape, or some other command line utility, to do batch tracing of bitmap to svg files? I've seen that through Inkscape verbs you can use "SelectionTrace", but that still requires manual input.

I've tried potrace, but that only works on black and white images, and I've tried autotrace but that only produces jigsaw-like svgs and I want ones where the different colours are stacked on top of each other

Thanks for any help that you can give

Antonio
