I do that with the editor, or by writing a bash script, or a python script, to read the file and create a new one with whatever changes I want to make.

I think I might have a python library from an old project that implements the file syntax specification from the manual

In any case, it would be a good idea.

I would get the image into inkscape, at which point you could either

1) if it is a non convex shape/logo, import into inkscape, do some edge detection, and apply a suitably fat stroke width to the path, export as graphic with a grown margin, then import the graphic, apply edge detection to the enlarged graphic, and export the paths with

inkscape2pcb

2) if it is a convex logo/shape, import graphic into inkscape, scale enough to create a grown border, do edge detection, and export path with

inkscape2pcb

See

https://inkscape.org/~erichVK5/%E2%98%85inkscape2pcb

Inkscape2pcb allows some scaling too.

The pcb-rnd version of inkscape2pcb will also export polygons as well as lines degining it's border in the footprint, after confirming that the path defines a simply polygon.

Hey folks. I'm designing a board that needs to have a very complex
outline. Starting from an image file, I've gotten what I need into the
silkscreen layer, but now I'd like to essentially take the shape that's
there and draw a line 1mm or so around the outside of the entire shape,
for the outline.

Can anyone suggest an automated way to do this? I'd just trace it,
but the outline is, as I said, very complex.

Thanks,
-Dave
